I've had my pair of this model for just a few days and have gotten accustomed to it and thank the designers for the features it was built with. I do plan to look around more for cons so I do not get blind sided by any of them since "cons" are few and far between the "pros" reported by useres. Thanks for your review!!
Thanks for taking the time to watch. Definitely spend time getting to know how to use it so when the time comes you can put your effort into other things and not learning the generator. Also, I've found if they're going to fail they typically do it early on so use the heck out of it for the first month or two and get to know it and battle test it. I will have more content coming soon if you want to subscribe.
I bought the D2 + battery effectively doubling the power. I see there's the larger backup battery (~ 2K?). I don't plan on going off grid, but my hope is to run a lcd TV, modem, light and heating blanket if the power cuts in winter. Something tells me these are more than enough to do this.
I tried to come up with a condescending remark, but I couldn't come up with one. This is an excellent review on a very good product. Your suggested improvements for the Delta 2 are spot on.
Sorry for the delay in my reply, youtube had your comment held for review for some reason and I'd missed it. I agree, this should last a long time on your CPAP! You should report back after you have some time with it, and let us know how long it lasts. I'm betting 3 nights worth, or more. If you have the DC plug for your CPAP you should try it and the AC plug and see which you get more use from, that would be interesting. Thanks for watching!
Yes! Just keep in mind the 2kWh expandable battery from the Delta Max is NCM chemistry with a shorter lifespan than the spare battery (and main battery) on the Delta 2. My guess is by this time next year they've replaced most of their line with LFP battery chemistry so if you don't already have a Delta Max battery it may be wise to hang on for a bit!
33:47. Oh it's a **LOT** more than a doubling in cycle count. Jeff Dahn (one of the world's foremost experts in battery chemistry) has shown that if you keep LFP within its sweet spot there is no measurable degradation. The sweet spot being between 80% and 50%. Of course, that's a pretty small window, but if you were to say keep it between 85% and 30% your cycle count is probably 10x that of fully cycling the cells. Basically the closer you stay to the sweet spot, the less wear you put on the cells. Also, the less amount of time you spend outside of the sweet spot the better. (Bad, bad, bad, to completely discharge a battery, and then to store it like that for instance.) These usage guidelines hold true for regular NCM and NCA chemistries as well, just more damage is done as you cycle the cell, and you probably aren't going to avoid wear altogether (though you can seriously cut it down).
Yep. I typically do a couple full charges and discharges to program the BMS and test to make sure full capacity is there, then after testing and reviews I set them to run from 30%-90%. Prowse says there is no need as you'll likely calendar age them first and he's probably right, but I'm conservative and still do that when I can.
I agree! That charges as fast as my iPhone and it has a large 1kWh battery bank. Makes it so much more usable and the reason I grab it over my powerstations that take 5+ hours to recharge.
You probably also remember that all quick charging and quick discharging shortens the life of the battery. So it's not worth charging with 1200W power and discharging with 1800W power just because you can do that.
Glad it helped you to differentiate! I still think the OG Delta is a good unit, but unless it's significantly less I think your money is better spent on the 2.
I finally purchased one today... power went out last night for 90 minutes, my UPS kept my TV on ECO mode and cable box on consuming 40w, still had about 40 minutes left on UPS when power came back....
Xboost is something you by all means try to avoid using, but if you absolutely have no alternative it comes in handly. It lower the voltage so the receiving device will be satisfied regarding amps, like you explained at 35:20 and 38:20. Not all devices will function with a lower voltage though, so use only when absolutely needed. So yes, Ecoflow should as a default have it turned off! So xboost is not really outputting 2200 watt (Amps times voltage) but when it is on it can deal with devices that normally would require 2200 watt (or 10 or 20 amps depending on where you live). It is also not like peak performance as that will last much shorter then xboost. Xboost is for running a high amp thirsty device for longer periods. Basicly if you have a device that wants a lot's of amps and it not very pickly on the voltage, you might get away with it. Think resistive heating, large electric motors etc. Typicly you use it for one device at a time. Do not use it to run multiple devices that total more then 1800 watt. And do not use it when powered into AC at the input side :-) I believe Ecoflow blocked that anyway.
Yep you got it. It's a good advanced user tool and as such I'm glad it's there, but it seems like something that would create more problems for users and their support than it helps.
@@reviews2you I say it is only for people that know what they are doing or have enough money to risk breaking it. Meanwhile I am a bit in doubt about the fan-noise. When running on or charging the battery I am fine with the fan-noise, when running on AC(in) it shows this does not have a transfer switch but does AC->DC->AC. Which not only is noisy but also inefficient. That is why I installed a real transfer switch at home which uses the Delta 2 as generator in case the grid goes down.
@@HansKeesom It sounds like you have a pretty great setup. I noticed since my review the fans have gotten less noisy from firmware upgrades. They clearly reduced the RPM under certain conditions.
@@reviews2you Absolutely, for AA it is fine to have NMC but once you get to hundreds of wH I like to reduce firerisk. My official Shimano e-bike batteries of 410 and 500 wH are kept in a fireproof bag, just in case they go off
Yes, sir! Just keep in mind it is different chemistry and will degrade a bit faster, but if you already have it then heck yes, that's perfect for you and it should increase the efficiency of the inverter by having a larger battery bank.
Great review.. this delta 2 is like a darn roller coaster.. it has a lfp battery 👍🏻, can’t dual charge👎🏻, Is expandable👍🏻, only 1kwh in lfp or 2 in nmc 👎🏻, price is pretty good👍🏻.. you get the point. At some point, someone will come up with a hack on that extension I’m guessing, that can run like a 48v battery. You can do it with the solar input, but 500 watts and it won’t charge kinda sucks. Only other thing I wish would be that it work with the ecoflow smart generator, that is a pretty neat system that has some benefits.
Thanks and I agree with your take away. The dual charge thing is a bit of a bummer. I'm not sure how many people would actually do that, but it would be nice to have. I'm willing to bet they revamp the Delta Max w/ LFP and it will have more expandability. Overall they still keep getting better each year. I just got a new River 2 Max and it's much better than the last generation (including app features). Still a long ways to go, but compared to what we had to choose from 3 years ago this industry has come a long ways, and Ecoflow is one of the top companies driving this evolution (Bluetti too). Thanks for taking time to watch my video.
@@reviews2you yeah, I was looking at the river 2 pro (but it was out of stock) it has great features for the price. I liked the max too, but wasn't quite big enough. Just picked up the delta 2 and 220w panel on amazon for cyber monday deal for 1099, which is an amazing deal.. I decided to wait on the extended battery to see if they make a extended 2+kwh battery thats lfp..
@@jmac1099 The new River 2 Pro isn't out yet, they have had some issues with production or the unit, unclear which. It doesn't have the expandable battery that the current River Pro has, which I have. I think a good combo is either the Bluetti EB3A or the Ecoflow River 2 Max for small then the Delta 2 for a good mid sized unit then Bluetti AC500 for a large unit. I have all of them, I'll get more reviews and comparison up at some point.
The dual charge I solved with an external battery(100 Ah LFP with heatmats as it is located outside my house) where my solar is dumped. When I see the external is getting full I turn off the AC-in of the EcoFlow battery's I have and they get charged from the solar. That likely means some losses but will also give solar a battery to go when the EcoFlows are full. The external battery is charged with Victron MPPT's that have a load port that can be programmed to shut off when voltage is low, thereby protecting the external battery from getting discharged to much. Ecoflows are set to charge to 95% SOC which is respected both when AC charging as when DC charging........ In that case the electricity can stay in the external battery 2 in nmc is no negative for me because nmc is a no-go for me :-)
Was very happy with my new Ecoflow 2000, although concerned about the battery cycle life, Unhappy with the deal, paid the top then price in South Africa, the new Ecoflow 2 came out the following week without warning and 20% cheaper for 5 times battery cycles, a big factor when power is down 25% of the time.

Sorry for the delay in my reply, youtube had your comment held for review for some reason and I'd missed it. Yeah as long as you don't exceed the output limitations you should be good. You can even use a power strip with it even though they may advise against it, I've been successful with that. Or a USB C to USB hub ;)
Excellent review and what are you doing with all those powerstations?! Well, I'm just like you; I have a few myself and getting more, including this Ecoflow Delta 2 unit. Have you looked at the Pecron 2000LFP?
Thanks, Jason! I just like to tinker with them, I often sell them and replace with newer units as the market is flooded with new battery generators these days. I'm in the process of building an off grid backup system with server rack batteries now. Sold my Battleborn batteries and going with some rack batteries, I may do a video after I have it up and running. I have checked out the Pecron but haven't tested it yet. I may get my hands on one here in the next couple months, on paper and from what I've seen it seems like a solid choice.
So the ac inverter is like 12-13% more efficient than straight thru dc? That seems to be just the opposite of what I had always heard was the usual case. Is that also true for the Delta 1300? I have a Delta1300 now and have used it to power my 12v fridge (Alpicool T50) on camping trips, but always in dc mode thinking that was more efficient. The fridge can also run on ac and I guess if I buy the Delta 2, that should be my new default. Any comments Jason?
Yes that's right. It's a common misconception that there is no (or less) loss with DC which is understandable since the battery generator has its' energy stored in DC. However, keep in mind that battery pack is 51.2v so to get it to 12v you have to step it down with a regulator and there is loss in that. It is actually common that DC output is less efficient than AC. Now if you have a no regulator and an internal pack with a lower voltage range you would get more from the battery pack but then as the battery SOC reduced the voltage would reduce and items like your fridge would shut off. I had the same question as you regarding the fridge. The short answer is I don't know for certain, and each fridge will vary with that. The reason is because your motor in the fridge is DC therefore it will have to convert the incoming AC to DC to power it and you'll have loss there, which may more than make up for the gain you'd get from the Delta 2 AC efficiency out. What you would have to do is charge the unit to 100% and run the fridge for a set amount of time and note the percentage battery drop on DC. Then charge it again to 100% and run it for the same amount of time on AC and note the battery drop. Your Delta 1300 has an AC efficiency of 83% and DC efficiency of 65% so in either case you're better off with the Delta 2. If you do the test I'd mentioned above, come back and leave the results, I'd be interested to see. My guess is that it's very similar either way.
Sorry for the delay in my reply, youtube had your comment held for review for some reason and I'd missed it! Thanks a million for using the link and glad it saved you a bit of money. Let me know what you think of it!
I believe they removed the fast/slow switch from the back because the delta 2 has Bluetooth where as the delta only had WiFi it’s a pain to connect just to change one setting when you are not at home you have your connect to the deltas internal WiFi hot spot which once you connect it shuts off your phones mobile data making your phone useless until you disconnect
The Delta didn't have any connectivity but the Delta 2 has WiFi and Bluetooth and you can adjust the input setting via the app. Would be cool to have a manual switch still on the back for when you didn't have app access (phone dead, not handy while camping etc). In any case, all this time later this is still a great device. Thx for stopping by.
@@reviews2you Yea I will alway prefer a switch over the app I hope they add an inverter on/off switch on the front of the next delta I have the max pushed into a cubby hole in my van so I can’t reach it I have to connect to the deltas wifi network every time I want to switch the mains on
I noticed at the end of your video the time left on the main unit was glitching. Going from 98hrs to 79 then 83 then back to 98. I bought the complete kit. The main unit and back up battery with solar panels and water resistant case. Found out it wasn’t enough power for my needs. And wanted to send it back in trade for their largest unit. They’re going to charge me a restocking fee as well as shipping fee. Total for all fees is 231 dollars. Not happy about that.
Interesting, I hadn't noticed that about the battery remaining time moving around until you'd mentioned it. This was an early production unit and they have released a firmware update, I'll have to pay attention on if it still does this. They did make some improvements since I did the review. You can now do silent charging, whereas I hit them a little bit for the noisy charging. I'm not sure what your needs are, but you can check out the Bluetti AC300 and AC500 if you need something much bigger. I prefer those over the Delta Pro because the PV input is greater.
Thanks for the reply back. I’m a newbie with this stuff. So wasn’t really sure myself. But 1800w isn’t enough. Seen the price of it and what it came with and figured that was a good deal. And took the chance and bought it. Then found out not enough watts. The others are really expensive for me. I decided to just keep the unit and put it threw it’s paces. I live off grid and was trying to give my diesel generator a break from time to time as well give my wallet a break lol. Maybe something other than solar generators would be better for me. 🤷🏻♂️
Hey Jason thanks for your content my question is what’s the best way to wire this unit to a 12v fuse block panel? After looking over the unit the 12 volt cigarette plug is not the most reliable connection for the 12v fridge I have in my van. Thanks 😊
Hey There - you could take a 12v out cig lighter cable and cut the ends and run them into your fuse block or take it from 110v AC side w/ a step down converter but that would be less efficient. I use temperature monitors in my freezers that notify me if the temp climbs which would be a good way to tell if something had come unplugged or shut off.
Good review I have the river pro and about to buy the delta2 one thing no one is mentioning is if you get the smart generator it would only be able to charge the main unit as it plugs into the plug the additional battery plugs into .. I'm guessing eco flow will release the Delta Max 2 in the new year with lifepo4 battery and increased solar input
Thank you. Yes it's too bad the spare battery doesn't have a second port so you could daisy chain the smart generator and the spare battery also needs DC output IMO. As a bonus having it's own XT60 input for car/solar charging would be nice. Bluetti does this on their higher end units. However, compared to the River Pro (I have it w/ the spare battery too) the Delta 2 is much better. They also updated the app since my review adding functionality including silent charging. $899 is the cheapest I've seen it and if you email Ecoflow you may be able to talk them in to sending you a free cover. I was able to get one and it's actually pretty nice. Enjoy! amzn.to/3BpPE54
@@reviews2you Yes, a xt60 on the external battery would be nice so you can charge it while away with the main unit or even charge an array of external battery's and use any of them when needed..... and transfer power to the main unit.... Wondering if we can connect a MPPT controller to the connector of the cable. I believe 48 volt is on it and if that is directly connected to the battery....... I have the river pro from kickstart with the EF-1500 battery. That battery is super. I use it in car to keep my cooler running for days while charging it while driving for sigarette lighter and from solar when not. It is a beast. And during these trips the River Pro can easily stay at home doing it's normal function keeping my internet up and running. I can use the 24 port of the EF-1500 to charge the main unit. Do use have a 24/24 DC for that..... as the voltage on the poles the higher then the input of the R600 can take ;-)
@@HansKeesom It's a good question. You may be able to hack it to get a charge controller to feed the spare battery. I have enough other battery generators that I wouldn't risk it as I could just grab a larger unit if I really cared but I like the question and ingenuity.
about the cable maybe the creators wanted for us to have a clear space for safety and cooling.. not only it needs space for air circulation but if you have a visible cable to have some time and store it correctly you will be aware and no destroy or kick it in accident!!!! as long as the fans are at same sides and opposite. then for sure its strategic trick that extra battery cables to go that way!!!!... prove me wrong. !!! so. what if that cable was in better possition and many of us wouldnt even care to take it out of small spaces so it operates in better place and have better cooling!!! only possible update in any future delta 3 for extra battery possitioning is to have the fans AND the cables front and rear .. but even then the rear has to be far from walls ...
Great video thank you. What would you recommend to keep charge at when storing for an extended period of time? I’ve been reading contradicting recommendations
Thank you. I believe if you read the manual it may say, and I think they say around 60%? However, I store all of mine at 80%. My thinking is that it's not left full so it isn't hard on the cells and has enough charge that if something happens where I need it then it still will have a good bit of power left. For best practices I recommend every 4 months to cycle them a little. I'll transfer energy from one to the next, charging them down some and then back up to 80%. Keeps the cells healthy this way. I also spend that time to update firmware and ensure everything is still working properly.
Yeah it has to charge more slowly as it reaches peak voltage, that's normal. Still far more watt hours appear to go in at that last little than proportionally should. I suspect it's to make it look like you hit 80% faster but I could be wrong. In either case it charges great and has been a great unit.
I have a buddy that uses two of them w/ a smart home panel but haven't tested one directly. New Delta 2 Max review coming up. Current Delta Pro is much larger and heavier. It's a good unit but the solar input is limited IMO. I predict they should have a new Delta 2 Pro out in the next few months so I'll hopefully get my hands on one of those. Subscribe to be notified.
No but you can set it to shut off at a certain low state of charge. That is a good recommendation to make to them, though. They did just add some automation in the update that rolled out this week allowing you to set charge/discharge times as well as prioritizing solar charging and the biggest one is to automatically turn on the AC inverter when the machine wakes up. So if it does but is plugged in to solar as soon as the sun comes out and it starts to charge the system and AC inverter will turn on which is huge.
@@reviews2you it doesn’t need to manage a battery, the second unit can manage itself; moreover one would gain the advantage of twice the receptacles, the ability to use it in separate rooms, have the same amount of power and best of all can be charged individually.
@@reviews2you Honestly, if you had to run 2kWh “continuously” would this really be a reasonable option? Besides the cooling fans cranking overtime, once it’s depleted (which won’t take long) you’ll then need a couple of hours for it to cool down before it will except any charge. Try it.
@@danielvazquez7482 I didn't say 2kWh continuously, you did. I understand fully what you're saying but you're not getting me. This makes one big battery that will be managed by one BMS, your proposal wouldn't work in the same way but if that's best for your needs then that's exactly what you should do. Thanks for watching
These Fancy Box's are sure not affordable to most people unless a Loan is taken out. I'll keep using My Deep Cycle Batteries and a good inverter. (My 12vdc Stuff runs great off the deep Cycle Batteries)
It would be hard to duplicate all this can do for the price in my opinion. You can only discharge a deep cycle to 50%, these you can discharge to 100% so you'd need two deep cycle batteries to equal the capacity one of these batteries can do, so right there you're sitting at $400, then a fairly junky 1,800w inverter will run you $120, then you have a high power battery charger capable of 1,500w charger. so on your 12v system that would be a 125 amp charger, that would run you several hundred but let's say you forwent the ability to charge fast and just got a $70 20a charger. Then you need a solar charge controller capable of 500w which is $130. Then you need a DC regulator at $40 then you need your usb/5521/cig lighter ports, at least another $50 if you can even find all of that. You're already over $800 and you have a massively heavy system that can't easily be moved and is inferior to the specs that's all in one here. Plus you don't have mobile app access or simple expandability.
@@reviews2you I already have all that stuff. No need to buy any more. My 3,000 watt Pure Sinewave inverter was Free. HEHE Most of My equipment is 12Vdc anyway.. 2 8D deep Cycle batteries in the back of My truck can run stuff for week or more. The only new stuff I've added to My equipment is 400 watts of Solar charging. When I camp, Power is the last thing I think about. It is a luxury more than a necessity. I'll take My phone and leave it turned off or just plug it into the Truck which has 2 batteries of it's own.
Great review from the UK, looking at buying this unit with the additional battery but I have a test/query for you, in the UK we have off peak electric so would the unit charge on solar during the day and set a mains timeclock on for sundown to buffer charge though the night? I am running a fridge in my summerhouse. Will the unit switch automatically through the cycle I mention? Thanks
Thank you. If I understand your question correctly you're asking if you can leave it plugged in to solar and and the wall at the same time and get it to just charge from solar during the day and the grid at night, is this right? If so, the short answer is no but I think there could be a work around. If you have it plugged in to the wall it will pull electricity but you could get a timer and plug the Delta 2 into the timer box then the timer into the wall and set it to kick on only during the hours you want it to charge from the wall. I think that should solve your problem. Good luck
@@reviews2you Yes thats correct I will use a wall timer to click on grid at night so the fridge/freezer works throughout the night. It was more a query as to the automation of the EcoFlow as once set up would it just cycle day and night like indicated without turning anything on say once the grid clicks on at night? Thanks for the reply.
Yes and no. You could use one unit to charge another via AC output on one but you wouldn't have a master/slave situation like you do w/ a spare battery where it can charge/discharge from one cable between the two units. The benefit of two main units is if one unit breaks you have one to use still, whereas if the main unit breaks and you have a spare battery only, you're out of luck. Also, w/ two main units you'd have double the solar input, but it just depends on how you'd use it whether it makes sense or not. If you plan to leave it unattended and want it to charge from solar and discharge to a load automatically that will be much more challenging to do with two main units. If you will always be nearby to manage them then buying two main units may make more sense.
They have $100 off the River 2 right now and if you spend over $3k you get a free River. $899 for the River 2 is 87 cents a watt hour, that's cheap for what you're getting. amzn.to/3AIfz7I
No this is 120v only, there is no way to run a 240v appliance with this. All the extra battery will do is extend your capacity but it won't change the inverter output voltage. If you need 240V from Ecoflow you can get two of their Delta Pros and you can link those together for split phase 240V. You can also do this with the Bluetti AC300 (and I think AC200 but you need to confirm that). Also, the Bluetti AC500 is on indigogo now for crowdsourcing at a pretty good discount. Two of those will run a split phase 240V load up to 10,000 watts. You can find the limited time special on the AC500 here: ac500-b300s-super-capacity.kckb.st/c8ba398a
This isn't designed to power your house, it's designed to power anything you could plug into your wall as well as DC items. I will be doing a review on this one coming up, but if you want something that can work as a home backup you could get something like this and plug in to a transfer switch. Just note it's for 120v only, not 240v. Also you may need more batteries, it can run up to 6. It's not my favorite home backup option but if you want something plug and play it's half off right now which makes it a pretty good deal: amzn.to/46EeZ9G
This one has 240v and 120v, but note you can only run one at a time but if you're feeding a transfer switch it can work. There are much more capable units but price starts going way up, not sure what you're aiming for. amzn.to/4cmN2on
It's a good question and the simple answer is no, they don't have charge timer options in app but you could get a smart plug like these and set them to turn on and off at certain times. amzn.to/3MjoG3a
Just in general how long would this run a fridge that is 6 amps, 115 volts and 6 Hertzs? If I added the extra battery? I know you can not say exactly so just an educated guess. Thank you awesome very through review!
Hey John, if you're pulling a full 6 amps the whole time (not just the peak start up number) then you'd only get about an hour and 15 minutes off the main unit, double with the spare battery. But usually refridgerators pull a lot to start then drop way down, averaging more like 100w/hr. In that case you'd get more like 8 hours off the main unit, and double that with the spare battery.
@@johnmal5975 Yeah if you have the spare battery with the main unit and enough solar you should have more than enough energy to perpetually run a refrigerator. Just make sure you stay within 60V max for the string of solar panels. It can accept up to 500W so with the main unit and spare battery if you can make even around 400w that's 5-6 hours to fully charge both batteries.
Thanks for watching. I got it early to do some testing and feedback prior to launch for Ecoflow. I decided before I threw it in a closet I'd do a detailed review for people so they could determine if it was right for them or not. It will be out day after tomorrow (16th) and those discount codes I posted will be active for the first 300 people (in the US) if you're interested.
@@Gkres0a Haha I hear you. It's going to be my new bug out power generator due to its light weight and high Wh capacity and inverter size (and solar input). So I'll keep it charged and ready to go. It's not perfect, but it's very hard to beat for its pricepoint as of today.
@@Jakepp235 Many will disagree and prefer the lighter weight of the NCM batteries, it's personal preference but for me (and I'd guess the majority of folks) I'll trade 2-3 lbs for safety and longevity. The counter argument is that you won't ever cycle it that much anyway, that something new will come out long before it hits its life cycle even with a NCM battery for most people, and I think that's largely a valid claim. However, I still prefer having safer battery chemistry and the fact it lasts much longer is just icing on the cake. The slight increase in weight doesn't affect me and they were able to keep this Delta 2 the same form factor size as the original so it didn't get larger because of it.
Hi Jason, you cannot turn off the D2 while it is charging from the AC wall-outlet, instead you first have to disconnect that charging cable. I don't understand the benefit behind this awkward setup. Did you find a reasoning for it?
@@reviews2you Thanks Jason! From that point of view it makes sense. However, I think the D2 is mostly used as a normal power station and only to a very small extent as UPS. Especially because switching time isn't really great. In order not to make life unnecessarily difficult for the user, it should be possible to set the desired functionality via app
Did you measure how much power it draws from the wall when its batteries are charged and no load (or a light load like 100W) is connected ? I've read that for that kind of use (EPS mode) it is very wasteful... Is it true?
I just tested this out for you, it pulls about 9.4 watts to be on with the AC inverter on. Not super wasteful but I bet it's less efficient than a true UPS.
Spare battery has no other input nor output? You can't independently charge it without the main unit????? That is lame. That is really really disappointing. Why can they do what Bluetti has been doing?
My guess is that they're trying to hit a price-point by not adding the DC regulator and circuit board needed for input/output of DC and they'd also need an internal AC charger to charge it separately. I can see on a product in this price range why they don't have the wall charging ability as that also creates the need for fans and venting and would probably take away from the storage bin, but the DC in/out would have been very nice to have I agree with you.

Returning the Anker 757 as the solar xt60 cable has to be unplugged at night and replugged in the morning and press the display button to get it to accept solar on sunrise. 🤷. I've ordered the UK Delta 2 and the additional battery. I hope it lives up to your review
I hope it does too. I haven't tested that with the Delta 2 but you can program it to not shut off so in theory when sun start producing energy in the morning it should automatically start taking off once voltage comes up enough. Let me know how it works out for you.
Hello Jason, question for you or your community. I have the delta 2, with backup delta 2 battery (1800W Output/2700W Peak). I am testing out in a home refridge which, when running, is pulling ~173 watts. When not running, pulls zero watts. After five hours the units (both D2 and backup D2) beeped and turned off. No surge, just tuned off. Is it plausible that the absence of wattage draw when fridge is idle caused the unit to shut down? I re-read the manual and didn't see an obvious caution, but am guessing. Maybe I need to connect anything that draws some type of wattage to keep this from happening?
I may be able to help you but I don't have enough info, when you turned the Delta back on was the battery dead or not? If not then it maybe timed out, you can login to the app and change AC power to never turn off. If it was completely dead then you may have an issue with the BMS and battery balance, contact Ecoflow. I'm unclear on if you have two Delta 2's or a Delta 2 and Delta 2 spare battery, but w/ a Delta 2 and spare battery I'd expect you to get about 14 hours from the fridge factoring in AC inverter loss and idle consumption. Half that for just the Delta 2.
@@reviews2you Hello Jason, I think I figured it out. First, to answer your question. I have the Delta 2 and Delta 2 backup battery. They are connected together and both powered on and both at 100% when running the fridge test. As stated, 5.5 hours in, they beeped and powered off. When I turned them back on, the primary was 82% and backup 73%. I also had it set to AC power as recommended. As it turns out, the online owners manual states the default shut off is 2 hours, meaning if there’s no power draw, it turns off. I checked today, and the Ecoflow app states the default auto-turnoff is 30 minutes (for both DC and AC). I assumed when running the test there’s no way a fridge’s compressor would not kick in during a 2 hour window, and assumed incorrectly. As it turns out, it exceeded 30 minutes easy. With that in mind, I am re-running the test with the defaults set at 30minutes. Thanks for replying so quickly!
Quick follow-up: I re-ran the test with the Delta 2 and backup battery (D2) with idle shut-off set for 2 hours (vs 30 minutes from the first time). It lasted well past 10 hours and only flipped back to utility power as I was heading to bed. Many hours left in reserve. I ran other tests with tvs/modems/gateways, etc., and between all tests (including the above) noticed a ~ 20% reserve variance between the primary/slave batteries. I 'read' they charge and discharge at an equal rate, but I haven't seen this. I just bought a delta 2 max to add an additional reserve battery for extended outages. Great system! Thanks again for your reply and input.
@@theociba3762 I'm glad it worked out! Spare battery and main unit should ideally stay within about ~10%. You can run them both to 0% then charge back to 100% and I bet they stay closer next time. If you haven't, feel free to subscribe for more content that's similar. thanks
Hello, I now have 2 solar panels of 150W, 12V Poly (facing South) and use them straight into my Ecoflow Delta 2. I notice that with that, and when Sun is out on the panels, I can charge the Delta 2 to full in well under 3h. I do get shading on the panels during the afternoon and the power drops significantly to only 40Watt. I bought 1 extra solar panel 150W, 12V Mono (facing South-West) and put all 3 in series. Dilemma ; As I only use a relative small percentage of my panels, because I only use it to charge the Delta 2 power station, I would like to benift more from it to have more off grid power and wonder what to do. What's best system wise and what's best budget wise. Do I buy the special extra Delta 2 battery from Ecoflow OR do I go for a DIY setup ? The Extra battery from Ecoflow is at 800,ooEuro and gives an extra 1024Wh but needs to be charged by the Delta 2 itself as it can not be charged or used by itself. The other DIY way has different options but comes at about the same cost for a little more power. As with the extra Delta 2 battery there is no need to buy anything else, no solar regulators, no 12V to 220V converter. On the other hand, with the DIY setup I do need 2x MPPT regulator (take 2x 100,ooEuro) , a 12V 100Ah LiFepo battery (around 500,ooEuro) and a 3000W pure sine converter (around 350,ooEuro) plus wires, fuses etc. (Comes easily at 1000,ooEuro) (And then better put a 4th solar panel of 150W 12V MONO, to balance and have 2x2 panels. I also looked at the GroWatt all in one but that asks for more panels (for minimum requirement start working voltage) That would be a nice system but even more expensive due to extra panels plus I only can put 6 panels (3x2 in slightly different orientation) due to space.
I solved the problem of having more solar then my Ecoflow can take by using an external battery(100 Ah LFP with heatmats as it is located outside my house) where my solar is dumped. When I see the external is getting full I turn off the AC-in of the EcoFlow battery's I have and they get charged from the solar. That likely means some losses but will also give solar a battery to go when the EcoFlows are full. The external battery is charged with Victron MPPT's that have a load port that can be programmed to shut off when voltage is low, thereby protecting the external battery from getting discharged to much. Ecoflows are set to charge to 95% SOC which is respected both when AC charging as when DC charging........ In that case the electricity can stay in the external battery.
@@ronaldstowell4368 Yes you are, I cover it in the video but you can direct connect w/ bluetooth, no internet connection needed. But if you want to operate it away from home you need the internet, in that case just have the D2 run the router/modem in UPS mode in case power goes out.
@@reviews2you Thanks Jason. That moves the D2 to the top of my list. My only wish is that the second battery could be charged independently. Not a deal breaker, but it would be a bonus. I like to leave my fridge in the truck overnight when traveling and being able to take the second battery inside to charge overnight without interrupting the power supply would be great!
I haven't reviewed it but just glancing at it I don't see a single area where it would be better. And for the chemistry they say "lithium-IRON". What is that? Did they mean Lithium Ion? Lithium iron phosphate? Probably the latter based on 2,500 cycles to 80%. Heavier, less capacity, slower charging, more expensive. Not sure I'm seeing any benefits other than the word Patriot is nice. :)
I don't know their testing parameters but I highly doubt it. Best practices are to not fast charge but the option is there if you need it. Once in awhile won't hurt it, but constantly charge at full speed will reduce the battery life and puts strain on the charger and other components.
@reviews2you thanks for reply!. Question for ya, I read a review that said there was an issue when using both the delta 2 and the extra battery. The issue was that the delta 2 power station would drain substantially faster than the delta 2 extra battery. He noted sometimes even upward of 15 percent. Like the delta 2 would die and the extra battery would have 15% left in it. What's ur experience?
@@Juan1985g Hey Juan, they can vary up to 10% per manufacture. With mine they stay pretty close, usually within 5% or so. That percentage isn't an exact amount. You may need to cell balance once in awhile.
I was having issues with my River Pro w/ spare battery not being recognized and told them after 2 rounds of getting bad units I was going to have to return it. They apologized for the problems and asked if I wanted to try their new Delta 2 as they had a few ready for early purchase, they sent me an amazon link to pick it up ahead of time.
Hello, how do you mean more power? Push more than 1,800w from one unit? No. But you would have the full 1,800w with each. There is no benefit in connecting them. You could feed power from one to another, but you can do the same with a spare battery and that's cheaper. If I didn't understand your question correctly let me know and I'll try again.
Yes, more power, more Watt available to power a bigger load. I would use the Delta 2 in my mini camper time to time (maybe 10, maximum 20 times a year) but mainly as an off grid power (all year round) in a cabin. . I now have 2 solar panels of 150W, 12V Poly (facing South) and use them straight into my Ecoflow Delta 2.

Thanks, I just ordered a Delta max with a Delta 2 , instead of an extra battery. An idea I had seems to be real, in the form of next year's Ecoflow 'Ultra'. Batteries and the inverter/controls, are separate units all together! May be the tech will trickle down to smaller units. 240v would be nice in a smaller 15 ish amp unit, too. 3/4 hsp / 8 amp deep well pumps, are everywhere here. Most have starter capicators and do not have a huge starter draw. I run every thing, but a 240 hot water heater, easily on a Honda 35000. It's a; thrifty, trouble free, clean sine wave unit. Pull start is getting old!
@@christophergallagher531 Yeah I wound up buying a Max 2 w/ a Max 2 spare battery and kept the Detla 2 which can use the Max 2 spare battery. This configuration gives me a lot of flexibility. The industry is moving very quickly, as these are much better than devices we could get just a handful of years ago. We may very well start seeing split phase 240v in more mobile units in the coming years. The Ultra is enticing, I haven't had a chance to check it out. I went a different direction w/ my home backup and will be covering that in a future video.
It is happening fast. I gave up on the delta pro set up, looking at the advances coming. I really have research panels, and get the ball rolling. Looking forward to your reviews.
What happened? I have had good luck with Ecoflow's customer service but they are overseas so they tend to respond in the middle of the night and you can't easily get anyone on the phone it's all email based.
@@reviews2you it's all over paying full price and no 5 % discount code which left a bad taste but the charge for a £70 case and not receiving the free one. The complete arrogance of saying one thing and failing to follow through with a refund and now the total blanking of emails which have been polite. If this is how they behave with customer service, It concerns me that any warranty support I may need on a package I paid nearly £2k for, will be non existent.
@@under2boots I'm sorry to hear that. You probably aren't interested in them at all anymore but I just posted a new deal under the comments, $100 off the main unit and another $100 off the spare battery if you want to return yours and order that one. The discount is immediate so you don't have to wait on a rebate or money back etc. Sorry for your experience, so far they've been good about getting back to me but can take up to 2 business days I've found.
It depends on what you're comparing it to. It's not louder than my Bluetti EB70S, it is louder than the new Ecoflow River 2 Max. They did just roll out a firmware upgrade to the River 2 since I did the review that vastly improved the features (automation etc) and it seems like it may of quieted it down or I just got used to it. It's really not that bad, but not noticeable. I'm not brand loyal, I have Ecoflow, Jackery, Bluetti, Rockpals etc and this Delta 2 is my favorite one as of the time of this comment for what it's worth.
@@013gaston I have a jackery 1000 too. External power brick that gets very hot, slow charge, NCM battery chemistry, no app etc. No comparison to the River 2 IMO.
@@reviews2you I do agree ...that is why i want to change for the ecoflow Delta 2 . The only thing i do not like is when it is charging it is very loud . Because i live in my van , most of the time i will go to a Tim Horton ( or other restaurents) to charge my battery.... So if i try to charge my Delta 2 , the noise may disturb other poeple near me...........But I do agree that the Delta 2 is way better than my Jackery ............Thanks and my regards
I understand. They just updated the app and in the AC customized charging section there is a selection for "Quiet Charging". I had't tried it yet since the software was just updated so gave it a quick try for you, had it charging for ~5 minutes and absolutely zero noise when in Quiet charging mode. Perhaps a fan will kick on in a bit if he heats up but as of now it's charging at 212w and zero fan noise. Hope that helps
Ecoflow have been appalling for me. I cancelled the transaction and there has been no communication from them for a refund. They have withheld the money for no reason. I live in the UK and every place I see this companies products reminds me how bad the customer service is. Great for content providers.....a disappointment for those of us that make the unfortunate decision to get involved with them.
I'm not a pawn for any company, but honestly out of all of them (except maybe Jackery) they have been the best. Send an email to support@ecoflow.com or login to their facebook group and post publicly on there, they jump on stuff quick. Sucks you had a bad experience and thanks for letting us know, follow back up later with how it came out.
They have been a good company for me too sicne I discovered them and anker too. I love my delta 2,river 2 and river pro I have from eccoflow and my anker powerhouse 555 and 757 too.
The 3000 charge cycles is what got me interested in the Delta 2.
I think there is a lot to like, but that is a big one for me too. You can use it daily and know you'll want something else well before it wears out.
and the reduced fire risk of lifepo4. Don't want anything else then lifepo4 inside my home until better tech comes along.
I've had my pair of this model for just a few days and have gotten accustomed to it and thank the designers for the features it was built with.
I do plan to look around more for cons so I do not get blind sided by any of them since "cons" are few and far between the "pros" reported by useres.
Thanks for your review!!
Thanks for taking the time to watch. Definitely spend time getting to know how to use it so when the time comes you can put your effort into other things and not learning the generator. Also, I've found if they're going to fail they typically do it early on so use the heck out of it for the first month or two and get to know it and battle test it. I will have more content coming soon if you want to subscribe.
@@reviews2you I have mine currently powering two ACO POWER 50X 12v Dc Fridge/Freezers to gather how long both can run on ECO battery alone.
I read the manual and noted the fine points. You covered then all - good pace and detail.
I bought the D2 + battery effectively doubling the power. I see there's the larger backup battery (~ 2K?). I don't plan on going off grid, but my hope is to run a lcd TV, modem, light and heating blanket if the power cuts in winter. Something tells me these are more than enough to do this.
I tried to come up with a condescending remark, but I couldn't come up with one. This is an excellent review on a very good product. Your suggested improvements for the Delta 2 are spot on.
Haha, thanks a ton!
Pretty sweet review of the Delta 2. The 1kWh capacity is more than what I need for my CPAP machine.
Sorry for the delay in my reply, youtube had your comment held for review for some reason and I'd missed it. I agree, this should last a long time on your CPAP! You should report back after you have some time with it, and let us know how long it lasts. I'm betting 3 nights worth, or more. If you have the DC plug for your CPAP you should try it and the AC plug and see which you get more use from, that would be interesting. Thanks for watching!
Great review ! I have the River Max and Delta Mini . Love EcoFlow products plus I subscribed to the channel. Thanks
Appreciate it!
Thank you for the review. You just made me realize how good the new Delta 2 is especially with the option to connect an extra battery. .
I agree! And don't forget you can connect the 1kWh Delta 2 spare battery or the Delta Max 2kWh battery!
The expandability of the Delta 2 is what I really need. I can max out to 3kWh whenever I need to.
Yes! Just keep in mind the 2kWh expandable battery from the Delta Max is NCM chemistry with a shorter lifespan than the spare battery (and main battery) on the Delta 2. My guess is by this time next year they've replaced most of their line with LFP battery chemistry so if you don't already have a Delta Max battery it may be wise to hang on for a bit!
@@reviews2you still waiting for exhact same thing
33:47. Oh it's a **LOT** more than a doubling in cycle count. Jeff Dahn (one of the world's foremost experts in battery chemistry) has shown that if you keep LFP within its sweet spot there is no measurable degradation. The sweet spot being between 80% and 50%. Of course, that's a pretty small window, but if you were to say keep it between 85% and 30% your cycle count is probably 10x that of fully cycling the cells. Basically the closer you stay to the sweet spot, the less wear you put on the cells. Also, the less amount of time you spend outside of the sweet spot the better. (Bad, bad, bad, to completely discharge a battery, and then to store it like that for instance.)
These usage guidelines hold true for regular NCM and NCA chemistries as well, just more damage is done as you cycle the cell, and you probably aren't going to avoid wear altogether (though you can seriously cut it down).
Yep. I typically do a couple full charges and discharges to program the BMS and test to make sure full capacity is there, then after testing and reviews I set them to run from 30%-90%. Prowse says there is no need as you'll likely calendar age them first and he's probably right, but I'm conservative and still do that when I can.
I am surprised that Ecoflow was able to make the Delta 2 charge faster. A full charge in 80 minutes is out of this world.
I agree! That charges as fast as my iPhone and it has a large 1kWh battery bank. Makes it so much more usable and the reason I grab it over my powerstations that take 5+ hours to recharge.
You probably also remember that all quick charging and quick discharging shortens the life of the battery. So it's not worth charging with 1200W power and discharging with 1800W power just because you can do that.
I just got a full charge in 50mins
After watching the review. I would definitely buy it since it charges faster than any other power station.
The charging speed is huge, thanks for watching!
Great stuff! I may go ahead and order the Delta 2!
I was in the market for an original Delta!
Glad it helped you to differentiate! I still think the OG Delta is a good unit, but unless it's significantly less I think your money is better spent on the 2.
I finally purchased one today... power went out last night for 90 minutes, my UPS kept my TV on ECO mode and cable box on consuming 40w, still had about 40 minutes left on UPS when power came back....
I'm glad the power wasn't out longer. I hope you're happy with it. Let us know what you learn
Xboost is something you by all means try to avoid using, but if you absolutely have no alternative it comes in handly.
It lower the voltage so the receiving device will be satisfied regarding amps, like you explained at 35:20 and 38:20. Not all devices will function with a lower voltage though, so use only when absolutely needed. So yes, Ecoflow should as a default have it turned off!
So xboost is not really outputting 2200 watt (Amps times voltage) but when it is on it can deal with devices that normally would require 2200 watt (or 10 or 20 amps depending on where you live).
It is also not like peak performance as that will last much shorter then xboost. Xboost is for running a high amp thirsty device for longer periods.
Basicly if you have a device that wants a lot's of amps and it not very pickly on the voltage, you might get away with it. Think resistive heating, large electric motors etc.
Typicly you use it for one device at a time.
Do not use it to run multiple devices that total more then 1800 watt.
And do not use it when powered into AC at the input side :-) I believe Ecoflow blocked that anyway.
Yep you got it. It's a good advanced user tool and as such I'm glad it's there, but it seems like something that would create more problems for users and their support than it helps.
@@reviews2you
I say it is only for people that know what they are doing or have enough money to risk breaking it.
Meanwhile I am a bit in doubt about the fan-noise.
When running on or charging the battery I am fine with the fan-noise, when running on AC(in) it shows this does not have a transfer switch but does AC->DC->AC. Which not only is noisy but also inefficient.
That is why I installed a real transfer switch at home which uses the Delta 2 as generator in case the grid goes down.
@@HansKeesom It sounds like you have a pretty great setup. I noticed since my review the fans have gotten less noisy from firmware upgrades. They clearly reduced the RPM under certain conditions.
Thank you
The LFP battery is the deciding factor for me. That translates to more than 10 years of daily usage.
100%. Plus I have small kids and pets in the house, for me the extra safety is worth the price of admission alone.
@@reviews2you Absolutely, for AA it is fine to have NMC but once you get to hundreds of wH I like to reduce firerisk.
My official Shimano e-bike batteries of 410 and 500 wH are kept in a fireproof bag, just in case they go off
@@HansKeesom Smart man
Since I already have the Delta Max extra battery. It's good to see that I can still use with the new Delta 2.
Yes, sir! Just keep in mind it is different chemistry and will degrade a bit faster, but if you already have it then heck yes, that's perfect for you and it should increase the efficiency of the inverter by having a larger battery bank.
Just ordered one with the solar panels. Couldn’t find long extension cables for the panels but I heard you can get 50 footers.
I subbed
Yeah you'll want at least 10 AWG. Try and keep voltage high and amps low otherwise you'll have a decent power loss over that length: amzn.to/42tvt21
Voilà la meilleure expertise que j’ai pu voir sur RUclips de cette batterie !
Merci!
Great review..
this delta 2 is like a darn roller coaster.. it has a lfp battery 👍🏻, can’t dual charge👎🏻, Is expandable👍🏻, only 1kwh in lfp or 2 in nmc 👎🏻, price is pretty good👍🏻.. you get the point.
At some point, someone will come up with a hack on that extension I’m guessing, that can run like a 48v battery. You can do it with the solar input, but 500 watts and it won’t charge kinda sucks.
Only other thing I wish would be that it work with the ecoflow smart generator, that is a pretty neat system that has some benefits.
Thanks and I agree with your take away. The dual charge thing is a bit of a bummer. I'm not sure how many people would actually do that, but it would be nice to have. I'm willing to bet they revamp the Delta Max w/ LFP and it will have more expandability. Overall they still keep getting better each year. I just got a new River 2 Max and it's much better than the last generation (including app features). Still a long ways to go, but compared to what we had to choose from 3 years ago this industry has come a long ways, and Ecoflow is one of the top companies driving this evolution (Bluetti too). Thanks for taking time to watch my video.
@@reviews2you yeah, I was looking at the river 2 pro (but it was out of stock) it has great features for the price. I liked the max too, but wasn't quite big enough. Just picked up the delta 2 and 220w panel on amazon for cyber monday deal for 1099, which is an amazing deal.. I decided to wait on the extended battery to see if they make a extended 2+kwh battery thats lfp..
@@jmac1099 The new River 2 Pro isn't out yet, they have had some issues with production or the unit, unclear which. It doesn't have the expandable battery that the current River Pro has, which I have. I think a good combo is either the Bluetti EB3A or the Ecoflow River 2 Max for small then the Delta 2 for a good mid sized unit then Bluetti AC500 for a large unit. I have all of them, I'll get more reviews and comparison up at some point.
@@reviews2you ah.. funny they just said out of stock, but that totally makes sense.. well I’ll be waiting to see some more from you..
The dual charge I solved with an external battery(100 Ah LFP with heatmats as it is located outside my house) where my solar is dumped.
When I see the external is getting full I turn off the AC-in of the EcoFlow battery's I have and they get charged from the solar. That likely means some losses but will also give solar a battery to go when the EcoFlows are full.
The external battery is charged with Victron MPPT's that have a load port that can be programmed to shut off when voltage is low, thereby protecting the external battery from getting discharged to much.
Ecoflows are set to charge to 95% SOC which is respected both when AC charging as when DC charging........ In that case the electricity can stay in the external battery
2 in nmc is no negative for me because nmc is a no-go for me :-)
Was very happy with my new Ecoflow 2000, although concerned about the battery cycle life, Unhappy with the deal, paid the top then price in South Africa, the new Ecoflow 2 came out the following week without warning and 20% cheaper for 5 times battery cycles, a big factor when power is down 25% of the time.
Sounds frustrating, all the best.

Sorry for the delay in my reply, youtube had your comment held for review for some reason and I'd missed it. Yeah as long as you don't exceed the output limitations you should be good. You can even use a power strip with it even though they may advise against it, I've been successful with that. Or a USB C to USB hub ;)
Excellent review and what are you doing with all those powerstations?! Well, I'm just like you; I have a few myself and getting more, including this Ecoflow Delta 2 unit. Have you looked at the Pecron 2000LFP?
Thanks, Jason! I just like to tinker with them, I often sell them and replace with newer units as the market is flooded with new battery generators these days. I'm in the process of building an off grid backup system with server rack batteries now. Sold my Battleborn batteries and going with some rack batteries, I may do a video after I have it up and running.
I have checked out the Pecron but haven't tested it yet. I may get my hands on one here in the next couple months, on paper and from what I've seen it seems like a solid choice.
The cable placement and length allows for placement in a place that doesn't allow for the stacked height.
That's true, but no reason to not put the cable ports in the back. I think their engineers were crunched for time :)
So the ac inverter is like 12-13% more efficient than straight thru dc? That seems to be just the opposite of what I had always heard was the usual case. Is that also true for the Delta 1300? I have a Delta1300 now and have used it to power my 12v fridge (Alpicool T50) on camping trips, but always in dc mode thinking that was more efficient. The fridge can also run on ac and I guess if I buy the Delta 2, that should be my new default. Any comments Jason?
Yes that's right. It's a common misconception that there is no (or less) loss with DC which is understandable since the battery generator has its' energy stored in DC. However, keep in mind that battery pack is 51.2v so to get it to 12v you have to step it down with a regulator and there is loss in that. It is actually common that DC output is less efficient than AC. Now if you have a no regulator and an internal pack with a lower voltage range you would get more from the battery pack but then as the battery SOC reduced the voltage would reduce and items like your fridge would shut off.
I had the same question as you regarding the fridge. The short answer is I don't know for certain, and each fridge will vary with that. The reason is because your motor in the fridge is DC therefore it will have to convert the incoming AC to DC to power it and you'll have loss there, which may more than make up for the gain you'd get from the Delta 2 AC efficiency out. What you would have to do is charge the unit to 100% and run the fridge for a set amount of time and note the percentage battery drop on DC. Then charge it again to 100% and run it for the same amount of time on AC and note the battery drop.
Your Delta 1300 has an AC efficiency of 83% and DC efficiency of 65% so in either case you're better off with the Delta 2. If you do the test I'd mentioned above, come back and leave the results, I'd be interested to see. My guess is that it's very similar either way.
very nice detailed review
Thank you!
Great review, one of the best out there!
Thank you!
Thanks for the coupon. I will use it to get my Delta 2.
Sorry for the delay in my reply, youtube had your comment held for review for some reason and I'd missed it! Thanks a million for using the link and glad it saved you a bit of money. Let me know what you think of it!
I believe they removed the fast/slow switch from the back because the delta 2 has Bluetooth where as the delta only had WiFi it’s a pain to connect just to change one setting when you are not at home you have your connect to the deltas internal WiFi hot spot which once you connect it shuts off your phones mobile data making your phone useless until you disconnect
The Delta didn't have any connectivity but the Delta 2 has WiFi and Bluetooth and you can adjust the input setting via the app. Would be cool to have a manual switch still on the back for when you didn't have app access (phone dead, not handy while camping etc). In any case, all this time later this is still a great device. Thx for stopping by.
@@reviews2you Yea I will alway prefer a switch over the app I hope they add an inverter on/off switch on the front of the next delta I have the max pushed into a cubby hole in my van so I can’t reach it I have to connect to the deltas wifi network every time I want to switch the mains on
@@reviews2you15:59
I noticed at the end of your video the time left on the main unit was glitching. Going from 98hrs to 79 then 83 then back to 98. I bought the complete kit. The main unit and back up battery with solar panels and water resistant case. Found out it wasn’t enough power for my needs. And wanted to send it back in trade for their largest unit. They’re going to charge me a restocking fee as well as shipping fee. Total for all fees is 231 dollars. Not happy about that.
Interesting, I hadn't noticed that about the battery remaining time moving around until you'd mentioned it. This was an early production unit and they have released a firmware update, I'll have to pay attention on if it still does this. They did make some improvements since I did the review. You can now do silent charging, whereas I hit them a little bit for the noisy charging. I'm not sure what your needs are, but you can check out the Bluetti AC300 and AC500 if you need something much bigger. I prefer those over the Delta Pro because the PV input is greater.
Thanks for the reply back. I’m a newbie with this stuff. So wasn’t really sure myself. But 1800w isn’t enough. Seen the price of it and what it came with and figured that was a good deal. And took the chance and bought it. Then found out not enough watts. The others are really expensive for me. I decided to just keep the unit and put it threw it’s paces. I live off grid and was trying to give my diesel generator a break from time to time as well give my wallet a break lol. Maybe something other than solar generators would be better for me. 🤷🏻♂️
Amazon sells some nice 10" pigtail cord extensions
You mean the Y adapters? If so I just added a link to them, thanks!
I prefer 2 delta2 than the extra battery .
Yeah a fair amount of people feel this way. Glad you found a way to make it work for you.
Hey Jason thanks for your content my question is what’s the best way to wire this unit to a 12v fuse block panel? After looking over the unit the 12 volt cigarette plug is not the most reliable connection for the 12v fridge I have in my van. Thanks 😊
Hey There - you could take a 12v out cig lighter cable and cut the ends and run them into your fuse block or take it from 110v AC side w/ a step down converter but that would be less efficient. I use temperature monitors in my freezers that notify me if the temp climbs which would be a good way to tell if something had come unplugged or shut off.
Good review I have the river pro and about to buy the delta2 one thing no one is mentioning is if you get the smart generator it would only be able to charge the main unit as it plugs into the plug the additional battery plugs into .. I'm guessing eco flow will release the Delta Max 2 in the new year with lifepo4 battery and increased solar input
Thank you. Yes it's too bad the spare battery doesn't have a second port so you could daisy chain the smart generator and the spare battery also needs DC output IMO. As a bonus having it's own XT60 input for car/solar charging would be nice. Bluetti does this on their higher end units. However, compared to the River Pro (I have it w/ the spare battery too) the Delta 2 is much better. They also updated the app since my review adding functionality including silent charging. $899 is the cheapest I've seen it and if you email Ecoflow you may be able to talk them in to sending you a free cover. I was able to get one and it's actually pretty nice. Enjoy! amzn.to/3BpPE54
@@reviews2you Yes, a xt60 on the external battery would be nice so you can charge it while away with the main unit or even charge an array of external battery's and use any of them when needed..... and transfer power to the main unit....
Wondering if we can connect a MPPT controller to the connector of the cable. I believe 48 volt is on it and if that is directly connected to the battery.......
I have the river pro from kickstart with the EF-1500 battery. That battery is super. I use it in car to keep my cooler running for days while charging it while driving for sigarette lighter and from solar when not. It is a beast.
And during these trips the River Pro can easily stay at home doing it's normal function keeping my internet up and running.
I can use the 24 port of the EF-1500 to charge the main unit. Do use have a 24/24 DC for that..... as the voltage on the poles the higher then the input of the R600 can take ;-)
@@HansKeesom It's a good question. You may be able to hack it to get a charge controller to feed the spare battery. I have enough other battery generators that I wouldn't risk it as I could just grab a larger unit if I really cared but I like the question and ingenuity.
about the cable maybe the creators wanted for us to have a clear space for safety and cooling.. not only it needs space for air circulation but if you have a visible cable to have some time and store it correctly you will be aware and no destroy or kick it in accident!!!! as long as the fans are at same sides and opposite. then for sure its strategic trick that extra battery cables to go that way!!!!... prove me wrong. !!! so. what if that cable was in better possition and many of us wouldnt even care to take it out of small spaces so it operates in better place and have better cooling!!! only possible update in any future delta 3 for extra battery possitioning is to have the fans AND the cables front and rear .. but even then the rear has to be far from walls ...
That's not the case as proven by the latest generation of battery generators that are now stackable per us reviewers critique.
Great review! Keep it up.
Thanks, will do!
Great video thank you. What would you recommend to keep charge at when storing for an extended period of time? I’ve been reading contradicting recommendations
Thank you. I believe if you read the manual it may say, and I think they say around 60%? However, I store all of mine at 80%. My thinking is that it's not left full so it isn't hard on the cells and has enough charge that if something happens where I need it then it still will have a good bit of power left.
For best practices I recommend every 4 months to cycle them a little. I'll transfer energy from one to the next, charging them down some and then back up to 80%. Keeps the cells healthy this way. I also spend that time to update firmware and ensure everything is still working properly.
@@reviews2you appreciate you
You can not connect the Ecoflow Wave 2 if you have the Delta 2 and extra battery connected, the main battery needs another connection.
I never said you could. You'd need the Max, Max 2 or Delta Pro for that.
Looking forward to more . .
Thank you, more on the way for sure!
I think the reason to charge slower the last 1%, to protect the battery.. my Bluetti does the same. Maybe I’m wrong.
Yeah it has to charge more slowly as it reaches peak voltage, that's normal. Still far more watt hours appear to go in at that last little than proportionally should. I suspect it's to make it look like you hit 80% faster but I could be wrong. In either case it charges great and has been a great unit.
Have you tested the Delta Pro? And how does it compare? Thanks.
I have a buddy that uses two of them w/ a smart home panel but haven't tested one directly. New Delta 2 Max review coming up. Current Delta Pro is much larger and heavier. It's a good unit but the solar input is limited IMO. I predict they should have a new Delta 2 Pro out in the next few months so I'll hopefully get my hands on one of those. Subscribe to be notified.
Will EcoFlow app send a push notification when the battery reaches a low state of charge?
No but you can set it to shut off at a certain low state of charge. That is a good recommendation to make to them, though. They did just add some automation in the update that rolled out this week allowing you to set charge/discharge times as well as prioritizing solar charging and the biggest one is to automatically turn on the AC inverter when the machine wakes up. So if it does but is plugged in to solar as soon as the sun comes out and it starts to charge the system and AC inverter will turn on which is huge.
thx ❤
For just 200 more why wouldn’t you just buy two units instead of paying 800 for just a spare battery alone?
In addition to the price savings, the main unit can manage the charge/discharge of the extra battery, it cannot do that with a secondary main unit.
@@reviews2you it doesn’t need to manage a battery, the second unit can manage itself; moreover one would gain the advantage of twice the receptacles, the ability to use it in separate rooms, have the same amount of power and best of all can be charged individually.
@@danielvazquez7482 So if you want to run a load unsupervised and it will require ~2kWh how will you manage those two main units?
@@reviews2you Honestly, if you had to run 2kWh “continuously” would this really be a reasonable option? Besides the cooling fans cranking overtime, once it’s depleted (which won’t take long) you’ll then need a couple of hours for it to cool down before it will except any charge. Try it.
@@danielvazquez7482 I didn't say 2kWh continuously, you did. I understand fully what you're saying but you're not getting me. This makes one big battery that will be managed by one BMS, your proposal wouldn't work in the same way but if that's best for your needs then that's exactly what you should do. Thanks for watching
These Fancy Box's are sure not affordable to most people unless a Loan is taken out.
I'll keep using My Deep Cycle Batteries and a good inverter. (My 12vdc Stuff runs great off the deep Cycle Batteries)
It would be hard to duplicate all this can do for the price in my opinion. You can only discharge a deep cycle to 50%, these you can discharge to 100% so you'd need two deep cycle batteries to equal the capacity one of these batteries can do, so right there you're sitting at $400, then a fairly junky 1,800w inverter will run you $120, then you have a high power battery charger capable of 1,500w charger. so on your 12v system that would be a 125 amp charger, that would run you several hundred but let's say you forwent the ability to charge fast and just got a $70 20a charger. Then you need a solar charge controller capable of 500w which is $130. Then you need a DC regulator at $40 then you need your usb/5521/cig lighter ports, at least another $50 if you can even find all of that. You're already over $800 and you have a massively heavy system that can't easily be moved and is inferior to the specs that's all in one here. Plus you don't have mobile app access or simple expandability.
@@reviews2you I already have all that stuff. No need to buy any more.
My 3,000 watt Pure Sinewave inverter was Free. HEHE Most of My equipment is 12Vdc anyway..
2 8D deep Cycle batteries in the back of My truck can run stuff for week or more.
The only new stuff I've added to My equipment is 400 watts of Solar charging.
When I camp, Power is the last thing I think about. It is a luxury more than a necessity.
I'll take My phone and leave it turned off
or just plug it into the Truck which has 2 batteries of it's own.
Well you're a unique case, most people don't get free equipment. :) I'm glad what you have works well for you. Thanks for watching
Great review from the UK, looking at buying this unit with the additional battery but I have a test/query for you, in the UK we have off peak electric so would the unit charge on solar during the day and set a mains timeclock on for sundown to buffer charge though the night? I am running a fridge in my summerhouse. Will the unit switch automatically through the cycle I mention? Thanks
Thank you. If I understand your question correctly you're asking if you can leave it plugged in to solar and and the wall at the same time and get it to just charge from solar during the day and the grid at night, is this right? If so, the short answer is no but I think there could be a work around. If you have it plugged in to the wall it will pull electricity but you could get a timer and plug the Delta 2 into the timer box then the timer into the wall and set it to kick on only during the hours you want it to charge from the wall. I think that should solve your problem. Good luck
@@reviews2you Yes thats correct I will use a wall timer to click on grid at night so the fridge/freezer works throughout the night. It was more a query as to the automation of the EcoFlow as once set up would it just cycle day and night like indicated without turning anything on say once the grid clicks on at night? Thanks for the reply.
Is it possible for a couple hundred dollars more just to buy another main unit and use it as a battery as well. Seems to have way more benefits?
Yes and no. You could use one unit to charge another via AC output on one but you wouldn't have a master/slave situation like you do w/ a spare battery where it can charge/discharge from one cable between the two units. The benefit of two main units is if one unit breaks you have one to use still, whereas if the main unit breaks and you have a spare battery only, you're out of luck.
Also, w/ two main units you'd have double the solar input, but it just depends on how you'd use it whether it makes sense or not. If you plan to leave it unattended and want it to charge from solar and discharge to a load automatically that will be much more challenging to do with two main units. If you will always be nearby to manage them then buying two main units may make more sense.
@@reviews2you thank you
EcoFlow units are so popular that the company doesn't offer real discounts with the exception of old tech...
They have $100 off the River 2 right now and if you spend over $3k you get a free River. $899 for the River 2 is 87 cents a watt hour, that's cheap for what you're getting. amzn.to/3AIfz7I
@@reviews2you Yes, a great bargain for the "smaller" units, not to be sniffed at.
If I hook them up in tandem. Is there an adapter to plug it into a generator port/switch and run 220? I would like to run my well pump to get water.
No this is 120v only, there is no way to run a 240v appliance with this. All the extra battery will do is extend your capacity but it won't change the inverter output voltage. If you need 240V from Ecoflow you can get two of their Delta Pros and you can link those together for split phase 240V. You can also do this with the Bluetti AC300 (and I think AC200 but you need to confirm that). Also, the Bluetti AC500 is on indigogo now for crowdsourcing at a pretty good discount. Two of those will run a split phase 240V load up to 10,000 watts. You can find the limited time special on the AC500 here: ac500-b300s-super-capacity.kckb.st/c8ba398a
So, these things are intended for powering small electronic devices, is that right? They're not for household lighting, wall outlets, etc, correct??
This isn't designed to power your house, it's designed to power anything you could plug into your wall as well as DC items. I will be doing a review on this one coming up, but if you want something that can work as a home backup you could get something like this and plug in to a transfer switch. Just note it's for 120v only, not 240v. Also you may need more batteries, it can run up to 6. It's not my favorite home backup option but if you want something plug and play it's half off right now which makes it a pretty good deal: amzn.to/46EeZ9G
This one has 240v and 120v, but note you can only run one at a time but if you're feeding a transfer switch it can work. There are much more capable units but price starts going way up, not sure what you're aiming for. amzn.to/4cmN2on
Can a timer be set up to recharge. My power company is free after 8pm
It's a good question and the simple answer is no, they don't have charge timer options in app but you could get a smart plug like these and set them to turn on and off at certain times.
amzn.to/3MjoG3a
The instructions say not to connect them with the power on…I think.
That's right. I haven't had an issue w/ this unit, but have with their old River Pros in doing that.
😊
Just in general how long would this run a fridge that is 6 amps, 115 volts and 6 Hertzs? If I added the extra battery? I know you can not say exactly so just an educated guess. Thank you awesome very through review!
Hey John, if you're pulling a full 6 amps the whole time (not just the peak start up number) then you'd only get about an hour and 15 minutes off the main unit, double with the spare battery. But usually refridgerators pull a lot to start then drop way down, averaging more like 100w/hr. In that case you'd get more like 8 hours off the main unit, and double that with the spare battery.
@@reviews2you Thank you. Thats workable in a blackout considering you can charge with solar as you use it.
@@johnmal5975 Yeah if you have the spare battery with the main unit and enough solar you should have more than enough energy to perpetually run a refrigerator. Just make sure you stay within 60V max for the string of solar panels. It can accept up to 500W so with the main unit and spare battery if you can make even around 400w that's 5-6 hours to fully charge both batteries.
Thanks for this, how did you get this before release?
Thanks for watching. I got it early to do some testing and feedback prior to launch for Ecoflow. I decided before I threw it in a closet I'd do a detailed review for people so they could determine if it was right for them or not. It will be out day after tomorrow (16th) and those discount codes I posted will be active for the first 300 people (in the US) if you're interested.
@@reviews2you cool this battery type seems the way to go
Instrad of throwing it in the closet i will take it off your hands 😀
@@Gkres0a Haha I hear you. It's going to be my new bug out power generator due to its light weight and high Wh capacity and inverter size (and solar input). So I'll keep it charged and ready to go. It's not perfect, but it's very hard to beat for its pricepoint as of today.
@@Jakepp235 Many will disagree and prefer the lighter weight of the NCM batteries, it's personal preference but for me (and I'd guess the majority of folks) I'll trade 2-3 lbs for safety and longevity. The counter argument is that you won't ever cycle it that much anyway, that something new will come out long before it hits its life cycle even with a NCM battery for most people, and I think that's largely a valid claim. However, I still prefer having safer battery chemistry and the fact it lasts much longer is just icing on the cake. The slight increase in weight doesn't affect me and they were able to keep this Delta 2 the same form factor size as the original so it didn't get larger because of it.
Hi Jason, you cannot turn off the D2 while it is charging from the AC wall-outlet, instead you first have to disconnect that charging cable. I don't understand the benefit behind this awkward setup. Did you find a reasoning for it?
It's because it's set up to be a UPS and it has to have power on to do that I think.
@@reviews2you Thanks Jason! From that point of view it makes sense. However, I think the D2 is mostly used as a normal power station and only to a very small extent as UPS. Especially because switching time isn't really great. In order not to make life unnecessarily difficult for the user, it should be possible to set the desired functionality via app
I can't disagree with you on that.
Did you measure how much power it draws from the wall when its batteries are charged and no load (or a light load like 100W) is connected ? I've read that for that kind of use (EPS mode) it is very wasteful... Is it true?
I just tested this out for you, it pulls about 9.4 watts to be on with the AC inverter on. Not super wasteful but I bet it's less efficient than a true UPS.
Spare battery has no other input nor output? You can't independently charge it without the main unit????? That is lame. That is really really disappointing.
Why can they do what Bluetti has been doing?
My guess is that they're trying to hit a price-point by not adding the DC regulator and circuit board needed for input/output of DC and they'd also need an internal AC charger to charge it separately. I can see on a product in this price range why they don't have the wall charging ability as that also creates the need for fans and venting and would probably take away from the storage bin, but the DC in/out would have been very nice to have I agree with you.
@@reviews2you It looks like the extra battery is only $100 cheaper than the main unit. At that price, it should have included a DC in and out.
@@fongsa1yuk Not sure what you're seeing but it's $999 for main unit and $799. Use links in description to see. That coupon code should still be good too.
Returning the Anker 757 as the solar xt60 cable has to be unplugged at night and replugged in the morning and press the display button to get it to accept solar on sunrise. 🤷. I've ordered the UK Delta 2 and the additional battery. I hope it lives up to your review
I hope it does too. I haven't tested that with the Delta 2 but you can program it to not shut off so in theory when sun start producing energy in the morning it should automatically start taking off once voltage comes up enough. Let me know how it works out for you.
Hello Jason, question for you or your community. I have the delta 2, with backup delta 2 battery (1800W Output/2700W Peak). I am testing out in a home refridge which, when running, is pulling ~173 watts. When not running, pulls zero watts. After five hours the units (both D2 and backup D2) beeped and turned off. No surge, just tuned off. Is it plausible that the absence of wattage draw when fridge is idle caused the unit to shut down? I re-read the manual and didn't see an obvious caution, but am guessing. Maybe I need to connect anything that draws some type of wattage to keep this from happening?
I may be able to help you but I don't have enough info, when you turned the Delta back on was the battery dead or not? If not then it maybe timed out, you can login to the app and change AC power to never turn off. If it was completely dead then you may have an issue with the BMS and battery balance, contact Ecoflow. I'm unclear on if you have two Delta 2's or a Delta 2 and Delta 2 spare battery, but w/ a Delta 2 and spare battery I'd expect you to get about 14 hours from the fridge factoring in AC inverter loss and idle consumption. Half that for just the Delta 2.
@@reviews2you Hello Jason, I think I figured it out. First, to answer your question. I have the Delta 2 and Delta 2 backup battery. They are connected together and both powered on and both at 100% when running the fridge test. As stated, 5.5 hours in, they beeped and powered off. When I turned them back on, the primary was 82% and backup 73%. I also had it set to AC power as recommended. As it turns out, the online owners manual states the default shut off is 2 hours, meaning if there’s no power draw, it turns off. I checked today, and the Ecoflow app states the default auto-turnoff is 30 minutes (for both DC and AC). I assumed when running the test there’s no way a fridge’s compressor would not kick in during a 2 hour window, and assumed incorrectly. As it turns out, it exceeded 30 minutes easy. With that in mind, I am re-running the test with the defaults set at 30minutes.
Thanks for replying so quickly!
Quick follow-up: I re-ran the test with the Delta 2 and backup battery (D2) with idle shut-off set for 2 hours (vs 30 minutes from the first time). It lasted well past 10 hours and only flipped back to utility power as I was heading to bed. Many hours left in reserve.
I ran other tests with tvs/modems/gateways, etc., and between all tests (including the above) noticed a ~ 20% reserve variance between the primary/slave batteries. I 'read' they charge and discharge at an equal rate, but I haven't seen this.
I just bought a delta 2 max to add an additional reserve battery for extended outages. Great system! Thanks again for your reply and input.
@@theociba3762 I'm glad it worked out! Spare battery and main unit should ideally stay within about ~10%. You can run them both to 0% then charge back to 100% and I bet they stay closer next time. If you haven't, feel free to subscribe for more content that's similar. thanks
I'll drive it down once more this weekend, thanks for the response. I subbed day one. @@reviews2you
Hello,
I now have 2 solar panels of 150W, 12V Poly (facing South) and use them straight into my Ecoflow Delta 2.
I notice that with that, and when Sun is out on the panels, I can charge the Delta 2 to full in well under 3h.
I do get shading on the panels during the afternoon and the power drops significantly to only 40Watt.
I bought 1 extra solar panel 150W, 12V Mono (facing South-West) and put all 3 in series.
Dilemma ;
As I only use a relative small percentage of my panels, because I only use it to charge the Delta 2 power station, I would like to benift more from it to have more off grid power and wonder what to do. What's best system wise and what's best budget wise.
Do I buy the special extra Delta 2 battery from Ecoflow OR do I go for a DIY setup ?
The Extra battery from Ecoflow is at 800,ooEuro and gives an extra 1024Wh but needs to be charged by the Delta 2 itself as it can not be charged or used by itself.
The other DIY way has different options but comes at about the same cost for a little more power.
As with the extra Delta 2 battery there is no need to buy anything else, no solar regulators, no 12V to 220V converter.
On the other hand, with the DIY setup I do need 2x MPPT regulator (take 2x 100,ooEuro) , a 12V 100Ah LiFepo battery (around 500,ooEuro) and a 3000W pure sine converter (around 350,ooEuro) plus wires, fuses etc. (Comes easily at 1000,ooEuro) (And then better put a 4th solar panel of 150W 12V MONO, to balance and have 2x2 panels.
I also looked at the GroWatt all in one but that asks for more panels (for minimum requirement start working voltage)
That would be a nice system but even more expensive due to extra panels plus I only can put 6 panels (3x2 in slightly different orientation) due to space.
I'll reply in detail tomorrow, running out the door now. But I did see this and will address it for you as best I can.
I solved the problem of having more solar then my Ecoflow can take by using an external battery(100 Ah LFP with heatmats as it is located outside my house) where my solar is dumped.
When I see the external is getting full I turn off the AC-in of the EcoFlow battery's I have and they get charged from the solar. That likely means some losses but will also give solar a battery to go when the EcoFlows are full.
The external battery is charged with Victron MPPT's that have a load port that can be programmed to shut off when voltage is low, thereby protecting the external battery from getting discharged to much.
Ecoflows are set to charge to 95% SOC which is respected both when AC charging as when DC charging........ In that case the electricity can stay in the external battery.
Great power station as long as there's an internet. If the internet goes down, it becomes a boat anchor. Not a good choice for preppers.
Hey Ronald, I don't follow you, please elaborate.
@@reviews2you It appears the only way the Delta 2 can be setup or adjusted is through the app which requires an internet connection. Am I mistaken?
@@ronaldstowell4368 Yes you are, I cover it in the video but you can direct connect w/ bluetooth, no internet connection needed. But if you want to operate it away from home you need the internet, in that case just have the D2 run the router/modem in UPS mode in case power goes out.
@@reviews2you Thanks Jason. That moves the D2 to the top of my list. My only wish is that the second battery could be charged independently. Not a deal breaker, but it would be a bonus. I like to leave my fridge in the truck overnight when traveling and being able to take the second battery inside to charge overnight without interrupting the power supply would be great!
What's your thoughts between the Ecoflow Delta2 and the 4Patriot 2000x?
I haven't reviewed it but just glancing at it I don't see a single area where it would be better. And for the chemistry they say "lithium-IRON". What is that? Did they mean Lithium Ion? Lithium iron phosphate? Probably the latter based on 2,500 cycles to 80%. Heavier, less capacity, slower charging, more expensive. Not sure I'm seeing any benefits other than the word Patriot is nice. :)
@@reviews2you THANK YOU for your quick response.
Have a blessed day.
@@HDRomanin You too!
I couldn’t find the info. During testing, did they charge 3000 cycles at max ac charge?
I don't know their testing parameters but I highly doubt it. Best practices are to not fast charge but the option is there if you need it. Once in awhile won't hurt it, but constantly charge at full speed will reduce the battery life and puts strain on the charger and other components.
Whats the charging time when charging both units together? Is it 80 minutes x2? Since charging delta 2 alone is 80 minutes
80 minutes x 2. The limiting factor is your household outlet, they typically are 15a.
@reviews2you thanks for reply!. Question for ya, I read a review that said there was an issue when using both the delta 2 and the extra battery. The issue was that the delta 2 power station would drain substantially faster than the delta 2 extra battery. He noted sometimes even upward of 15 percent. Like the delta 2 would die and the extra battery would have 15% left in it. What's ur experience?
@@Juan1985g Hey Juan, they can vary up to 10% per manufacture. With mine they stay pretty close, usually within 5% or so. That percentage isn't an exact amount. You may need to cell balance once in awhile.
I think max is 850Wh not 1KWh
Do you mean how much you can expect to get out of it after inverter loss? I do address that. Thanks for your view
How did you buy one when they were not available yet?
I was having issues with my River Pro w/ spare battery not being recognized and told them after 2 rounds of getting bad units I was going to have to return it. They apologized for the problems and asked if I wanted to try their new Delta 2 as they had a few ready for early purchase, they sent me an amazon link to pick it up ahead of time.
How many cooling fans does the Delta 2 have
Hey Allan, it has two fans. I've been running it for several months now, had no cooling issues. Thanks for watching.
Is it compatible with the DELTA Pro Smart Extra battery?
No.
Would it be possible to connect 2 Delta2 together as extra power ?
Hello, how do you mean more power? Push more than 1,800w from one unit? No. But you would have the full 1,800w with each. There is no benefit in connecting them. You could feed power from one to another, but you can do the same with a spare battery and that's cheaper. If I didn't understand your question correctly let me know and I'll try again.
Yes, more power, more Watt available to power a bigger load.
I would use the Delta 2 in my mini camper time to time (maybe 10, maximum 20 times a year) but mainly as an off grid power (all year round) in a cabin.
.
I now have 2 solar panels of 150W, 12V Poly (facing South) and use them straight into my Ecoflow Delta 2.
I notice that with that, and when Sun is out on the panels, I can charge the Delta 2 to full in well under 3h.
I do get shading on the panels during the afternoon and the power drops significantly to only 40Watt.
I bought 1 extra solar panel 150W, 12V Mono (facing South-West) and put all 3 in series.
Dilemma ;
As I only use a relative small percentage of my panels, because I only use it to charge the Delta 2 power station, I would like to benift more from it to have more off grid power and wonder what to do. What's best system wise and what's best budget wise.
Do I buy the special extra Delta 2 battery from Ecoflow OR do I go for a DIY setup ?
The Extra battery from Ecoflow is at 800,ooEuro and gives an extra 1024Wh but needs to be charged by the Delta 2 itself as it can not be charged or used by itself.
The other DIY way has different options but comes at about the same cost for a little more power.
As with the extra Delta 2 battery there is no need to buy anything else, no solar regulators, no 12V to 220V converter.
On the other hand, with the DIY setup I do need 2x MPPT regulator (take 2x 100,ooEuro) , a 12V 100Ah LiFepo battery (around 500,ooEuro) and a 3000W pure sine converter (around 350,ooEuro) plus wires, fuses etc. (Comes easily at 1000,ooEuro) (And then better put a 4th solar panel of 150W 12V MONO, to balance and have 2x2 panels.
I also looked at the GroWatt all in one but that asks for more panels (for minimum requirement start working voltage)
That would be a nice system but even more expensive due to extra panels plus I only can put 6 panels (3x2 in slightly different orientation) due to space.
The fan only works when it's charging?
No, the fan will come on if the load is high enough to cool when in use.
What about wireless phone charging?
No wireless phone charging.
Does the new delta 2 replace the delta 2000 max?!
No, it replaces the delta.
I would go for a second unit and skip the extra battery.
Yeah several have gone this way. There are pluses and minuses to each. Still a solid battery generator a year later!
Thanks, I just ordered a Delta max with a Delta 2 , instead of an extra battery.
An idea I had seems to be real, in the form of next year's Ecoflow 'Ultra'.
Batteries and the inverter/controls, are separate units all together!
May be the tech will trickle down to smaller units.
240v would be nice in a smaller 15 ish amp unit, too.
3/4 hsp / 8 amp deep well pumps, are everywhere here. Most have starter capicators and do not have a huge starter draw. I run every thing, but a 240 hot water heater, easily on a Honda 35000.
It's a; thrifty, trouble free, clean sine wave unit.
Pull start is getting old!
@@christophergallagher531 Yeah I wound up buying a Max 2 w/ a Max 2 spare battery and kept the Detla 2 which can use the Max 2 spare battery. This configuration gives me a lot of flexibility. The industry is moving very quickly, as these are much better than devices we could get just a handful of years ago. We may very well start seeing split phase 240v in more mobile units in the coming years. The Ultra is enticing, I haven't had a chance to check it out. I went a different direction w/ my home backup and will be covering that in a future video.
It is happening fast.
I gave up on the delta pro set up, looking at the advances coming.
I really have research panels, and get the ball rolling. Looking forward to your reviews.
Pity about appalling customer service from both overseas PR and EU website. PayPal dispute filed
What happened? I have had good luck with Ecoflow's customer service but they are overseas so they tend to respond in the middle of the night and you can't easily get anyone on the phone it's all email based.
@@reviews2you it's all over paying full price and no 5 % discount code which left a bad taste but the charge for a £70 case and not receiving the free one. The complete arrogance of saying one thing and failing to follow through with a refund and now the total blanking of emails which have been polite. If this is how they behave with customer service, It concerns me that any warranty support I may need on a package I paid nearly £2k for, will be non existent.
@@under2boots I'm sorry to hear that. You probably aren't interested in them at all anymore but I just posted a new deal under the comments, $100 off the main unit and another $100 off the spare battery if you want to return yours and order that one. The discount is immediate so you don't have to wait on a rebate or money back etc. Sorry for your experience, so far they've been good about getting back to me but can take up to 2 business days I've found.
The 3000 charge cycles is interessting , but the nose is so loud when charging the Delta 2. So I still hesitate to buy this model
It depends on what you're comparing it to. It's not louder than my Bluetti EB70S, it is louder than the new Ecoflow River 2 Max. They did just roll out a firmware upgrade to the River 2 since I did the review that vastly improved the features (automation etc) and it seems like it may of quieted it down or I just got used to it. It's really not that bad, but not noticeable. I'm not brand loyal, I have Ecoflow, Jackery, Bluetti, Rockpals etc and this Delta 2 is my favorite one as of the time of this comment for what it's worth.
@@reviews2you I have A Jackery 1000....and almost no sound when on the charge. But it does take serval hours to recharge.....very long....
@@013gaston I have a jackery 1000 too. External power brick that gets very hot, slow charge, NCM battery chemistry, no app etc. No comparison to the River 2 IMO.
@@reviews2you I do agree ...that is why i want to change for the ecoflow Delta 2 . The only thing i do not like is when it is charging it is very loud . Because i live in my van , most of the time i will go to a Tim Horton ( or other restaurents) to charge my battery.... So if i try to charge my Delta 2 , the noise may disturb other poeple near me...........But I do agree that the Delta 2 is way better than my Jackery ............Thanks and my regards
I understand. They just updated the app and in the AC customized charging section there is a selection for "Quiet Charging". I had't tried it yet since the software was just updated so gave it a quick try for you, had it charging for ~5 minutes and absolutely zero noise when in Quiet charging mode. Perhaps a fan will kick on in a bit if he heats up but as of now it's charging at 212w and zero fan noise. Hope that helps
Are dimensions L x W x H?
Yes 15.7 x 8.3 x 11.1in
Ecoflow have been appalling for me. I cancelled the transaction and there has been no communication from them for a refund. They have withheld the money for no reason. I live in the UK and every place I see this companies products reminds me how bad the customer service is. Great for content providers.....a disappointment for those of us that make the unfortunate decision to get involved with them.
I'm not a pawn for any company, but honestly out of all of them (except maybe Jackery) they have been the best. Send an email to support@ecoflow.com or login to their facebook group and post publicly on there, they jump on stuff quick. Sucks you had a bad experience and thanks for letting us know, follow back up later with how it came out.
They have been a good company for me too sicne I discovered them and anker too. I love my delta 2,river 2 and river pro I have from eccoflow and my anker powerhouse 555 and 757 too.
can i charge input with 220 V ac. ?
Hey Ken, no it can't. 120v only w/ AC.
