Thanks for the video. Have the same van and bought the same Aims switch and inverter. Have the builder circuit too. Different power station though. (Fosibot). Only question is how you are wiring the aims switch. I get the white wire in the middle but what are the red and the ground going to? Directly to battery terminals? Thanks
My Sprinter came with an extra battery under the passenger seat. Would it be best to connect the DC to DC charger to the extra passenger battery instead? Also using a Delta MAX with maximum charging capacity of 800Watts... Would a 60 Amp do the trick? or does it need to supersede the EcoFlow max charging capacity? Thanx, Robert!
I ran this setup for about 6 months. First, it is crucial to make sure the battery is disconnected and all the residual power has dissipated. If not, an error code will likely be triggered that will require a visit to the shop. It will be a costly fix. Second, my VS30 gave low battery warning messages when drawing 900W while driving. I eliminated this by adjusting the charge rate down even further. Third, my starter battery needed to be replaced after 18 months and 50k miles. I don't know if inverter charging was contributory, but I'm now researching alternatives.
that is because your alternator does not generate enough power to meet the demands of this power-hungry invertor and your cars built-in loads such as radio, ventilation, AC if any etc. so that your battery kicks in as being an additional source of power and you get what you observed.
@@ric8361 Yep. Even with the power draw dialed down, it was too much. I've now switched to a DC DC charger, which charges it at a much slower rate (~400W) but fast enough for my needs, and more importantly hasn't caused any problems so far (~2 months use).
Hi guys! Thank you for your information in this video. I too have a sprinter van and a Delta Pro as my camper house battery system. What I am interested in is how you connected this inverter to your actual starter battery. I didn’t see this information in the video but want to replicate it to help charge my Delta Pro. Any information you can provide would be greatly appreciated!! Thank you
Hi…thanks for the great info! Great set up with the inverter! I see that you have wiring from the 12V discharging panel off the DP…r u using the ANDERSON PORT? Do you have it connected to a fuse box? CAN YOU GIVE ME THE LINK FOR THAT CORD? THANKS!
Hi! Love this and want to do this in my skoolie to charge my DP. How did you connect the inverter to the battery, just an extra set of terminals? Did you put a breaker in between? how did you run the cabling? Also - in order to simplify the installation, could I skip the auto on/off and just manually turn on the inverter when i start the engine, and then turn it off when I turn it off?
Hi - Thanks for your comment. The inverter is just connected to the battery via 4ga battery cables under the drivers seat. I did not add a breaker - but probably advisable to do so. The cabling is only about 24" long and runs out the bottom of the drivers seat base and connects directly to the inverter. Yes, you definitely could just manually turn the inverter on/off. Let us know if you have any other questions that we might be able to help with. Have a great day.
Perfect video for me! Have a 2023 Sprinter with the builders kit and the upgraded 280 amp alternator. This really reassures me that I can run the 1000 watt inverter! I wanted to do this instead of the dc to dc because the solar will be using that charging port and I don’t want to switch back and forth. Thanks!
They are connected underneath the seat which leads to the battery and the switch is connected to the ignition terminal under the driver seat. It is in the video as well.
@@GayeNRobert Thank you for your reply. So they connect directly to the starter battery terminals? I really like your videos by the way and appreciate the information! It's been very helpful in my very slow pace piece by piece build. I have an ecoflow delta max and 2000W AIMS inverter connected to my aux AGM battery (underhood), but its a pain to turn the inverter on and off and easy to forget to turn off which is a quick drain on the battery. So the ignition toggle is going to be a great addition!
I have the Ecoflow Delta Pro in our sprinter van too. I only use the Pro for our 110 power needs and short term powering our air conditioner. Seperately I have a line running from my sprinter battery to another house battery with a manual shutoff to charge the house battery when we're driving only. And a 380 watt solar panel feeding the Pro. Our house battery only powers our 12v water pump and overhead lights. Can I run this line to a 5000w inverter and then to my Ecoflow to charge? Do I need to adjust the amps on the Pro? Side note: we also have a 30amp external port for campgrounds I've wired for the air conditioner. Your the first person I've seen dealing with these ecoflow Pro issues. James and Kim (We also have a channel named: Treasure Hunt Foodies)
Hi James - we will check out your channel - sounds interesting. As far as using the cable from the Sprinter battery to a 5000w inverter - the most that a 2022 Sprinter can pull from the alternator is 80amps - or 960w. So, you could use a 1000w inverter that is ignition on switched and then set your delta pro to only charge 1000w or 900w to be safely under the 80amps. The inverter solution works very well.
@@GayeNRobert Hi and thanks so much for the responce. I'm really excited to get this to work powering up the Ecoflow while driving. So I shouldn't use the 5k inverter? Get a smaller inverter?
I too have a Sprinter with a Delta 1300. What is the advantage of charging it this way vs using a DC to DC charger? Do you have any concerns about drawing too much amperage off the inverter (especially when idling the engine)?
Good Morning - I think the main advantage is the simplicity of the setup - not sure if you can buy a 80amp dc to dc charger (maybe) but we had 3 "30amp Victron DC to DC" on our 2019 Sprinter along with much more cabling. No concern with drawing too much amps - from our experience in our 2019 Sprinter - we did not see a difference in alternator output at idle compared to more rpms. DC to DC works fine, the inverter just simplifies the entire setup. Enjoy your weekend.
@@GayeNRobert I can buy a 60 amp dc-dc renogy charger. I see the 1000W inverter is around the same price, so yes youre getting 90A using it, but it makes a bunch of noise.. is it possible the dc-dc is quieter and just as simple to set up? I understand will be 30% slower charge rate... Just trying to figure electric out before starting to build my skoolie and I want to use ecoflow delta pro to power it...
I was just thinking about doing this setup for the ecoflow pro as it looks like the ecoflow car charger shares the same input as the solar, and swapping plugs every time I drive seems like a pain. Using an inverter to charge on the ac input looks like a great solution. My concern would be running the inverter all the time off the alternator, Will that shorten the life of the alternator? My mb sprinter has a factory 280amp alternator
Justin, have you figured out a way to connect an inverter to your vehicles starter battery to keep your Ecoflow Pro charged up while you're driving? I'm having a terrible time figuring this out. Have you had any luck? I'd welcome anything you care to share about how to do this.
@Sheri I have not actually hooked it up yet, but I plan on doing the setup similar to the video but using a smaller inverter to hopefully not stress the alternator.
@@justinlarhette1522 Thanks for replying. I don't know if you are hoping to use this set up specifically to recharge a Delta Pro portable power station, but if you are, I'll share this information with you in case it is helpful. I've been on the phone daily for a week- no exaggeration- talking to manufacturers of the Delta Pro portable power station and various inverters and mechanics and upfitters, and have been told this set up won't work because the standard alternator in most vehicle's won't furnish sufficient power to the inverter to recharge the Delta Pro. According to Ecoflow, who manufactures the Delta Pro, it requires 1800 continuous watts to recharge, and if the wattage dips below 1800 it will not recharge and may even just shut down. When I told Ecoflow that I knew of some people who were using a smaller inverter in this kind of a set up (recharging off of their vehicle's starter battery) they said "Well it MIGHT work, but there's no guarantee." A mechanic who works in upfitting these devices for camper conversions told me it definitely will NOT work unless I replace my alternator with a much larger alternator; the standard alternator in my Promaster 2500 is 180 Amps and will not generate enough extra power to provide the inverter with the 1800 watts needed to recharge the portable power station. They also said that I would have to replace the starter battery in my vehicle because to handle this kind of power it MUST be a minimum of 400 Amp Hours and the standard starter battery in a Promaster is only 95 Amp Hours. Furthermore, the more powerful the starter battery is- the bigger it is in physical size and therefore it will not fit into the compartment where a Promaster's batttery is housed (under the driver's feet, in the floor of the cab). I'm so frustrated because I've seen several of these videos where people are hooking up inverters to recharge a portable power station; and they're defying everything I've been told-- but they do not follow up and tell us if it actually worked or not- or if perhaps it worked, but only intermittently. While the Delta Pro portable power station recharges rapidly on an AC wall outlet, and at Electric Vehicle charging stations, it would be so much easier to be able to recharge it off of the vehicle's starter battery and an inverter, while driving the vehicle. I discovered while on a long trip through the Midwest this past holiday season, that there are still places where it's hard to find an Electric Vehicle charging station, and it left me stuck without appliances when my portable power station needed recharging. I was also severely cautioned that with this kind of power, if a flooded starter battery is used in the vehicle, with this kind of a set up it could result in the battery boiling over- so to be safe, stay away from that type of battery. I sure would like to know if there actually is a way around what I'm being told by everyone I've spoken to who is telling me that this kind of set up just isn't possible with this particular portable power station, without making costly changes to the vehicle's alernator and the starter battery. I don't mean to question or criticize the people who have taken time to post these videos showing their setup, but, In the absence of follow up videos confirming that this setup actually did work reliably over time, I'm really questioning what I'm seeing in these videos. Can ALL of these people I've spoken to from numerous different manufacturers be wrong? If you care to share what you learn as you get further into this, I would certainly welcome that information if you care to send a comment my way. Good luck with your effort to figure out what works for you!
Pretty cool but holy crap are you losing a bunch of power to converting Sprinter's DC to AC and that AC in the EcoFlow into DC for battery storage. Wouldn't it be easier to skip the middle man and use a DC to DC converter to optimize the voltage level you get from the Sprinter (DC to DC Boost/Step Up Converter 12V to 48V probably wanna oversize your converter and get something twice the wattage limit of the Solar Input). I think the downside is EcoFlow Solar Input is never as powerful as AC input...but if you lose 20% on one leg of the conversion and then lose 20% of that on the next leg of the conversion....if you start with drawing 900 watts from the Sprinter you're down to 576 watts the EcoFlow battery is actually getting...but that might be irrelevant for you because the Sprinter is being driven so you're going to be juicing up the Sprinter battery anyways...
Eric Klein I'm searching for someone who can tell me how I determine if my Promaster 2500 can handle a Pure Sine Wave Inverter that is 1800 watt / 120 volt / 15 amp. That is the smallest inverter that Ecoflow said will allow me to recharge my Delta Pro while driving. I'm a widow and a senior now and need to move into my van full time for more affordable living. Keeping my Delta Pro charged is a huge obstacle that I must get resolved quickly as the my move out date on my rental home is approaching. While I was able to do the van build myself, I know nothing about vehicles and batteries and inverters. Ecoflow also said that for significantly faster recharging I could also use an inverter that is 3000 watts 240 volts 12.5 amps and I'd prefer the faster recharging time, but after reading the comments here, I'm guessing that's too big for my Promaster to handle. I'd be very grateful for anything you can share. Thank you!
@@sheri4673 that is the smallest inverter you can use with your Delta Pro? Does the Delta Pro allow you to adjust the charge rate? I think that might be a feature only Bluetti has. If you can’t adjust your charge rate then EcoFlow is correct. A smaller inverter would constantly trip as the delta pro tries to pull 1800W continuously. I’m fairly certain your Dodge Ram Promaster has a large enough alternator to allow you to pull 1800W. You would probably want to step it up to a 2000W model or slightly higher just so you are not running the inverter at 100% all the time. An inverter running at full load WILL eventually fail within a year or two but an inverter running at 80% load stands a good chance of lasting you a few years minimum, that’s just the reality with inverter circuits and how hot they get. Heat will be another consideration. You do not want your inverter tucked up the passenger seat with very little airflow. Wherever you have it placed, put it somewhere where both ends of the inverter (likely fans insides the inverter on both ends) will have at least a few inches of unobstructed air flow. I even saw a guy with a homemade EV Passat rig up some fans in his trunk that sucked the hot air exhaust out through the top of the license plate when the trunk hit a certain temp. Seriously consider mounting your inverter on the top of the interior of your van with the exhaust side close to a roof fan. This could save you a lot of energy when it comes to cooling your van in the summer. When you drive around the inverter will pump out enough hot air to fight the vans on board AC so by the time you get to your destination you might have a van that is still toasty in the back. You need to find a mechanic you can trust, preferably one that at least has some experience with either audio mods or vanlife mods. The audio guys run giant amps that require a lot of power so they are very familiar with installing aftermarket alternators that can put out 300-400amps. Your 2000W inverter is going to require 140-160 amps which will be pushing the limits of a stock alternator most likely. After doing some reading I’m seeing 220amps pop up a lot when I search for 2500 Promasters but not knowing the year of your Promaster I cannot give you a definite answer. An inverter using 140+ amps is likely too much. You would probably want to look at getting a high output alternator installed and maybe even a second battery. I’m not sure if the second battery will be of much help as you’re going to be relying on the Delta Pro for your actual day to day power but I’m not sure if having a single starting battery when using your alternator as heavily as you will be is a safe system. If a second starting battery can provide redundancy so that there is no situation in which the inverter draw kills one starting battery and you’re stranded, then a second starting battery would save you some serious headache. My understanding is the starting battery is used as a float between the alternator and the inverter, not sure if it’s common to connect directly to an alternator. I’ll have to do more research. For the time being I would plan on at least a 2000W pure sine wave inverter and a high output alternator (350 amps) to be on your list.
@@sheri4673 another option would be to find someone with two EcoFlow units that charge slower but combined have the same capacity as your Delta Pro. You could trade them and then use the smaller units one at a time on a smaller inverter in your van. Check to see if the Delta 2’s can be charged at 800W. If so you would lose out on the giant inverter as one unit in your delta pro by trading but this would save you money on your van as you likely wouldn’t need a bigger alternator or a $300 inverter. You could probably use a $150 inverter with the stock alternator.
Hi Vladimir - hope all is well. Here is the inverter and the ignition switch that I used. The main reason that I went with this inverter was because they also sold an automatic ignition switch for their product. Might be others out there. I totally love this solution - so easy, perfect for the Ecoflow Delta Pro as it allows me to change the AC charge watts to whatever I need and in this case 1000 watts. So, the combination is really awesome. Let me know if you have further questions.

Hi Vladimir - sorry for the delay. With the Sprinter, there is only 80amps allowed to be used from the stock alternator - so that is just under 1000 watts. A 2000 watt inverter could cause issues with the alternator. Hope this helps.
This is great and I'm planning to do this on my 1998 sprinter van, I'm just worried about my alternator being that it's only 90amps alternator and it's also powering the ac compressor, adding another 1500watt inverter might be pushing it. But might try it, charging my delta pro at that speed is a luxury for any campervan owners. thanks for the tips!
Aldino so far everything has worked for us. Love the flexibility of new power stations. Thank you so much for watching and taking the time to comment. Let us know how it worked for you!
Hi Aldino - Yeah, 90amps might not give you much extra to work with. We have a 220amp alternator in our 2022 - and Mercedes states that 80amps is available - which is 960watts. Have a great evening!
@@GayeNRobert Thanks for replying, I just found out that adding an auxiliary battery to the vehicle to power the inverter would actually work. what dyou think?
@@GayeNRobert Can you tell me how I can determine if my vehicle can handle either a 1800 watt or 3000 watt inverter? I purchased a Delta Pro and want to recharge it while driving. I know nothing about vehicles or their alternators and batteries. Somehow, I was led to believe that hooking up an inverter was as simple as connecting two ends of a cable - one end to the battery in the floor of my Promaster, and the other end to the inverter, but in this video it looks way more complicated. Can you tell me anything that will help me understand just how complicated this is? Ecflow said I need a Pure Sine Wave inverter in one of two sizes: 1800 watts 120 volts 15 amps OR for faster recharging 3000 watts 240 amps 12.5 volts. I would be so grateful for anything you can share to point me to what I need to learn to determine if this is a good way to keep my Delta Pro charged. I'm a widow about to give up my rented home to live more affordably in my van and start a new life on my own seeing the country. Keeping my Delta Pro charged is the last obstacle, and my move out date is approaching in less than two months, I've got to resolve this quickly. I did the entire van build on my own and would like to be able to install the inverter myself, but what you show in this video is way over my head. In this video, other than installing an on/off switch are you doing something custom or is it always this complicated? Do you know if any inverters come with an on/off switch? Thank you again for anything you can share.
Gaye N Robert Can you please, PLEASE assist me? I have spent countless hours calling Ecoflow and numerous Inverter manufacturers trying to figure out how to recharge my Delta Pro using an inverter connected to my vehicle's starter battery, while driving. After rewatching your video numerous times, I am left totally confused- clearly I am not understanding what you've done with this set up. I've basically been told that I cannot recharge my Delta Pro using an inverter while driving because my vehicle's alternator and starter battery are too small for the demands of the size of the inverter that Ecoflow told me is required to recharge the Delta-Pro. Clearly, you have this working, but what you show in your setup, is contrary to everything I've been told by Ecoflow. First, I was told the Delta Pro must be connected to an inverter that provides 1800 watts of continuous power or it will NOT recharge, and in fact, the inverter might shut down entirely if the power drops below 1800W; therefore my inverter MUST be at least 1800 Watts- yet you're recharging using a 1000 watt inverter. How? Ecoflow also told me that it is not possible to lower the recharging rate, yet you are recharging at 900 Watts- how are you controlling the wattage input to recharge at 900W as you stated in this video? Also, you are using Pass-Through charging and running your refrigerator while simultaneously recharging the Delta Pro; Ecoflow told me there is no option to use the Delta Pro to power any appliances while it is receiving an AC charge, how are you doing this? Is your Delta Pro plugged into an AC outlet on your inverter or have you hard-wired these two components together somehow? What am I missing? Can you please explain? With everything I have been told, it simply will not be possible for me to use an inverter to recharge my Delta Pro using the energy generated by my running vehicle because the alternator in my vehicle is 180 amps and therefore too small to supply the 1800 continuous watts needed to recharge the Delta Pro- yet you've done exactly that, so I really need to understand how you've done this. Can you please help?
Hi, you can definitely change the maximum charge voltage to any watts in 100w increments. We have a Sprinter with an alternator that can handle pulling 80amps while driving - your alternator would need to be the same. Our refrigerator is being run by a Ecoflow River Pro and the Delta Pro charges the River Pro via 12v. It all works - you need to find out how many amps that your vehicle allows to be used for charging the ecoflow, then size the invertor correctly and reduce the charging watts on the Delta Pro. Our Sprinter can handle 80amps - so we have a 1000w invertor (80 x 12 = 960w) and the Delta Pro is set to max charge of 900w. it'll work, you just need the correct settings and equipment for your vehicle
@@GayeNRobert Thank you so very much for the reply, it is very helpful, but what I'm not clear on is how are you keeping your Delta Pro recharged? If you care to read further, I explain what I've been told by Ecoflow's tech support and numerous tech staff from various inverter and battery manufacturers - all telling me that I cannot harness the power of my running engine to keep the Delta Pro charged while I'm driving, and that's exactly what I'm trying to do. I want to recharge my Delta Pro off of the AC outlet on an inverter that is connected to my vehicle's starter battery while I'm driving, so that I no longer have to search for shore power or an EV charging station (I have not set up a solar panel system yet). Ecoflow told me that to recharge the Delta Pro from an AC outlet on an inverter, the inverter MUST supply 1800 continuous watts to the Delta Pro or it may not recharge at all and may just shut itself down entirely. On top of that, I'm told by several mechanics that for the inverter to supply that kind of power to the Delta Pro, my vehicle's alternator must be MUCH bigger than what it is currently,- the standard alternator in my Promaster is 180 amps, I'm being told I need almost twice that. AND in addition to getting a new, larger alternator, my starter battery which came standard in my Promaster is 95 amp hours and for the inverter to furnish the Delta Pro those 1800 watts, the starter battery MUST be at the very least 400 amp hours and if I upgrade my starter battery to one with 400 amp hours, it will be a specialty battery and would likely be physically larger in size and would not fit into the same location where my existing starter battery is housed, which is under the driver's feet in the floor- there's just no room to spare in that little cubby hole. Ecoflow also told me that the only option for changing the watts at which the Delta Pro recharges is through the cell phone app and that feature is available ONLY when recharging the Delta Pro at 12 volts- NOT when recharging via AC current. And while the Delta Pro CAN be recharged at 12 volts while driving by using the vehicle's cigarette lighter port, a full recharge at 12 volts takes 35 hours, so even if I'm just topping off the charge in my Delta Pro, there's no way for me to keep it recharged at that rate because each night when I stop driving for the day and need to use my lights, my computer, or my cooktop, I'd be draining the Delta Pro down and running out of power again- I can only drive about 6 or 7 hours each day, so, 12 volt recharging just can't keep up. At every turn, I'm being told there's no way to recharge my Delta Pro while I'm driving, without making costly modifications to my vehicle. But unless I'm completely misunderstanding your video, that's exactly what you have accomplished. So, can you please tell me, how were you keeping your Delta Pro charged up within this inverter system you show in this video? I cannot always tell if, and when, I'm being advised correctly, but I do know that I've received much conflicting information through the countless phone calls I've made so far. Again, I'm very grateful for the information you share. This has been beyond frustrating - and to make matters worse, I'm getting on the road in just a couple of weeks as I move out of my home at the end of this month and take to van life full time - a new life after losing my husband. I'm so hoping to have this issue resolved by then so that my transition to this new way of living might be a bit easier- staying powered up means everything to living on the road, so I've got to decide on a solution. Again, many thanks to you for anything you have time to share!
I finally got around to trying this, and unfortunately it did not work. The wattage the inverter is putting out must exceed the wattage the EcoFlow is demanding. If not, once that threshold is reached, it will stop charging. So it will work on EcoFlow models that allow the user to set the input wattage but not on models that don't. My older Delta charges at 1000+ watts, so I would need a 1500W inverter, which is well beyond the limits of my Sprinter's alternator.
D. Lowe that's a bummer it did not work for you. I think the important thing is you were not afraid to give it a go and try to figure it out. Thank you for watching!
@@sheri4673 I owned an older Delta at the time I wrote my earlier comment. I've since upgraded to a Delta Pro. I believe all the newer EcoFlow models allow the user to set the wattage it draws. VS30 Sprinters display a warning message if the charging system is over taxed. From trial and error, I've learned to adjust my EcoFlow according to how hard the engine is working. I never set it above 800W. I have a Renogy 1000 inverter. Unless you have a dual alternator, it is probably unwise to pull 1800W (or 150 amps). So you don't need a large inverter. FYI, the Delta Pro can charge simultaneously from the inverter and the cigarette lighter port. I keep it constantly plugged into this port so that it's trickle charging at 70-90W anytime the engine is running. I plug it into the inverter only as needed.
@@igoslomo If you've not seen it yet, take a look at D Lowe's reply to me, he shared some interesting information that was new to me. I'll gladly share with you what I learn. I've posted on a few different videos, I've got to get this figured out as I'm preparing to move into my van full time in a few weeks so I'll be watching the comments closely. I welcome you to do the same if you learn anything.
@@sheri4673 in the link I posted to an installation video there are some great comments... Then she has a follow up video which answers a lot of questions in the comments that were raised.
Hey Robert, where did you connect your 12v power lines for your inverter? Did you make new wires and run them directly to the battery? Is your solution still working well? Ecoflow is now selling an Alternator Charger, but they want $600! Looking for a more reasonable solution.
Amaaaazing lol... thank you... so I guess the red cable goes into the 110v input of the Ecodelta right? also let me ask you... as long as the engine is on, the alternator can provide 1000w? wow... if the engine is off, it will kill the battery quick I guess...
Hi - thanks for your comment. No, the AC cord from the Delta Pro plugs into the inverter. According to Mercedes, the 2022 Sprinter van provide 80amps which is 960watts. We only use the inverter with the engine running.
If you're still thinking about getting a Delta Pro, in case this is helpful to you, I discovered with mine that one wants to keep in mind that there are jacks on three sides of the Delta Pro that you need access to, and since it literally weighs 100 pounds, moving it about isn't easy. It needs to be strategically placed so you have room to get all the different power cables in and out as needed. I didn't think of this until after I designated a spot for mine, now I have a bit of a hassle when plugging in various cables due to limited space around the Delta Pro.
Thanks for the video. Have the same van and bought the same Aims switch and inverter. Have the builder circuit too. Different power station though. (Fosibot). Only question is how you are wiring the aims switch. I get the white wire in the middle but what are the red and the ground going to? Directly to battery terminals? Thanks
My Sprinter came with an extra battery under the passenger seat.
Would it be best to connect the DC to DC charger to the extra passenger battery instead?
Also using a Delta MAX with maximum charging capacity of 800Watts...
Would a 60 Amp do the trick? or does it need to supersede the EcoFlow max charging capacity?
Thanx, Robert!
This was a really useful video. Thank you.

Hi!
Love this and want to do this in my skoolie to charge my DP. How did you connect the inverter to the battery, just an extra set of terminals? Did you put a breaker in between? how did you run the cabling?
Also - in order to simplify the installation, could I skip the auto on/off and just manually turn on the inverter when i start the engine, and then turn it off when I turn it off?
Hi - Thanks for your comment. The inverter is just connected to the battery via 4ga battery cables under the drivers seat. I did not add a breaker - but probably advisable to do so. The cabling is only about 24" long and runs out the bottom of the drivers seat base and connects directly to the inverter. Yes, you definitely could just manually turn the inverter on/off. Let us know if you have any other questions that we might be able to help with. Have a great day.
Perfect video for me! Have a 2023 Sprinter with the builders kit and the upgraded 280 amp alternator. This really reassures me that I can run the 1000 watt inverter! I wanted to do this instead of the dc to dc because the solar will be using that charging port and I don’t want to switch back and forth. Thanks!
Thanks for sharing. That Delta Pro seems to be at home in your Sprinter.
Thanks for watching! Yes, love the Delta Pro. So easy compared to a full electronics install.
This is the solar generator that I need. Big, powerful and very fast to charge.
Yes, super fast charging. Really a game changer for the van!
For the remote switch, what did you connect the positive and negative cables to?
They are connected underneath the seat which leads to the battery and the switch is connected to the ignition terminal under the driver seat. It is in the video as well.
@@GayeNRobert Thank you for your reply. So they connect directly to the starter battery terminals? I really like your videos by the way and appreciate the information! It's been very helpful in my very slow pace piece by piece build. I have an ecoflow delta max and 2000W AIMS inverter connected to my aux AGM battery (underhood), but its a pain to turn the inverter on and off and easy to forget to turn off which is a quick drain on the battery. So the ignition toggle is going to be a great addition!
I have the Ecoflow Delta Pro in our sprinter van too. I only use the Pro for our 110 power needs and short term powering our air conditioner. Seperately I have a line running from my sprinter battery to another house battery with a manual shutoff to charge the house battery when we're driving only. And a 380 watt solar panel feeding the Pro. Our house battery only powers our 12v water pump and overhead lights. Can I run this line to a 5000w inverter and then to my Ecoflow to charge? Do I need to adjust the amps on the Pro? Side note: we also have a 30amp external port for campgrounds I've wired for the air conditioner. Your the first person I've seen dealing with these ecoflow Pro issues. James and Kim
(We also have a channel named: Treasure Hunt Foodies)
Hi James - we will check out your channel - sounds interesting. As far as using the cable from the Sprinter battery to a 5000w inverter - the most that a 2022 Sprinter can pull from the alternator is 80amps - or 960w. So, you could use a 1000w inverter that is ignition on switched and then set your delta pro to only charge 1000w or 900w to be safely under the 80amps. The inverter solution works very well.
@@GayeNRobert Hi and thanks so much for the responce. I'm really excited to get this to work powering up the Ecoflow while driving. So I shouldn't use the 5k inverter? Get a smaller inverter?
@@GayeNRobert I saw that I can set the Ecoflow but will need to read up.
Exactly what I needed to see, thanks for the video. "Orton method"!
I too have a Sprinter with a Delta 1300. What is the advantage of charging it this way vs using a DC to DC charger? Do you have any concerns about drawing too much amperage off the inverter (especially when idling the engine)?
Good Morning - I think the main advantage is the simplicity of the setup - not sure if you can buy a 80amp dc to dc charger (maybe) but we had 3 "30amp Victron DC to DC" on our 2019 Sprinter along with much more cabling. No concern with drawing too much amps - from our experience in our 2019 Sprinter - we did not see a difference in alternator output at idle compared to more rpms. DC to DC works fine, the inverter just simplifies the entire setup. Enjoy your weekend.
@@GayeNRobert this is a slick set up. Would love to pick your brain to replicate this with my four wheel camper build
@@GayeNRobert I can buy a 60 amp dc-dc renogy charger. I see the 1000W inverter is around the same price, so yes youre getting 90A using it, but it makes a bunch of noise.. is it possible the dc-dc is quieter and just as simple to set up? I understand will be 30% slower charge rate... Just trying to figure electric out before starting to build my skoolie and I want to use ecoflow delta pro to power it...
I was just thinking about doing this setup for the ecoflow pro as it looks like the ecoflow car charger shares the same input as the solar, and swapping plugs every time I drive seems like a pain. Using an inverter to charge on the ac input looks like a great solution. My concern would be running the inverter all the time off the alternator, Will that shorten the life of the alternator? My mb sprinter has a factory 280amp alternator
Justin unfortunately not sure if it will shorten the life expectancy, from what we've read no. Thank you for watching!
Justin, have you figured out a way to connect an inverter to your vehicles starter battery to keep your Ecoflow Pro charged up while you're driving? I'm having a terrible time figuring this out. Have you had any luck? I'd welcome anything you care to share about how to do this.
@Sheri I have not actually hooked it up yet, but I plan on doing the setup similar to the video but using a smaller inverter to hopefully not stress the alternator.
@@justinlarhette1522 Thanks for replying. I don't know if you are hoping to use this set up specifically to recharge a Delta Pro portable power station, but if you are, I'll share this information with you in case it is helpful.
I've been on the phone daily for a week- no exaggeration- talking to manufacturers of the Delta Pro portable power station and various inverters and mechanics and upfitters, and have been told this set up won't work because the standard alternator in most vehicle's won't furnish sufficient power to the inverter to recharge the Delta Pro.
According to Ecoflow, who manufactures the Delta Pro, it requires 1800 continuous watts to recharge, and if the wattage dips below 1800 it will not recharge and may even just shut down. When I told Ecoflow that I knew of some people who were using a smaller inverter in this kind of a set up (recharging off of their vehicle's starter battery) they said "Well it MIGHT work, but there's no guarantee."
A mechanic who works in upfitting these devices for camper conversions told me it definitely will NOT work unless I replace my alternator with a much larger alternator; the standard alternator in my Promaster 2500 is 180 Amps and will not generate enough extra power to provide the inverter with the 1800 watts needed to recharge the portable power station.
They also said that I would have to replace the starter battery in my vehicle because to handle this kind of power it MUST be a minimum of 400 Amp Hours and the standard starter battery in a Promaster is only 95 Amp Hours. Furthermore, the more powerful the starter battery is- the bigger it is in physical size and therefore it will not fit into the compartment where a Promaster's batttery is housed (under the driver's feet, in the floor of the cab).
I'm so frustrated because I've seen several of these videos where people are hooking up inverters to recharge a portable power station; and they're defying everything I've been told-- but they do not follow up and tell us if it actually worked or not- or if perhaps it worked, but only intermittently.
While the Delta Pro portable power station recharges rapidly on an AC wall outlet, and at Electric Vehicle charging stations, it would be so much easier to be able to recharge it off of the vehicle's starter battery and an inverter, while driving the vehicle. I discovered while on a long trip through the Midwest this past holiday season, that there are still places where it's hard to find an Electric Vehicle charging station, and it left me stuck without appliances when my portable power station needed recharging.
I was also severely cautioned that with this kind of power, if a flooded starter battery is used in the vehicle, with this kind of a set up it could result in the battery boiling over- so to be safe, stay away from that type of battery.
I sure would like to know if there actually is a way around what I'm being told by everyone I've spoken to who is telling me that this kind of set up just isn't possible with this particular portable power station, without making costly changes to the vehicle's alernator and the starter battery.
I don't mean to question or criticize the people who have taken time to post these videos showing their setup, but, In the absence of follow up videos confirming that this setup actually did work reliably over time, I'm really questioning what I'm seeing in these videos. Can ALL of these people I've spoken to from numerous different manufacturers be wrong?
If you care to share what you learn as you get further into this, I would certainly welcome that information if you care to send a comment my way. Good luck with your effort to figure out what works for you!
Pretty cool but holy crap are you losing a bunch of power to converting Sprinter's DC to AC and that AC in the EcoFlow into DC for battery storage. Wouldn't it be easier to skip the middle man and use a DC to DC converter to optimize the voltage level you get from the Sprinter (DC to DC Boost/Step Up Converter 12V to 48V probably wanna oversize your converter and get something twice the wattage limit of the Solar Input).
I think the downside is EcoFlow Solar Input is never as powerful as AC input...but if you lose 20% on one leg of the conversion and then lose 20% of that on the next leg of the conversion....if you start with drawing 900 watts from the Sprinter you're down to 576 watts the EcoFlow battery is actually getting...but that might be irrelevant for you because the Sprinter is being driven so you're going to be juicing up the Sprinter battery anyways...
Hey Eric thank you for you input and for watching!
Eric Klein I'm searching for someone who can tell me how I determine if my Promaster 2500 can handle a Pure Sine Wave Inverter that is 1800 watt / 120 volt / 15 amp. That is the smallest inverter that Ecoflow said will allow me to recharge my Delta Pro while driving.
I'm a widow and a senior now and need to move into my van full time for more affordable living. Keeping my Delta Pro charged is a huge obstacle that I must get resolved quickly as the my move out date on my rental home is approaching. While I was able to do the van build myself, I know nothing about vehicles and batteries and inverters.
Ecoflow also said that for significantly faster recharging I could also use an inverter that is 3000 watts 240 volts 12.5 amps and I'd prefer the faster recharging time, but after reading the comments here, I'm guessing that's too big for my Promaster to handle. I'd be very grateful for anything you can share. Thank you!
@@sheri4673 that is the smallest inverter you can use with your Delta Pro? Does the Delta Pro allow you to adjust the charge rate? I think that might be a feature only Bluetti has.
If you can’t adjust your charge rate then EcoFlow is correct. A smaller inverter would constantly trip as the delta pro tries to pull 1800W continuously. I’m fairly certain your Dodge Ram Promaster has a large enough alternator to allow you to pull 1800W. You would probably want to step it up to a 2000W model or slightly higher just so you are not running the inverter at 100% all the time. An inverter running at full load WILL eventually fail within a year or two but an inverter running at 80% load stands a good chance of lasting you a few years minimum, that’s just the reality with inverter circuits and how hot they get. Heat will be another consideration. You do not want your inverter tucked up the passenger seat with very little airflow. Wherever you have it placed, put it somewhere where both ends of the inverter (likely fans insides the inverter on both ends) will have at least a few inches of unobstructed air flow. I even saw a guy with a homemade EV Passat rig up some fans in his trunk that sucked the hot air exhaust out through the top of the license plate when the trunk hit a certain temp. Seriously consider mounting your inverter on the top of the interior of your van with the exhaust side close to a roof fan. This could save you a lot of energy when it comes to cooling your van in the summer. When you drive around the inverter will pump out enough hot air to fight the vans on board AC so by the time you get to your destination you might have a van that is still toasty in the back.
You need to find a mechanic you can trust, preferably one that at least has some experience with either audio mods or vanlife mods. The audio guys run giant amps that require a lot of power so they are very familiar with installing aftermarket alternators that can put out 300-400amps. Your 2000W inverter is going to require 140-160 amps which will be pushing the limits of a stock alternator most likely.
After doing some reading I’m seeing 220amps pop up a lot when I search for 2500 Promasters but not knowing the year of your Promaster I cannot give you a definite answer. An inverter using 140+ amps is likely too much. You would probably want to look at getting a high output alternator installed and maybe even a second battery. I’m not sure if the second battery will be of much help as you’re going to be relying on the Delta Pro for your actual day to day power but I’m not sure if having a single starting battery when using your alternator as heavily as you will be is a safe system. If a second starting battery can provide redundancy so that there is no situation in which the inverter draw kills one starting battery and you’re stranded, then a second starting battery would save you some serious headache.
My understanding is the starting battery is used as a float between the alternator and the inverter, not sure if it’s common to connect directly to an alternator. I’ll have to do more research.
For the time being I would plan on at least a 2000W pure sine wave inverter and a high output alternator (350 amps) to be on your list.
@@sheri4673 another option would be to find someone with two EcoFlow units that charge slower but combined have the same capacity as your Delta Pro. You could trade them and then use the smaller units one at a time on a smaller inverter in your van. Check to see if the Delta 2’s can be charged at 800W. If so you would lose out on the giant inverter as one unit in your delta pro by trading but this would save you money on your van as you likely wouldn’t need a bigger alternator or a $300 inverter. You could probably use a $150 inverter with the stock alternator.
@@ericklein5097 What a clever idea!!! I would never have thought of that!
Bob, can you please include the parts list links. Thanks so much!
Hi Vladimir - hope all is well. Here is the inverter and the ignition switch that I used. The main reason that I went with this inverter was because they also sold an automatic ignition switch for their product. Might be others out there. I totally love this solution - so easy, perfect for the Ecoflow Delta Pro as it allows me to change the AC charge watts to whatever I need and in this case 1000 watts. So, the combination is really awesome. Let me know if you have further questions.

@@GayeNRobert Bob, thanks so much for the reply. Was there a reason you bought a 1000 W instead of a 2000?
Hi Vladimir - sorry for the delay. With the Sprinter, there is only 80amps allowed to be used from the stock alternator - so that is just under 1000 watts. A 2000 watt inverter could cause issues with the alternator. Hope this helps.
Hi wouldn’t you have to change the wiring in the van to handle 1000w ? The wiring probably get to hot and melt ?
This is great and I'm planning to do this on my 1998 sprinter van, I'm just worried about my alternator being that it's only 90amps alternator and it's also powering the ac compressor, adding another 1500watt inverter might be pushing it. But might try it, charging my delta pro at that speed is a luxury for any campervan owners. thanks for the tips!
Aldino so far everything has worked for us. Love the flexibility of new power stations. Thank you so much for watching and taking the time to comment. Let us know how it worked for you!
Hi Aldino - Yeah, 90amps might not give you much extra to work with. We have a 220amp alternator in our 2022 - and Mercedes states that 80amps is available - which is 960watts. Have a great evening!
@@GayeNRobert Thanks for replying, I just found out that adding an auxiliary battery to the vehicle to power the inverter would actually work. what dyou think?
@@GayeNRobert Can you tell me how I can determine if my vehicle can handle either a 1800 watt or 3000 watt inverter? I purchased a Delta Pro and want to recharge it while driving. I know nothing about vehicles or their alternators and batteries.
Somehow, I was led to believe that hooking up an inverter was as simple as connecting two ends of a cable - one end to the battery in the floor of my Promaster, and the other end to the inverter, but in this video it looks way more complicated. Can you tell me anything that will help me understand just how complicated this is?
Ecflow said I need a Pure Sine Wave inverter in one of two sizes: 1800 watts 120 volts 15 amps OR for faster recharging 3000 watts 240 amps 12.5 volts. I would be so grateful for anything you can share to point me to what I need to learn to determine if this is a good way to keep my Delta Pro charged.
I'm a widow about to give up my rented home to live more affordably in my van and start a new life on my own seeing the country. Keeping my Delta Pro charged is the last obstacle, and my move out date is approaching in less than two months, I've got to resolve this quickly. I did the entire van build on my own and would like to be able to install the inverter myself, but what you show in this video is way over my head. In this video, other than installing an on/off switch are you doing something custom or is it always this complicated? Do you know if any inverters come with an on/off switch? Thank you again for anything you can share.
@@sheri4673What set-up did you use to charge it?
This is exactly what I’m doing. Same setup. How long do you feel comfortable idling the sprinter engine to charge if you’re not driving?
20-30 minutes at a time... you do have to be aware of it messing with the diesel particle filter
@@GayeNRobert that’s what I was thinking, and glazing
Gaye N Robert Can you please, PLEASE assist me? I have spent countless hours calling Ecoflow and numerous Inverter manufacturers trying to figure out how to recharge my Delta Pro using an inverter connected to my vehicle's starter battery, while driving. After rewatching your video numerous times, I am left totally confused- clearly I am not understanding what you've done with this set up. I've basically been told that I cannot recharge my Delta Pro using an inverter while driving because my vehicle's alternator and starter battery are too small for the demands of the size of the inverter that Ecoflow told me is required to recharge the Delta-Pro. Clearly, you have this working, but what you show in your setup, is contrary to everything I've been told by Ecoflow.
First, I was told the Delta Pro must be connected to an inverter that provides 1800 watts of continuous power or it will NOT recharge, and in fact, the inverter might shut down entirely if the power drops below 1800W; therefore my inverter MUST be at least 1800 Watts- yet you're recharging using a 1000 watt inverter. How?
Ecoflow also told me that it is not possible to lower the recharging rate, yet you are recharging at 900 Watts- how are you controlling the wattage input to recharge at 900W as you stated in this video?
Also, you are using Pass-Through charging and running your refrigerator while simultaneously recharging the Delta Pro; Ecoflow told me there is no option to use the Delta Pro to power any appliances while it is receiving an AC charge, how are you doing this? Is your Delta Pro plugged into an AC outlet on your inverter or have you hard-wired these two components together somehow?
What am I missing? Can you please explain? With everything I have been told, it simply will not be possible for me to use an inverter to recharge my Delta Pro using the energy generated by my running vehicle because the alternator in my vehicle is 180 amps and therefore too small to supply the 1800 continuous watts needed to recharge the Delta Pro- yet you've done exactly that, so I really need to understand how you've done this. Can you please help?
Hi, you can definitely change the maximum charge voltage to any watts in 100w increments. We have a Sprinter with an alternator that can handle pulling 80amps while driving - your alternator would need to be the same. Our refrigerator is being run by a Ecoflow River Pro and the Delta Pro charges the River Pro via 12v. It all works - you need to find out how many amps that your vehicle allows to be used for charging the ecoflow, then size the invertor correctly and reduce the charging watts on the Delta Pro. Our Sprinter can handle 80amps - so we have a 1000w invertor (80 x 12 = 960w) and the Delta Pro is set to max charge of 900w. it'll work, you just need the correct settings and equipment for your vehicle
@@GayeNRobert Thank you so very much for the reply, it is very helpful, but what I'm not clear on is how are you keeping your Delta Pro recharged? If you care to read further, I explain what I've been told by Ecoflow's tech support and numerous tech staff from various inverter and battery manufacturers - all telling me that I cannot harness the power of my running engine to keep the Delta Pro charged while I'm driving, and that's exactly what I'm trying to do.
I want to recharge my Delta Pro off of the AC outlet on an inverter that is connected to my vehicle's starter battery while I'm driving, so that I no longer have to search for shore power or an EV charging station (I have not set up a solar panel system yet).
Ecoflow told me that to recharge the Delta Pro from an AC outlet on an inverter, the inverter MUST supply 1800 continuous watts to the Delta Pro or it may not recharge at all and may just shut itself down entirely.
On top of that, I'm told by several mechanics that for the inverter to supply that kind of power to the Delta Pro, my vehicle's alternator must be MUCH bigger than what it is currently,- the standard alternator in my Promaster is 180 amps, I'm being told I need almost twice that.
AND in addition to getting a new, larger alternator, my starter battery which came standard in my Promaster is 95 amp hours and for the inverter to furnish the Delta Pro those 1800 watts, the starter battery MUST be at the very least 400 amp hours and if I upgrade my starter battery to one with 400 amp hours, it will be a specialty battery and would likely be physically larger in size and would not fit into the same location where my existing starter battery is housed, which is under the driver's feet in the floor- there's just no room to spare in that little cubby hole.
Ecoflow also told me that the only option for changing the watts at which the Delta Pro recharges is through the cell phone app and that feature is available ONLY when recharging the Delta Pro at 12 volts- NOT when recharging via AC current.
And while the Delta Pro CAN be recharged at 12 volts while driving by using the vehicle's cigarette lighter port, a full recharge at 12 volts takes 35 hours, so even if I'm just topping off the charge in my Delta Pro, there's no way for me to keep it recharged at that rate because each night when I stop driving for the day and need to use my lights, my computer, or my cooktop, I'd be draining the Delta Pro down and running out of power again- I can only drive about 6 or 7 hours each day, so, 12 volt recharging just can't keep up.
At every turn, I'm being told there's no way to recharge my Delta Pro while I'm driving, without making costly modifications to my vehicle. But unless I'm completely misunderstanding your video, that's exactly what you have accomplished.
So, can you please tell me, how were you keeping your Delta Pro charged up within this inverter system you show in this video?
I cannot always tell if, and when, I'm being advised correctly, but I do know that I've received much conflicting information through the countless phone calls I've made so far.
Again, I'm very grateful for the information you share. This has been beyond frustrating - and to make matters worse, I'm getting on the road in just a couple of weeks as I move out of my home at the end of this month and take to van life full time - a new life after losing my husband. I'm so hoping to have this issue resolved by then so that my transition to this new way of living might be a bit easier- staying powered up means everything to living on the road, so I've got to decide on a solution. Again, many thanks to you for anything you have time to share!
@@GayeNRobert Can you tell me how large is your Sprinter's alternator and how many amp hours is your starter battery in this set up?
I finally got around to trying this, and unfortunately it did not work. The wattage the inverter is putting out must exceed the wattage the EcoFlow is demanding. If not, once that threshold is reached, it will stop charging. So it will work on EcoFlow models that allow the user to set the input wattage but not on models that don't. My older Delta charges at 1000+ watts, so I would need a 1500W inverter, which is well beyond the limits of my Sprinter's alternator.
D. Lowe that's a bummer it did not work for you. I think the important thing is you were not afraid to give it a go and try to figure it out. Thank you for watching!
@@sheri4673 I’m in the same boat with a Promaster 2500 and trying to figure this out. I’m following this in hopes that Robert replies.🤞🏻
@@sheri4673 I owned an older Delta at the time I wrote my earlier comment. I've since upgraded to a Delta Pro. I believe all the newer EcoFlow models allow the user to set the wattage it draws. VS30 Sprinters display a warning message if the charging system is over taxed. From trial and error, I've learned to adjust my EcoFlow according to how hard the engine is working. I never set it above 800W. I have a Renogy 1000 inverter.
Unless you have a dual alternator, it is probably unwise to pull 1800W (or 150 amps). So you don't need a large inverter.
FYI, the Delta Pro can charge simultaneously from the inverter and the cigarette lighter port. I keep it constantly plugged into this port so that it's trickle charging at 70-90W anytime the engine is running. I plug it into the inverter only as needed.
@@igoslomo If you've not seen it yet, take a look at D Lowe's reply to me, he shared some interesting information that was new to me. I'll gladly share with you what I learn. I've posted on a few different videos, I've got to get this figured out as I'm preparing to move into my van full time in a few weeks so I'll be watching the comments closely. I welcome you to do the same if you learn anything.
@@sheri4673 in the link I posted to an installation video there are some great comments... Then she has a follow up video which answers a lot of questions in the comments that were raised.
Hey Robert, where did you connect your 12v power lines for your inverter? Did you make new wires and run them directly to the battery? Is your solution still working well? Ecoflow is now selling an Alternator Charger, but they want $600! Looking for a more reasonable solution.
Amaaaazing lol... thank you... so I guess the red cable goes into the 110v input of the Ecodelta right? also let me ask you... as long as the engine is on, the alternator can provide 1000w? wow... if the engine is off, it will kill the battery quick I guess...
Hi - thanks for your comment. No, the AC cord from the Delta Pro plugs into the inverter. According to Mercedes, the 2022 Sprinter van provide 80amps which is 960watts. We only use the inverter with the engine running.
I like the proportions of the Delta Pro. Looks like areal good fit in the RV.
Hi William - Agreed, it really fits nicely. Quite heavy but not so much that one person can't handle it. Love it so far!
If you're still thinking about getting a Delta Pro, in case this is helpful to you, I discovered with mine that one wants to keep in mind that there are jacks on three sides of the Delta Pro that you need access to, and since it literally weighs 100 pounds, moving it about isn't easy. It needs to be strategically placed so you have room to get all the different power cables in and out as needed. I didn't think of this until after I designated a spot for mine, now I have a bit of a hassle when plugging in various cables due to limited space around the Delta Pro.
