What are you refidgerator stats?

Thanks for this as it's just what I was looking for. Another channel tested the inverter loss for the Delta Pro Ultra and found a 7% loss in 12 hours at idle which corresponds to your experience. It's good to hear that there's little to no loss with the inverter off as I plan to use this as whole home backup with no solar. The Anker F3800 lost 23% of its capacity at idle just powering the inverter for 12 hours probably due to its low frequency inverter as opposed to a high frequency type in the DPU. These are factors that should be considered before installing any of the battery units for backup as that's significant energy draw that has to be replenished.

Great idea new EcoFlow delta pro 3 and EcoFlow delta smart Duo fuel Generator 4000 watts test it out on RUclips video 😮👍

Battery Calibaration Recap... 1) Charge DP to 100% 2) Remove ALL inputs/outputs. 3) Turn DP OFF for 1-2 Hours. 4) Trun DP ON. 5) Batteries should now be recalibrated. BMS Calibaration (after battery calibration)... 1) Remove ALL inputs/outputs. 2) Turn DP OFF "then" press & hold ON/OFF button for 3 seconds. 3) BMS should now be recalibrated.

i was wondering if the delta 2 is fully charged and i connect solar panels to it with a load ,does it will take the power from the panels or it will drain the battery then it will charge it up

I've been told that low wattage drain and low wattage charging causes the BMS to get out of calibration.

Thanks for the video: After calibrating your battery you can also calibrate the BMS by removing all inputs and outputs. Turn off the unit then press & hold the on/off button for 3 seconds. Now your BMS is also calibrated.

Hello, Have you tried adding a BMS on your LiFePo4 battery system ?

Why not just use a generator?

Thanks for the video.

Just curious, why did you go with the 12V Vevor and not 24V?

My Delta 2 max does the same thing but only about 10%. Hopefully EcoFlow will address it with an update. I’m running a Powerstream with a max and max spare battery (4kw), the app could do with the ability to remotely put the system to sleep onto an ultra low power mode. Still loving the system though 👍🏻

was there a ground on that connection to the Vevor? I didnt see one, just curious I have a Vevor too and the book didnt show any instructions to hardwire it.

Thank you very much ❤❤❤❤❤❤

Infinite free power.

Vevor? Good luck! That high frequency, transformerless Vevor inverter is not going to last even a year, powering that well pump before you fry the MOSFETs and possibly even cook the insulation off the windings on your well pump's motor. High frequency, transformerless inverters like the Vevor and your Delta Pro are not designed power inductive loads like microwave ovens, well pumps, AC units or large power tools, the MOSFETs and caps simply can't handle the inductive surge currents. You might be able to start and run some high surge loads when these high frequency inverters are new, but every time you fire up one of those inductive loads, you're shortening the life of the MOSFETs in these inverters. Even worse, you don't even have a BMS installed on your battery pack. All it's going to take is for your cells to drop below 2.5 Volts each a few times and you're going to permanently damage your cells. And finally, running your well pump through such a long small gauge extension cord is forcing your well pump's motor to draw more current than it was designed for because of the excessive voltage drop and you're overheating you pump's motor. Basically, you've thrown your money away.

Thank you for sharing your results. Almost 2 days. Can you try the test again with some solar panels inputting power? I'm hoping you can run it indefinitely in case there is no grid power for more than a couple days. What thermometer system are you using?

Blade, you're back. Have you checked out the new EcoFlow DELTA Pro Ultra? That thing is changing the game for sure! I just sold my two Delta Pro's to pick up the new Delta Pro Ultra when it hits the market. What are your long term thoughts on the Delta Pro? The two I had served me very well but I wanted more power and more solar input which the EcoFlow DELTA Pro Ultra has.

nice video! I have 1/2HP well pump. I want this setup.

Can I charge my river 2 with the plug and also charge it with a solar panel at the same time?

You mean a 5,000 Watt low surge. high frequency, transformerless inverter that probably won't last you a year, with repeated use powering that 1 HP well pump. You should have purchased a low frequency, transformer based inverter for emergency use. Hook up an O-scope and you'll see why.

Would a standard gas powered 3500W generator run that well pump? Seems it was drawing under 2500W continuous. Or, would it have run off the delta pro using the 30amp receptacle (with correct plug)?

Thanks for sharing this.

GREAT video!!!!..... Quick question, What if you have one or two external batteries attached and you need to do a reset. Do you leave the external batteries attached while you do the reset or do you disconnect the external batteries? Thanks!!!

Hello, I have an Ecoflow Delta Pro. It's currently plugged into an electrical outlet then give power to some appliances, and I would like to program it so it charges at off-peak hours (from 9PM to 4PM next day) and does not charge during on-peak hours (from 4PM to 9PM). Is there a way to do this other than manually unplugging the Ecoflow Delta Pro? I tried to use Automation on the app and did not see a way to do this. The reason is power consume at off-peak hours gets bill at $0.146/kwh and at on-peak hours gets bill at $0.263/kwh. I would save almost $0.12 for each kwh, but the hassle of plug and unplug it manually.

Mine lost about 40% runtime after a firmware update.

If you install a EcoFlow smart home panel you can charge @ 6500 watts plus what ever solar you can collect at the same time.

Delta pro utilizes the ground from buss panel, it uses ground from upstream. To tie them in can create one of 2 bad issues both of which can be avoided by following delta pro guidelines for independent grounding by utilization of comm port or ev. What you've done is absolutely incorrect and would result in your warranty being void... If buss correctly grounded by one of 2 methods the DP uses upstream ground. Yes, I'm an engineer.

Do you know if the delta pro would run a DAB JET 102M , 220V-240V, 1HP ,5.1A , 1.13kW pump ?

Thanks for the great video.

I set my ac charge limits to 10% and 90% from day one. Smart gens come on at 20% and off at 90%.

In all reality ac and heating is a huge part of life why cant any of you just do a video on how long itll do the ac for

How is everything grounded ?

Did you make your yellow power cords going to your Delta Pro or buy them?

Very nice price on the inverter . If I get it ,I will use your link . How many hours a day do you run the pump ?

Thumbs up! This information needs past along to other EcoFlow owners

Noticed the same, the ecoflow delta 2 uses ~20w to run the inverter which is a significant overhead. Wish these units had a smart inverter. Worth of note is that the usb voltage controller also has ~10w of power use so also isnt super efficient - but more so than the inverter

I tested a 3/4hp well pump 240v running at 2,500w with in-rush watts sometimes close to 9,000watts. 1 delta pro is only 7,200w peak. If your pump can be connected to 240v(some can) and connect 2 DP's with hub for 240v that may work because the peak would be 14,400w peak, but you have to buy another delta pro and $140 hub.

How far are the panels from the battery?

Good info. Can I charge my EcoFlow pro with another EcoFlow pro

Nice, that is what we call a backup of a backup ❤❤❤❤. Thank you

You sent the black power wire to your shop for the kitchen but where did you get the white for the plug. It would have been nice if you could have shown us this part.

Thank you I have had similar issues. Does anyone know a fix for uneven discharge of two DPs with the 240 hub?

I would like to say thanks for doing this video. I just bought an ecoflow delta pro. The house batteries are draining the DP. Curious, do u know how big the house batteries were and number of them and how long it took to charge?

Thanks! Good video. I only would like to comment the noice! It's LOUD! And yeah, I am thinking about one for mainly the shower and the AC.

How well does that AC cool your shop? Have you seen the EF Wave 2 AC/heater?

I figured mine out. Even if your on a 20amp circuit. The Delta Pro is only rated for 15 amps. It will start to cancel out the charge to continue to power load even at a example 1000 watt charge. I wish it maxed out the amp to charge to allow run time to be longer. Lol

I run a old hisense 12k btu with heat unit. After about 10 minutes it's up to 1250-1350 watts. Then as it cools off it will slightly lower. I have ran it in the shed at 95°F and it was pulling 1540 watts! So the intake temp really makes a big difference. With RV air-conditioners. Dometic says 1+ amp of AC per 10°F over 70°F. So a 15K btu rooftop is 13.5 amps @ 70°F , 14.5 amps @ 80°F , 15.5 amps @ 90°F , 16.5 amps @ 100°F , and 17 amps @ 105°F! That is a efficient portable air conditioner! Not quite inverter style but better than the older ones like mine! Lol . How many watts of solar is your array? I just hooked up my last 3 today making a total of 1500 watts finally!

I have also seen that people add something called a "soft starter", which lowers the peak current for items with motors such as pumps and fridges.

It sounds like the software is thinking there was a short circuit because of the surge in amps needed to start the motor. Have you tried updating the software for the battery to the most recent version? I have a similar problem (sometimes, but not alwats) when I run my air fryer on the battery and my 25 year old fridge starts up. The power is well below the 7200 max watts that the Delta pro is advertised to allow, but still trips the circuit. I have actually run way more than 3600 W through the battery without it tripping the circuit. I think the problem is that the surge current required to start up the motor on the fridge is high enough that the Delta pro thinks there is a short circuit. I really don't have a way to measure the surge current, so I don't know for sure that that is the problem or if it actually is drawing more than the maximum amperage. If you have a way to measure the current, I would do that to see what the peak current is when the pumps are first turned on. If it's less than 20 amps, then the pumps SHOULD work when plugged in just to the 20 amp circuits. I really want to know if you get this figured out, and maybe I can do the same thing with my fridge.
