It's a great alternative to my gas generator. It powers my entire house. I'm glad I got it. It's come in very handy during our power outages.

    • Major flaws, terrible support, beware
Style: DELTA Pro Ultra+Extra Battery
Customer for almost 3 years now. The battery system is supposed to come online instantly (20ms) when operating in emergency power mode and I can tell you that that does not work. It used to but it does not work. And support does not answer you (unless you are a new customer). And at this point I'm ngl I'm pretty frustrated with being sold (many many thousands of dollars now plus installation) something that doesn't work as intended. EXTREMELY expensive paper weight. If this gets fixed I might update but I have been ignored multiple times and that tells you they don't care. ... show more

I have the Delta pro ultra with three extra batteries, living off grid in a box truck and a custom engineered RV trailer. Located in Quartzsite, Arizon, Boon-dock living with (16) 250 W solar panels. I have a 7 ft.³ deep, freeze, refrigerator, a 12,000 BTU mini split (22 see2), Starlink, eight high-end night vision cameras, running 24 hours a day, as well as a Mac M4 studio computer operating at least eight hours a day. Thermostat is set at a cozy 72° during the day and 68 at night I found that it is most effective if you were located in extreme heat to have the batteries within the air-conditioned space. The heat produced by the batteries charging is minuscule if you have a mini split. ... show more

    • Easy to setup and works

Very well packaged, everything works as described. Have not gotten an outage yet but tested the system to run the fridge and all is good. Setup and application installation was straightforward. Updated the firmware and seems to hold charge very well.

    • It Works But With Serious Flaws
Style: DELTA Pro Ultra+Extra Battery
Bought this with 2 batteries for vanlife. Got it on sale and used prime card for more savings. Works as expected, runs my window AC, air fryer and everything else fine. The only issue is that charging from an EV charger never reaches 7200w. It only goes up to 6100w. An extra 1200w would be nice, thats 10% of extra charge (since i have 2 batteries) per hour. Update: Been a few months now so... 1. The charge controller makes a clicking sound when it detects power from solar panels, not loud or obnoxious but something to consider i guess? It clicks on/off in the mornings and evenings due to low solar irradiation. 2. The battery level indicator is only accurate for a few days. I think the batteries have to be charged to 100% once in a while to keep it accurate. I currently have it set to max discharge 5% and max charge 95%. The amount of power I use from an EV charger and the percent on the display is off significantly, so when I notice that, i just charge it to full. 3. The LCD display is constantly turning off/on when power is being drawn or stops being drawn. I wish there was a way to permanently turn it off since I live in a van (soon a truck camper 😬) and the bright as light is annoying af. 4. The standby power consumption is consistent with some youtubers measurements. I'm estimating it to be 5-10% per day. That is a big deal for vanlife but the 2 mppts, AC and EV charging makes up for it. My next camper will probably have 1600-2000w worth of panels. I currently have 1040w which would be fine if I didnt run AC or electric heat but I spoil myself. 5. While driving, if your panels become shaded temporarily, the input will go to 0w before going back to normal. If you're in shade too long, say under a lengthy tunnel or bridge or a row of trees, the charge controller won't start charging immediately after you're back in the sun. It takes several minutes, I haven't timed it. This sucks. That's all I can think of for now, hope it helps. Update 2: I just realized the inverter spits out a ton of heat while charging. In my truck camper now and I find that it heats up the entire space really quickly. This might not be the best product for van/camper/rv living since the AC has to fight all the heat this thing produces. May be in the winter I'll have a different opinion...? Update 3: I noticed when charging, the battery % jumps from the mid 50% up to 70% or so. Kinda weird how it can be so innaccurate, even after the update that supposedly fixed the problem of it not displaying the correct battery level. Sometimes I feel like the battery % that's displayed is totally off...seems like a serious flaw when trying to run this on a small solar setup. When the battery level that's displayed is too low and it hits your max discharge level, you won't be able to use it even if you suspect the system is wrong. I'm thinking about selling this thing and going back to building my own system. 🤷 Update 4: Let the system drain to about 4% then charged it fully. It only charged ~8 KWh to get to 100%. Which means about 3500-4000Wh was left, likely in the second battery. The voltage reading must be off so that's probably why it thinks there's only 4% left. Such a disappointment. ... show more

    • Back up strategy
Style: DELTA Pro Ultra+Extra Battery
Review Image by Marcellus
I researched various backup scenarios and talked with a few solar contractors and implemented a partial panel strategy with this EcoFlow setup with a smart panel. I am a retired master electrician so I did the installation myself. I am impressed with the build quality and app functionality. Not so much with the documentation as it left several questions open on various ways to implement use of the equipment, such as various recharging methods. While several ways are mentioned the devil is always in the details. The docs strongly suggest using a qualified contractor to do the installation. So perhaps those questions could be answered as well as a consultation on equipment to use for a given strategy. All in all I am happy with everything. We will see in time if any problems develope. ... show more
