The Delta Pro 3 is easy to set up, connect to your WiFi, update, and configure the app. I shut my house down and even back fed most 120v requirements for about 6 hours and still had more time on battery power if needed. I haven't attached the solar panel yet to see the affect and charge times. Overall, in very satisfied with the initial test.

Arrived quickly and although the outside of the packaging was a little worse for wear, the interior packaging kept the units fully protected. Both the Generator and the solar panel are much heavier than I expected, and I had to have help just getting the generator out of the carton, as I didn't want to destroy the box. The generator is pretty easy to move with the pull-out handle but will probably need to build a ramp to get it in and out of the house for charging. The solar panel was easy to set up and attach, but not sure that just one panel will be of much value if power is out for several days. Guessing it would take 13 hours or more to fully charge. Charge time with one panel is just way too slow. Overall, I am very happy with my purchase and will probably purchase an additional solar panel and/or extra battery.

I plan to use this to run a few of the most important items in my house during a power outage. Between the solar panels and my Honda eu2200i, I can keep a charge on it even during an extended outage. Since the unit is portable, albeit heavy, I can take it anywhere I need quiet, clean power.

State of the Art for portable battery backup. Build quality is excellent. It's very quiet and seems to support higher wattages easily. My primary purpose was to build a modest home backup solution that didn't involve a gas generator. I already have a reliance transfer panel installed which covers several circuits. Looking to expand to other batteries and the Ecoflow dual fuel generator 4000. I have several EcoFlow solar panels and all seem to perform well with this unit. Have not seriously stress tested it yet however very pleased overall.

This is a very good home backup power source. I have only hooked it up to try it, but it did very well. It was able to run my central heat pump unit, refrigerator, several lights and a 65 inch tv with no problem. The only downside I have seen so far is it loses about 5% of its charge every day, so it has to be plugged in all the time and allowed to charge once a day.

I purchased this two weeks ago and the unit had damage on the box and unit with small indented scratch. Ecoflow sent a return label and I have tried to convince them to issue a small credit. I do not want the hassle of repackage and then have to wait on a new unit. Frustration with several calls and emails.

I found the Delta pro three to be a very good solar generator with one exception I would, suggest to buy two 400 W panels because I found that the charging capabilities are there without the additional solar panel it charge slower than I would’ve liked it to

I wanted something to run my pellet stove in outages and had searched for some time. This unit surpasses my hopes. Unobtrusive, looks fine in the living room and does everything advertised and worry free safety wise. It will run my pellet insert for nearly 4 days with additional outlets for anything else such as critical items like the coffee pot. Excellent quality and well thought through like being able to make all adjustments off my phone. Well done EcoFlow.

I was overly impressed by the ease of setup and the overall capabilities of the unit. I have been using it as a backup source for two CO2 50 watt laser engravers. It has outperformed any and all expectations. I am now fully confident that if the power should go out during a lengthy engraving, I will not lose the customers product.

A few weeks ago, I acquired the Delta Pro 3 and am thoroughly satisfied with its form factor and features. The user-friendly application facilitates comprehensive monitoring of the device’s performance. In the near future, I intend to enhance the system’s capabilities by incorporating additional solar panels and batteries.
