Best praise vs top criticism for EcoFlow DELTA 2
Best Praise
+8 pts“I got my delta 2/EB set almost two years ago and then upgraded my generator to a dual fuel inverter champion model when they went on sale. I also got 4 used 360w residential panels ($100/panel from FB marketplace) later that year. My goal was to have all my power tool batteries and ego lawn equipment running off solar. It’s over paneled for the 500w the D2 can accept but it works well. It was nice to play around with the solar but the whole setup really showed its value when we had a massive storm last July. My house was without power for 5.5 days and there were neighborhoods around us that went over a week without power. With the delta 2/EB/solar setup I could run my generator for 2 hours to recharge the system to full (also ran an extension cord to my neighbors to let them run their fridge and freezer). The battery bank would run my 2 fridges, a chest freezer, fiber gateway/mesh router, and charge my power tool batteries for the whole day until around 9 pm we’d run out of power. Run the generator again for another 2 hours and top everything off for the night. I never had to leave my generator running unattended and we saved so much fuel by not having it running constantly. Being able to lock the generator in the garage gave me piece of mind that it wouldn’t get stolen without a lot of work. Having 2 ryobi battery powered fans we could run all day and a working ice maker made life without AC actually pretty comfortable. And not being reliant on the overloaded cell towers for internet/communication meant life was pretty easy compared to our neighbors. It was lucky the fiber lines didn’t get take out by the storm but most of my neighbors had no idea the network was still up. IMO using the medium sized solar generators as a piece of a hybrid system (inverter propane/gas generator, solar panels, solar generator) is an overlooked option. You can use a smaller more efficient ICE generator to charge your batteries as needed, save a ton of fuel, run in silent mode for 80% of the day, and have constant power.”

+7 pts“I have found my Ecoflow unit to be a good value for short outages, limited load situations. (I have a River 2 Pro) It runs my fridge for 8+ hours, and easily charges all our portable electronics many many times. I pull it out long before I even consider starting the generator. They seem to make good stuff.”
