Stop looking. This is it. After extensive research, I came to the conclusion that EcoFlow is the brand I'd choose for a solar generator. Take my word for it, get one.
I absolutely love my new Ecoflow max2 generator. I've charged it up , but haven't use it yet. Will use during a power outage. Mostly to keep my refrigerator going. A few lights and tv.
I bought this and installed it into my daughter's bus. (Schoolie conversion) It is what we wanted. The only complaint that I have is the way the cable comes out the side. you cannot stack anything next to them within a foot. The wave has a nice 90 degree cable that goes between the battery and AC but the Delta 2's cable sticks about 6 inches out the side.
We purchased the Delta 2 Max as an alternative to an overhaul of our RV's electrical system. We've used the unit a couple of days and it looks like it will be sufficient to enable us to boondock for two to three days. The case is sturdy, well made and not too heavy given the performance of the components. The app / smartphone interface is great.
I bought 2 of the pro max 2's , like them will work for my green houses during the summer but......will only run the 1500 w heater for about 2 hours. NOT ecoflow fault it's mine did not do my research heater draws 12.5 amps on full setting so 2hrs at that current is not so bad. would buy the pro max 2 again may even get the batteries for the unit.
