EcoFlow Delta Pro 3600W Smart Extra Battery with Solar Generation, Grey & Black

I am totally off grid 2800 square-foot house after the house is warmed up, Eco Flo, pro extra battery I can run one complete day, the furnace and Full size fridge, lights Fireplace blower and use about 50%. You don’t want to take it down below that because it’s gonna take about four hours to charge it. I have another set Eco Flo pro an extra battery. that I use while the first battery is charging effectively, I could take both batteries down to 20% and live for four days with no charging excellent product remember, you don’t wanna get the system too big it’s gonna take too long to charge you from a generator.

Couldn't do without my extra batteries for my delta pros. love that they now have the new 2m flat link cable, makes setup so much easier.

I have the Delta pro and one extra battery at the moment and I'm looking to purchase a second battery. I like everything about the units except what another reviewer said, the cable to hook the extra battery up it's so short the extra batteries have to be on the two sides of the Delta pro power station. I have them in a small laundry room on a shelf and I wanted to put the extra battery on the shelf but since the cable is only 3.2 ft or meter long I can only put one battery on the shelf above the Delta pro power station. So if I want to add another battery it will have to be on the floor right next to the power station for the cable to reach. Unfortunately then my dryer door will not open more than a third. They said I could buy the 16-ft cable with the smart battery adapter which is way too long. Can't we just get a seven or eight foot cable I hear a lot of people with the same issue. I'm sure 16 ft cable plus smart battery adapter isn't cheap either. And then there's 16 feet of cable to have hanging around. That's the only reason I took one star off everything else is great but I'm in a bind hooking up the extra battery with one option, buy 16 ft cable with extra battery adapter. I called EcoFlow they have no intention of making a 8-ft cable or just one that would actually work. The ease of use is very easy but I took a star off because I had to take one off because no one thought of making a cable long enough to stack the batteries. And it's not some cord you just go in the store and buy one.

My delta pro after two months of use will no longer charge with solar and the LCD won't even turn on it still charges with the gen but I can't even connect to it

Glad i got the extra battery. Great product now the wife won't have to mess with the gas generator when im not at home.
