This is truly a plug and play solution. It's extremely intuitive, easy to use. I am using it offgrid with a 3200w roof mount solar system. I love being able to see my power usage in real time and adjust accordingly. It was worth it to me to pay more for this all-in-one system vs saving some money stick building one...it seems safer to me vs running large gauge wires in attempt to do my own inverter/charge-controller/battery-bank. I do wish extra batteries were more affordable.

My full off-grid solar power system

I own two Delta Pro Ultra's with two batteries each. My application is in a rural off-grid location. I have been able to power my 700 sq. foot cabin entirely, with two solar arrays @ 3600 watts each and an EcoFlow dual-fuel backup generator if we encounter insufficient light (which isn't very often)! We have experienced matchless performance, scalability, flexibility. It cools/heats itself in temperature extremes-simply awesome!

I love this system. With the home panel, there is no flicker when the power changes. I bought a unit with 2 batteries and it runs my most of my house. I plan to add batteries and solar this year.

Plug and play to be exact. The entire DPU experience has been positive.

Looks very good, but batteries are running about 15 degs F hotter than Delta Pro batteries.

Have a 4 Battery DPU setup and I was absolutely floored at how easy it has been to add batteries to the DPU. The hard part is getting it out of the shipping box (you really need 2 people to move the batteries). Just turn off the DPU, set the extra battery on the existing stack, plug in the cable and turn it back on. The app finds the connected battery and voila you got an extra 6kWh of capacity. EcoFlow really knows how to do things simple when it comes to installation and setup! Plugged in my EV charger via the xStream cable and in about an hour had the new battery fully charged with the others in the stack. Yes it’s pricey and hope the price continues to come down.
