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

Bate rey starting to fail, cable not working propretly

I bought two of these and will buy another in the future. They function perfectly.

Works like a charm, hassel free, not ever worried about blackouts

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.

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.
