Easy to Add to Get Additional Capacity and plugs right in!

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

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

I don't even notice when I lose power. Changes so quickly nothing misses a beat.

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

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

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.
