Delta Pro 3 Price and Specs - Should You Buy One?

I completely agree with the backward compatibility issue. They could have developed an adapter so the new products would connect directly to the Smart Home Panel 1.

They abandoned, those of us, who made them wildly successful and the "no backwards compatibility with the DP & SHP1 is going to be an issue. Sure, it's backward compatible with the Extra Battery but the original Delta Pro has become a boat anchor that they clearly aren't planning to support. The 150V limitation still exists when others have proven they can do 400=500V in these all in one inverters.....
