No way. The future of residential solar is coupled with storage. And the future of storage is in DC coupling, not wastefully inverting solar to AC just to invert back to put it in the battery.
- toomuchtodo 7y agoTesla Powerwalls support either AC or DC coupling, depending on system architecture (grid tie, inverter type, etc). It's unlikely homes will be designed for DC powered loads considering the copper costs (versus conversion losses between current types).
- rory096 7y agoTIL, never seen a DC-coupled PW2 in the field. Looks like it was killed off in 2017.
