I can tell you that the Solar Edge inverters do not support AC coupling, as their reps told me at the NABCEP CE conference…
I have seen pictures of some Solar City battery systems that use an XW as the inverter.

The product mostly seems like a toy for wealthy people but nonetheless I would like to be educated in how it works. There is mention that the battery pairs with Solar Edge inverters which makes sense because both the Powerwall and Solar Edge work off of ~350 VDC. But, I can’t figure out how off grid operation would work during power outages. Maybe another battery inverter like a Schneider Conext is required? Any thoughts on this product for better or worse? Best, August
