AFAIK, Powerwall setup only indicates if you have solar or not. In the USA, if you have solar, it will only charge the batteries from solar. Even if you waive off ITC or other incentives that require solar charging, I don't think Tesla provides a way for you to charge the batteries in a more flexible manner. I think the only way to charge from the grid is to tell the system that you don't have solar, but then it's backup and time shifting only.Does TBC know if one is (standalone vs paired) storage to allow grid-charging? Or if one is taking the ITC which then requires 100%-only renewable charging?
Sometimes, it would be nice if Telsa is a little less black-box.
