Wouldn't it be great if the Tesla charger would talk to the Powerwall
Wouldn't it be better if car never (in normal use) charged from PowerWall? Inefficient to go Grid/PV->PowerWall->EV so better to go both:
Grid/PV->PowerWall->House
Grid/PV->EV
That said, I suppose someone with excess PV, a Powerwall, at work during daylight hours, would want to do PV->PowerWall during the day and PowerWall->Car overnight
But that could be compared with the alternative of having a second EV, at home most days, as the "Battery" for excess PV
