I was really hoping that they had solved the Powerwall priority issue, but it hasn't worked out as hoped for me. Since my car was at 25% after driving it yesterday, I plugged it in last night, set the charge from anything at 60% and CoS at 80%. I had the car scheduled to start charging at 1:00 am. Woke up this morning at 60%, good, then when the solar started generating it filled the car instead of the PWs. Then, around 11:30 it switched to Powerwall priority, but it starting importing power from the grid to charge the Powerwalls. Irritating. I guess I'll have to do charging manually so that the PWs are filled with solar, then plug in the car after they are full. Grrrrrr.
