Getting the wall connector now could be worth it. It’ll make the whole setup smoother, and he won’t have to worry about upgrading later when he adds the backup system.
I'm seeing a "HVBATT_a174" error at Superchargers after that DC charging update! Level 2 works, but Superchargers are a no-go. Tried multiple locations, but nada. Is it a glitchy update or am I the only one dealing with this?
