I have solar with two Powerwall 2 batteries. When I go into the Tesla app under the ‘Customize’, I don’t see an option for Backp or to set a Reserve level. I’ve noticed when I run the wizard, a message comes up that says ‘No backup capability detected. No synchronizer detected’ My solar installer has no clue. Tesla has bumped it to the level 2 team. Anyone else experience a similar issue?
