Anyone know from experience what happens in a prolonged outage when the grid is out and powerwall 2s are drained of charge? [Defined as 0% available per the app.]
Will solar production/inverters be able to start back up using residual sub-zero-percent charge in the idled powerwalls?
Can inverters bootstrap themselves with sufficient solar production and charge the powerwalls in a prolonged grid outage? Safely with a Tesla gateway?
Or, in a prolonged outage does some minimum of the remaining power need to be protected by the user by turning off all loads except the inverters?
Worst case.. use an DC-AC car inverter with a running car to get the solar inverter to do some solar production?
