In an experiment today, my PoweWall/Gateway setup would not start without Grid Power.
Here is the sequence that I followed to do a cold restart of my system that consists of a 125A breaker on my main panel feeding a gateway connected to a backup panel and a generation panel with 9.9 kW of Solar and 2 PW2's:
Here is the sequence that I followed to do a cold restart of my system that consists of a 125A breaker on my main panel feeding a gateway connected to a backup panel and a generation panel with 9.9 kW of Solar and 2 PW2's:
- Switched the 0/1 switches on the PW2's from 1 to 0. The PW2's were at 99-100% charge and their green light bar stayed on.
- Opened the 125A breaker on the main panel.
- The lights on the Gateway and the PW2's stayed on.
- Waited about 10 minutes. PW/Gateway lights stayed on, but there was no switch to backup power; the power stayed off.
- Pushed the "reset" button on the Gateway and held it down for about 10 seconds. All the PW/Gateway lights went off.
- Waited about 5 minutes.
- Flipped PW2 switches to On/1. Nothing happened.
- Waited about 5 minutes. Nothing happened.
- Closed 125A breaker to feed Gateway/PW system with grid power. PW system restarted.
