Grid Reconnection Took Too Long
When the grid returns, the Powerwall / Powerwall+ system stays disconnected for an extended period of time, keeping loads powered by Powerwall and not the grid
Steps to Troubleshoot
There is a grid qualification delay for each region based on grid code standards. That delay can result in a delayed reconnection to the grid (1 to 5 minutes) after a backup event.
Grid Code | Qualification Time Delay |
---|---|
IEEE1547-2018_UL1741SB-CA-Rule21_2022 | 15 s |
60Hz_240V_s_UL1741SA:2016_California | 60 s |
IEEE1547-2018_UL1741SB-CA-Rule21_LADWP-2022 | 60 s |
All other grid codes | 300 s |
