Tesla POWERWALL 2 AC - Troubleshooting Backup Systems

10 Powerwall Owner’s Manual
Troubleshooting
If the system is not working correctly, perform the following steps.
CAUTION: Powerwall and the Backup Gateway are not user-serviceable and must be
repaired by a Tesla Certified Installer.
• If a brownout or blackout is experienced during backup operation, reduce the loads and
check that the load breakers have not opened.
• Check the LED on the right side of Powerwall to determine its status:
LED State
Indication
On (solid)
Powerwall enabled/Communication with Backup Gateway
On (flashing)
Powerwall enabled/No communication with Backup Gateway
On (pulsing)
Powerwall enabled and charging or discharging
Off
Powerwall not enabled or switched off
• If it is not possible to communicate with the Backup Gateway through the
My Tesla app, ensure that the home Internet connection is working.
• If the Backup Gateway and Powerwall are both unresponsive:
1. Turn off Powerwall by setting its On/Off switch to the OFF position.
2. Turn off the AC breaker for Powerwall.
3. Turn off the AC breaker for the Backup Gateway (for whole-home backup systems,
this may be a breaker inside the Backup Gateway).
4. Wait for at least one minute.
5. Turn the AC breakers back on.
6. Turn on Powerwall.
• If it is necessary to manually disconnect/reconnect to the grid, Tesla Support may direct
you to operate the manual override switch in the Backup Gateway.
CAUTION: Do not remove the protective label or operate the manual override switch
unless directed to do so by Tesla Support. Improper operation of the manual override switch
may damage the unit.
