Troubleshooting - Tesla Powerwall 2 AC 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.
WARNING: Do not open the deadfront cover inside the Backup Gateway. Exposed wiring
can present a risk of electrical shock.

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
On (solid)
On (flashing)
On (pulsing)
Off

If it is not possible to communicate with the Backup Gateway through the Tesla app,
ensure that the home Internet connection is working.

Tesla Support may direct you to restart the Backup Gateway by pressing the RESET
button for at least one second. NOTE: if your system is disconnected from the grid,
Powerwall will stop providing power while the Backup Gateway is restarting.

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.
Turning off the system
