Troubleshooting
If the system is not working correctly, perform the following steps.
CAUTION
Powerwall and the Gateway are not user-serviceable and must be
repaired by a Tesla Certified Installer.
Warning
Do not open the deadfront cover inside the Gateway. Exposed wiring can
present a risk of electrical shock.
Check the LED on the right side of Powerwall to determine its status:
| LED State | Indication |
|---|---|
| On (solid) | System idle, no faults |
| On (fading) | System enabled and charging or discharging |
| On (flashing) | Fault present |
| Off | System not enabled or switched off |
If it is not possible to communicate with the Gateway through the Tesla app, ensure that the home Internet connection is working.
If the Gateway and Powerwall are both unresponsive, it may be necessary to turn off or power cycle the system. Note that power cycling the system must be done in the proper sequence as defined below.
Warning
On Powerwall systems
with interconnected solar, always turn off the solar inverter or disconnect the
solar source before turning off the Powerwall unit.
- Turn off Powerwall by setting its On/Off switch to the OFF position.
- Turn off the AC breaker to Powerwall.
- Turn off the AC breaker to the
Gateway (for whole-home backup systems, this may be a breaker inside the Backup
Gateway).NoteIn some cases your installation might only have a fuse. If there is no AC breaker for the Backup Gateway, please contact a Tesla Certified Installer to install an AC breaker or AC isolator for you, as required in the installation manual. Under no circumstances should you pull a fuse in an attempt to switch off the system or test backup functionality.
- Wait for at least one minute.
- Turn the AC breakers back on.
- Turn on Powerwall.
