Basic Troubleshooting for Tesla Powerwall 2
Basic Troubleshooting for Tesla Powerwall 2
If the system is not working correctly, perform the following steps.
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 enables 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.
- 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).
In 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.
4. Wait for at least one minute.
5. Turn the AC breakers back on.
6. Turn on Powerwall.
Additional Troubleshooting Tips for Backup Systems
- If a brownout or blackout is experienced during backup operation, reduce the loads and check that the load breakers have not opened.
- If it is necessary to restart the Gateway, Tesla support may direct you to press the Reset button on the device.
- If it is necessary to manually disconnect/reconnect to the grid, Tesla Support may direct you to operate the manual override switch on the Backup Gateway.
