Troubleshooting
If the system is not working correctly, perform the following steps.
CAUTION
Powerwall+, the Backup Switch, and the Backup Gateway are not user-serviceable and must be
repaired by a Tesla Certified Installer.
Warning
Do not open the door of
the Powerwall+ Solar Assembly, nor 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) | Powerwall+ idle, no faults |
| On (fading) | Powerwall+ enabled and charging or discharging OR generating solar energy |
| On (flashing slowly) | Powerwall+ faulted at < 30 V solar (safe) |
| On (flashing rapidly) | Abnormal fault present |
| Off | Powerwall+ not enabled or switched off |
If it is not possible to communicate with Powerwall+ through the Tesla app, ensure that the home Internet connection is working. If the home Internet connection is working and communication through the Tesla app is still not possible, see Connect Powerwall+ to Wi-Fi for instructions to update your Wi-Fi connection.
If Powerwall+ is 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 additional 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 Enable switch to the OFF position.
- Turn off any additional Powerwalls by setting the On/Off switch to the OFF position.
- Turn off the AC breaker to Powerwall+ and any additional Powerwall AC breaker(s).
- If the system has a Backup Gateway, turn off the AC breaker to the Backup Gateway (for whole-home backup systems, this may be a breaker inside the Backup Gateway).
- Wait for at least one minute.
- Turn the AC breaker(s) back on.
- Turn on Powerwall+ and any additional Powerwalls.
