Step 13. Finish Installation and Register the System

1. After installation is complete, remove the protective film from Powerwall.
2. Remove the plastic straps from the left and right side covers by cutting them and carefully
pulling them through the slots in the covers.
3. If you have not already done so, register the system by visiting
4. Leave the Powerwall Owner's Manual with the owner of the newly installed system.


If Powerwall is not working correctly, perform the following steps:
Check the status of the LED on the right side of Powerwall.
The LED indicates status as follows:
LED State
On (solid)
On (flashing)
On (pulsing)
If it is not possible to communicate with the Backup Gateway through the My Tesla
app, ensure that the home Internet connection is working.
Ensure that Powerwall is correctly connected to the Backup Gateway, based on the
wiring diagrams above and site design information.
WARNING: Before opening the Powerwall wiring compartment, make sure to
switch off the AC breakers for Powerwall and the Backup Gateway, switch off the AC
disconnect (if applicable), and switch off Powerwall.
WARNING: Switching off Powerwall disengages the Enable line but does not
disconnect AC voltage. High voltage may be present on the AC connection leads
unless the Backup Gateway, any associated circuit breakers, and the AC disconnect (if
applicable) are switched off.
If a brownout or blackout is experienced during backup operation: reduce the loads
and check that the breakers have not opened.
If Powerwall does not operate and the ambient temperature is high, increase ventilation
if needed.
