If Powerwall is not working correctly, perform the following steps. If the issue persists, contact the
Tesla Energy Authorized Reseller who originally sold the Powerwall.
• If Powerwall refuses to operate: check the temperature in the room and increase ventilation if
needed.
• If the inverter and Powerwall are both unresponsive: switch
o the breaker for the inverter,
wait for at least one minute, and then turn it back on.
• If a brownout or blackout is experienced during backup: reduce the loads and check the
breakers.
• If it is not possible to communicate with the inverter through its portal: ensure that the home
Internet connection is working.
• Check the inverter's screen or dashboard to see if it lists any alerts or problems with
Powerwall.
• Follow the troubleshooting steps outlined in the inverter manual.
