Confirm the outage is real, check the Tesla app for battery percentage and Backup Reserve, and identify whether your site is whole-home or partial-home backup.
- 01When grid power fails, wait for the Powerwall/Gateway to transfer the labelled backup circuits. Do not switch off the main supply to test it yourself.
- 02Turn off high-load appliances such as ovens, air conditioners, pumps, kettles and electric hot water to reduce the chance of an overload.
- 03Use only the circuits connected to the backup output. A partial-home system will not power circuits that remain connected to the grid.
- 04Check the Tesla app for battery percentage, Backup Reserve and any overload or outage notice. Do not change Advanced Settings during the outage.
- 05When grid power returns and is stable, leave the system to reconnect automatically. If backup does not start or circuits remain off, call Esena on 1300 239 296.
ImportantTesla whole-home and partial-home backup are different installation designs. Never move a switch or open the Gateway unless the Esena handover specifically labels it as customer-operated.
