Modes of Operation With Solar

Powerwall is customisable and can operate in a number of modes controlled directly from your Tesla mobile app. This article describes the operation of Powerwall in these modes.

If your system is not paired with solar, see Modes of Operation Without Solar.

Operation summary
Powerwall is able to prioritise charging and discharging based on its advanced software and intelligent forecasting. It can save energy capacity to charge from a higher priority source later in the day. Similarly, it will maintain energy to discharge to a higher priority destination later in the day. The following table shows Powerwall’s energy dispatch priority based on operating mode.

Home energy usage
Any Usage - Any energy being used by the home
Net Usage - Energy used by the home that is not currently being offset by solar

Solar production
Any Solar - Any energy being produced by the solar system
Excess Solar - Energy being produced by the solar system more than the home is currently using
