Powerwall is customizable 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 prioritize 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.
