Customers can use their Tesla app to update the following settings:

• Backup Reserve determines how much of Powerwall's stored energy will automatically be saved for backup power. The default Backup Reserve is 20%.
• Operational Mode:
  • Self-Powered is an operational mode that allows Powerwall to store solar energy not used during the day to power the home at night. This is the default operational mode.
  • Time-Based Control (also referred to as load shifting) is an energy optimization technique that can help the customer maximize savings through smart charging and discharging of Powerwall.

The installer can also change these settings during device setup:

1. From the Settings screen, select Advanced Settings.
2. Select Operation Settings.
3. Adjust the Backup Reserve and/or change the Operation Mode as requested by the customer.
