Enroll in California Title 24 JA12 Compliance
A single Powerwall 3 has a maximum cycling capacity of 13.5 kWh; the user can decrease cycling capacity by configuring the Powerwall's Backup Reserve, which reserves a percentage of the battery for backup events.
To comply with JA12 requirements in California, the Powerwall 3 site must have a minimum cycling capacity of 5 kWh. To
ensure the home remains in compliance, the JA12 Special Program can be enabled during device setup. With this feature enabled:
- The user can still set their Powerwall 3 Backup Reserve to Max Backup (100%) when needed
- The Powerwall system will only remain in Max Backup mode for 72 hours
- After the 72 hours have elapsed, the system will automatically reset to the previous Backup Reserve setting which allowed a minimum 5 kWh cycling capacity
To enable the JA12 Special Program:
- From the Settings screen, select Advanced Settings.
- Select .
- Select Enroll JA12 Special Program.NoteOnce this setting has been enabled, it is locked and can only be modified by Tesla Installer Support.
