Tesla – Charge on Solar

• Storm Watch
  Powerwall will prioritise charging from any source to prepare for an outage during severe weather events before allocating any excess solar power for vehicle charging.
• Backup Reserve
  If your Powerwall’s stored energy is below the Backup Reserve, your Powerwall will prioritise charging to the set Backup Reserve percentage before allocating any excess solar power for vehicle charging.
• Self-Powered
  With Self-Powered, Powerwall will allow your Tesla vehicle to charge on excess solar until the set charge limit while covering changes in home loads and solar production until the vehicle adjusts its charging power. Once the vehicle has met its charging limit, your Powerwall will charge on excess solar as usual. This is the recommended mode to maximise Charge on Solar operation with your vehicle.
• Time-Based Control
  With Time-Based Control, Powerwall stores energy when energy costs are low and may sell that low-cost energy back to the grid when energy costs are higher instead of using the excess solar energy for Charge on Solar. You may also see this behaviour during Virtual Power Plant or Utility Program events. In most cases, you will see the vehicle pause charging during Peak to prioritise total savings or charge your Powerwall from excess solar while charging your vehicle during Off-Peak from the grid.
• Go Off-Grid
  When Powerwall is off-grid, your Tesla vehicle will continue to charge on excess solar unless Powerwall prioritises saving energy for home use during the outage.

Note: Certain Powerwall modes may not be available in your country at this time.
