1.11 March 7, 2025
1.10 October 24, 2024
  • Updated Design Considerations to reflect that Powerwall 3 can be configured to have an off-grid maximum continuous discharge power of 15.4 kW if installed with an 80A breaker and appropriately sized conductors
1.9 October 9, 2024
1.8 September 4, 2024
1.7 August 28, 2024 Updated Design Considerations and Metering Considerations to reflect Tesla Remote Energy Meter as an option for metering non-backup loads and/or AC-coupled solar
