Optional: Configure Powerwall 3 Maximum Power / Current Output
The default maximum power / current output for Powerwall 3 is 11.5 kW / 48 A. Beginning with software version 24.20, the power / current output can be configured to one of the following limits during device setup, except where it is limited by the local grid code requirements:
Power / Current Output (AC) | Breaker (Overcurrent Protection) |
---|---|
11.5 kW / 48A (default) | 60 A |
10 kW / 41.67 A | 60 A |
7.68 kW / 32 A | 40 A |
5.8 kW / 24 A | 30 A |
This feature can be used for the following purposes:
- Compliance with utility-imposed requirements on maximum inverter power (for instance transformer capacity limits or interconnection requirements)
- Qualification for subsidies or economic benefits (for instance NEM integrity or SGIP)
- Replacing a Powerwall 2, Powerwall+, or third party solar inverter with a Powerwall 3
