Combining Systems with Powerwall
Powerwall & Solar
Integrating Powerwall and solar is the best way to maximize your system’s value, allowing you to use solar power day and night. Powerwall+ offers a complete, integrated solution for new installations, providing whole home backup with solar, while Powerwall can be integrated with existing solar systems.
Since Powerwall is an AC coupled solution, it is compatible with typical inverters installed on a home energy system. To ensure reliable operation during power outages, at least one Powerwall is required for each 7.6 kW AC of solar included in the backup circuit.
Powerwall & the Grid
When Powerwall is installed without solar, it can charge from the grid if in Backup-only or Time-Based Control to support you during grid outages and to help you save money on your electricity bill. When Powerwall is installed with solar, it will not be able to charge from the grid.
Powerwall & Generators
Powerwall can be added to a system with a backup generator connected with an external Automatic Transfer Switch (ATS) or a Manual Transfer Switch (MTS).
Powerwall is installed between the utility meter and the transfer switch and can charge from solar while the grid is operational. However, the Powerwall and generator are not directly integrated which means Powerwall does not charge from the generator.
In an outage, Powerwall responds immediately and provides backup power before the generator can detect the outage. The generator is turned on only when the Powerwall has low charge, or if loads exceed Powerwall's maximum output.
When grid power returns, the generator will turn off and Powerwall can again charge from solar. If Powerwall is installed with a MTS, manual operation of the switch is required to power the home with the generator.
Powerwall & Electric Vehicle Charging
Powerwall can provide stored solar energy to your electric vehicle through your home electrical panel. However, there is no direct connection between Powerwall and your charging equipment.
Powerwall & Other Systems
Powerwall does not currently work with existing battery systems or other renewable energy sources, such as wind or hydro.
