Powerwall+ is an integrated AC battery system that stores energy from solar production. Its solar inverter converts energy from solar panels or Solar Roof, and its rechargeable lithium-ion battery pack provides energy storage for solar self-consumption, load shifting, or off-grid use. Powerwall+ is installed with either Backup Switch or Backup Gateway 2 to control the system's connection to the grid and monitor home energy consumption.

Whole Home Backup System

A Powerwall+ system for whole home backup is designed to store energy from the grid or solar, and power the entire home during a grid outage.

Partial Home Backup System

A Powerwall+ system for partial home backup is designed to store energy from the grid or solar, and can power some home loads during a grid outage. These loads are selected during the system design phase, and the installer configures the system at installation to exclude all other loads from backup.
