Powerwall 3 System Overview
Powerwall 3 is a fully integrated solar and battery system. The home's PV array is connected directly to Powerwall 3, which converts solar energy and stores it for future use.
Powerwall 3 is installed with Backup Gateway 2 to control the system's connection to the grid and monitor home energy consumption.
The following table outlines the key Tesla components in a standard Powerwall 3 system.

Powerwall 3 is an integrated solar and battery system that converts energy from solar panels to be used by the home, and stores excess energy for future use. Every system contains at least one Powerwall 3, with additional Powerwall 3 units and/or Expansion units installed depending on the home’s solar system size and/or energy consumption. |
