System Design
Powerwall 3 is a fully integrated solar and battery system that stores energy from solar production. It converts energy
from solar panels, and its rechargeable battery pack provides energy storage for solar self-consumption, load
shifting, or off-grid use. Powerwall 3 is installed with Backup Gateway 2 to control the system's connection to the
grid and monitor home energy consumption.
