About Powerwall

Powerwall 2 AC is a fully-integrated AC battery system for residential or light commercial
use. Its rechargeable lithium-ion battery pack provides energy storage for solar self-
consumption, load shifting, o -grid use, or backup. The Backup Gateway controls the
operation of the system, allows remote monitoring of energy usage, and controls
interconnection with the electrical grid, automatically managing the transition to and from
backup operation.
A Powerwall 2 AC Backup system can provide whole-home backup or partial-home backup.
In a whole-home backup system, the Backup Gateway is typically installed
between the electrical service entry and the main switchboard:
