Tesla Power Wall
A Powerwall system consists of at least one Powerwall battery and a Backup Gateway. The Backup Gateway provides energy management, metering and monitoring functions for Powerwall. It controls connection to the grid, safely disconnecting your home and starting backup operation during an outage. The Backup Gateway also includes communication functions for up to 10 Powerwall units, and receives over-the-air updates for the system. Powerwall is a rechargeable home battery system that stores energy from solar or from the grid and makes it available on demand. It can power your home during the night, or back up your home in the event of a power outage. With its built-in battery inverter, Powerwall is compact and easy to integrate into your home. As with all Tesla products, new features will be added to Powerwall with over-the-air updates.
