The Tesla 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, the Tesla 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.

A Tesla 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 the connection to the grid, safely disconnecting your home and starting backup operation during an outage. The Backup Gateway also receives over-the-air updates for the system.

A Tesla Powerwall installation includes at least one Powerwall battery, a Backup Gateway and standard electrical hardware such as circuit breaker panels, conduit, junction boxes, or electrical disconnects as required by your particular installation and local electrical codes.

In some cases, conduit and other electrical hardware can be hidden within the wall for an additional cost.
