Powerwall System Design

Components that make up a Powerwall System

A 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.

Designing for Whole Home Backup

When designing your system, Tesla will recommend the number of Powerwall units needed to back up your entire home (whole home backup). This means that during a power outage, your Powerwall system would be able to support all your appliances. You can then add more Powerwall units to keep your house operational during longer outages.

If you order multiple Powerwalls for your system, they can be mounted as single side-by-side units on a wall or on the floor, or stacked front-to-back (up to 3 deep per stack) and mounted on the floor only.

Side-by-Side Mounting

When mounted side-by-side on a wall, Powerwall units must have enough clearance on each side for electrical connections and proper ventilation.

Front-to-Back Mounting

When stacked front-to-back, Powerwall must be floor-mounted and the stack must be anchored to an adjacent wall, and the Powerwall units must be joined together with Powerwall Stack Kit hardware.

Stacking Larger Powerwall Systems

For stacked systems with more than 3 Powerwalls, separate stacks of 3 units should be installed, with each stack attached to a wall.
