Powerwall 3

Power Everything

­—
Powerwall 3 is a fully integrated solar and battery system, designed to accelerate the transition to sustainable energy.
Customers can receive whole home backup, cost savings, and energy independence by producing and consuming their own
energy while participating in grid services. Once installed, customers can manage their system using the Tesla App to customize
system behavior to meet their energy goals.

Powerwall 3 achieves this by supporting up to 20 kW DC of solar and providing 11.5 kW AC of continuous power per unit. It has
the ability to start heavy loads up to 150 A LRA, meaning a single unit can support the power needs of most homes. Powerwall 3
is designed for mass production, fast and efficient installations, easy system expansion, and simple connection to any electrical
service.
