Powerwall 3

With Solar

When the sun rises, solar begins powering the home. When additional power is required for the home, the home can pull it from the utility grid.

Powerwall is charged by solar during the day, when solar panels are producing more electricity than the home is consuming. Powerwall then stores that energy until the home needs it, such as when solar is no longer producing at night, or when the utility grid is offline during a power outage. With Tesla, when your Powerwall system changes status, such as the utility grid going down or offline, you can expect to receive notifications from the Tesla app.

When the sun comes out the next day, solar recharges Powerwall so you have a cycle of clean, renewable energy.

Without Solar

If your electricity rates vary throughout the day, Powerwall can charge when your utility’s electricity costs are low and discharge when electricity costs are high, generating automatic savings. Powerwall will also provide seamless backup power by detecting grid outages and automatically becoming the home's main power source.
