How Powerwall Works

Powerwall gives you the ability to store energy for later use including backup power for your whole home. Each Powerwall system is equipped with energy monitoring, metering, and smart controls for owner customization using the Tesla app. The system learns and adapts to your energy use over time and receives over-the-air updates to add new features and enhance existing ones.

Powerwall & Powerwall+

Powerwall is a rechargeable home battery system that can be installed with solar. A Powerwall+ contains additional features including solar integration that enables cleaner installations with less equipment.

Integrated energy metering will help you accurately monitor your solar production and home energy consumption for precise, real-time insight into your home energy consumption. Powerwall+ is able to intelligently power heavy equipment, and direct solar integration improves solar recharging during power outages, resulting in a better backup power experience than ever before.


With Solar

When the sun rises, solar begins powering the home. When there is sufficient solar and battery power available, the Tesla system zeroes grid usage. 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 whenever solar panels are producing more electricity than the home is consuming. Powerwall stores the excess 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. When the Powerwall system changes status, such as the utility grid going down or offline, you 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.
