About Tesla Powerwall

Powerwall is a rechargeable home battery system designed to maximize your home’s energy independence. That means seamless backup and a smaller carbon footprint for your home, and potentially savings on your electricity bill. Powerwall is an intelligent system that can be customized to your energy needs, with the ability to charge from solar or from the grid so energy is always available on demand.

Powerwall gives you the ability to store energy for later use and works with or without solar to provide key security and financial benefits. Each Powerwall system includes at least one Powerwall and a Tesla Gateway, which provides energy monitoring, metering and management for the system. The Backup Gateway learns and adapts to your energy use over time, receives over-the-air updates just like the rest of Tesla’s products and is capable of managing up to ten Powerwalls.

Powerwall + Solar

When the sun rises, solar begins powering the home. When additional power is required within the home, the home can pull 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.

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