Power everything.

Protect your home against outages.

When a power outage occurs, Powerwall automatically detects the outage and instantly powers your home with stored backup energy. If a storm is forecast, Storm Watch automatically charges your Powerwall to 100% to ensure you’re prepared.

Powerwall is also expandable to ensure you have whole home backup for even the most energy-demanding appliances and systems.

A cost-effective alternative to fuel-powered generators.

Powerwall emits no exhaust or harmful fumes. Compare that with traditional generators, which are expensive to operate and produce harmful fumes while using fossil fuels to provide backup power during an outage.

Powerwall can also help reduce your monthly electricity bills using time-of-use rates, net metering, and virtual power plant grid support programs. Plus, Powerwall qualifies for the 30% investment tax credit.

 

Simple design. Fast installation.

With a compact design and fully integrated solar inverter, Powerwall can be installed quickly and it requires minimal space.

Powerwall can be installed indoors or outdoors, wall-mounted or floor-mounted, paired with solar or without, and it operates in both very cold and hot temperatures.

Smart energy control with the Tesla app.

Each Powerwall system is equipped with energy monitoring, metering and smart controls through the Tesla app, so you can control your system from anywhere.

Customize your setup with innovative options like charging when your utility’s electricity costs are low and discharging when costs are high.

With Powerwall and solar, you’re in control.

Get greater control over your home’s energy when you pair solar panels with Powerwall. Use solar energy when you need it instead of always relying on the grid and worrying about high electricity rates or sudden outages.

When the sun rises, solar will begin powering your home. When additional power is required, energy can be pulled from the utility grid. At night, Powerwall can provide the clean energy you've generated from solar during the day.

30% federal tax credit.

As of 2023, Powerwall qualifies for a 30% Residential Federal Investment Tax Credit, regardless of power source. Please consult your tax professional for your specific situation.
