Power Your Home, Save Money

Powerwall is a compact home battery that stores energy generated by solar or from the grid. You can then use your stored energy to power the devices and appliances in your home day and night, during outages or when you want to go off-grid. With customizable power modes, you can optimize your stored energy for outage protection, electricity bill savings and more.

How it Works

Store Extra Energy

When your solar system generates more energy than you need, you can store the extra energy with Powerwall and save it for later. Powerwall can also recharge from the grid when utility prices are low.

Use Energy

Your stored energy is available whenever you need it—during the day, at night or when an outage occurs. A Powerwall system can power your entire home, including your heater or A/C, as well as other large appliances.

Save and Earn

Using your usage history, weather forecasts and utility price estimates, Powerwall optimizes your stored energy to power your home more efficiently, day and night. With some utilities, you can earn money by selling your energy to the grid.

Storms - Outages

Ensure your home and appliances remain powered during an outage. When severe weather is predicted, Storm will automatically charge your Powerwall to its full capacity in preparation. In the event of an outage, Powerwall will maintain your solar system's operation or, if you're relying on grid power, will switch your home to stored energy immediately.

Maximum Efficiency, Lower Cost

The Powerwall can supply energy to your entire home with just one unit, making whole-home backup protection more cost-effective. Each unit comes with a built-in solar inverter, enhancing efficiency by reducing the number of parts and streamlining installation. This makes multi-unit systems budget-friendly and simplifies future system expansions.
