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.
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.
