Powerwall
Whole-Home Backup, 24/7
Whole-Home Backup, 24/7

Powerwall is a compact home battery that stores energy generated by solar or from the grid. You can use this 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.

Keep your home and all appliances powered during an outage. When severe weather is forecast, Storm Watch will automatically charge Powerwall to its maximum capacity to prepare for an outage. When an outage occurs, Powerwall will help keep your solar system running or, if using grid power, will transition your home to stored energy instantly.

Powerwall can power your entire home with one unit, making whole-home backup protection more affordable. Each unit is self-contained with an integrated solar inverter for added efficiency, resulting in fewer parts and faster installation. This helps make multi-unit systems more affordable and system expansions easier in the future.

Backup protection only works when your backup system is reliable. Powerwall is designed to withstand extreme weather conditions and harsh environments. It can maintain normal operation in cold temperatures, high humidity and flooding in two feet of water. With Heat Mode, Powerwall heats itself intelligently to maintain optimal charge and discharge performance in temperatures as low as -4°F. View Heat Mode White Paper

Powerwall backup protection extends beyond the home. You can optimize your stored energy to charge your electric vehicle with clean energy during the day, at night or during an outage. Adjust your system settings to charge exclusively with excess solar energy, or share your electric vehicle’s battery power with your home using Powershare to extend your home’s backup support during an outage.
