Power Your Home, Save Money

Powerwall is a compact home battery that stores energy generated by solar inverter 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.

Storms Happen—Outages Don’t Have To

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.

Capture More Solar

With a fully integrated solar inverter, Powerwall can efficiently store solar energy and convert it into electricity to power your home. This means you can capture more of the solar energy your system is already generating during the day and use energy to power your home for free at night.

Avoid Peak Pricing

Savings mode optimizes your stored energy. With variable rate plans, you can program Powerwall to use your stored energy when prices spike, saving money over time.

Earn by Selling

Where grid support programs are available, you can send energy to the grid when demand is high or outages are likely. This supports the sustainable operation of the grid and may earn you credits for the energy you sell. Learn More

Maximum Efficiency, Lower Cost

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 a home battery system that can be charged from solar panels or the grid and is designed to withstand extreme weather conditions and harsh environments with minimal service or maintenance. 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.
