How Powerwall Works
Store energy, use when needed, save money
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 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.
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.
Energy That's There When You Need It
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.
