Meet Powerwall, your home battery.
Tesla Powerwall is a fully-integrated AC battery system for residential or light commercial use. Its rechargeable lithium-ion battery pack provides energy storage for solar self-consumption, time-based control, and backup.
With solar and Powerwall, solar energy will continue to power your home and recharge Powerwall. Without Powerwall, solar will shut down during an outage.
Powerwall can detect an outage, disconnect from the grid, and automatically restore power to your home in a fraction of a second. You will not even notice that the power went out. Your lights and appliances will continue to run without interruption.
