Meet Powerwall, your home battery.
How does Powerwall work 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. If you have solar and Powerwall, then solar energy will continue to power your home and recharge Powerwall. Without Powerwall, solar will shut down during an outage.
Seamless backup power. With or without solar.
Powerwall detects grid outages and automatically becomes your home’s main energy source. Protect your home from the next power outage and keep your lights on, phones charged, and no puddles under the fridge.
Self-Powered home. Just add Powerwall.
Powerwall integrates with solar to store excess energy generated during the day and makes it available when you need it, minimizing reliance on your utility.
Compact and Simple
Powerwall is a completely automated system that installs easily and requires no maintenance.
