A self-powered home combines solar energy and Powerwall to independently power your home day and night. During the day, solar panels may produce more energy than your home uses. Powerwall stores that excess solar energy and makes it available on demand, even after the sun has set. Through the Tesla app, you will have full visibility into your self-powered home.
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.
