The solar array on your roof produces enough electricity to power your home during the day. When you don’t use all the energy your system produces, the solar panels on your roof are busy charging your battery with solar electricity to create energy storage. When the sun goes down, or in the event of a power outage, you can continually power your home with the electricity stored in your battery backup. With solar panels to charge your backup home battery, you can power your home through every outage.
