Keep the Lights Shining Bright

Now available with SunPower Equinox® rooftop solar system, the Tesla Powerwall 3 is an affordable home backup solution offering uninterrupted power and better battery performance, so yours can be the house on the block where the lights shine bright and electricity bills drop.*


Charge with Solar

As your SunPower Equinox® system generates energy during the day, any energy you're not using is sent to your solar battery system for later use. Depending on the storage system you choose, this stored electricity can be used to help you save on your electricity bills or power your home during an outage. *
