How Do Solar Battery Systems with Backup Work?

In this article we'll explain how combining a solar power system with battery backup like SunVault Storage can power your home with cleaner energy, lower your electric bills and keep the lights on when grid power goes out.

Key Features of the SunVault Storage System with Battery Backup

Charge with solar

As your SunPower Equinox system produces energy, it sends the electricity you're not using to SunVault Storage and/or sells it back to the grid for a credit on future electric bills.*

Manage peak demand usage

Intelligent software monitors your solar, home energy use and utility rates to determine which power source to use, maximizing use of solar and reducing peak-time charges.

Backup your essentials

When the power goes out, SunVault Storage can provide seamless backup to power your essential appliances, such as keeping the lights on or running your refrigerator.*
