How It Works

During daylight hours your solar panels generate electricity. Surplus energy is stored in the Fox ESS battery rather than exported to the grid. In the evening your home draws from the battery, reducing or eliminating grid electricity use. If the battery depletes, the system seamlessly switches back to the grid.
