How Solar + Storage Works (Exports to The Grid)
Sunnova SunSafe® automatically manages the energy flow and will be designed to help meet your home energy needs. Unlike a solar-only system, you can produce solar energy during the day during a power outage; the battery stores excess energy for use at night.* When charged at 100%, you can power your most needed lights and appliances for approximately 10-13 hours*, depending on battery(s) capacity and your usage.
See below for how the system will work during normal operation and during an outage.
During Normal Operation (Grid Is Up)
During The Day – Sunlight hits your panels producing clean, renewable energy, which is used to power your home. Any excess energy is sent to the battery or the grid. Your battery will be charged before energy is exported to the grid.
At Night – Your home will be powered by the grid, and possibly some of the energy stored in the battery depending on its configuration.
