The full Flex P³ system can detect an outage, disconnect from the grid, and automatically restore power to your home in a fraction of a second. You will not even notice that the power went out. Your lights and appliances will continue to run without interruption. If you have solar and Flex P³, then solar energy will continue to power your home and recharge Flex P³. Without Flex P³, solar will shut down during an outage. We estimate how long your home will stay powered during an outage based on your indicated home size and the appliances you elect to back up, derived from national data. With solar, your Flex P³ charge will deplete only when your home energy usage exceeds your solar power production. We cap our estimate at 7 days to account for the occasional cloudy day that may impact solar production.
