Household energy storage systems are composed of batteries, inverters, and control equipment that capture and control the flow of electrical energy in the home to be stored for later use. They can store grid-sourced electricity available during off-peak hours, as well as power generated by solar panels and other renewable sources. This system enables homeowners to cash in on expenses by providing stored energy during outages, at night, or during peak demand hours, thereby reducing dependency on the grid. Together with intelligent controls, the system improves energy distribution to the home for enhanced efficiency and sustainability.
