Solar panels convert sunlight into direct current electricity (DC).
Your inverter tells energy where to flow and converts it into alternating current electricity (AC), so it can be used in your home.
Your electrical panel distributes AC electricity to your entire home. You probably know it by its other name, "Fuse Box."
The meter tracks how much power you are pulling from and putting back into the utility’s grid. When you are putting power back into the grid, the meter will run backwards.
The battery serves 3 main functions
