  Whether the power source is solar panels, wind, hydro, gasoline, or the utility grid, a charge controller is an integral feature of practically all power systems that charge batteries. Its function is to ensure that your deep cycle batteries are adequately fed and safe over time. A controller’s basic functions are straightforward. Charge Controllers prevent battery overcharging by blocking reverse current. Some charge controllers additionally protect against battery overcharging, defend against electrical overload, and/or show battery status and power flow. How Do Charge Controllers Function? It’s important to understand that electricity flows from high to low voltage. Solar panels, for example, produce the greatest energy during the middle of the day; thus, their voltage is high while the voltage of the battery bank is low. The excess electricity is subsequently supplied to the battery to be stored. The battery, however, has a higher voltage than the solar panels at ni...
