Solar Charge Controllers. Solar charge controllers are designed to do two primary things within a solar power system: optimize the charging of your deep cycle batteries by the solar panels and prevent electricity from the batteries from going through the solar panels when there is no sun.
Charge controller prevents overcharging of 12-volt batteries. Intended for use with 12-volt solar panels. Handles up to 7 amps of array current and up to 100 watts of solar power. Charging light indicates the battery is charging, and a green light indicates a fully charged battery.
