Brunton Solar Controller Battery Charge Monitor

Brunton Solar Controller Battery Charge Monitor One Color One Size. The Brunton Solar Controller Battery Charge Monitor prevents your 10-watt or larger solar panels from overcharging your 12-volt battery. Even the best solar panel in the world loses its luster when it overcharges your car battery into a steaming pool of acid and battery scuzz on the driveway. If your model of Brunton's solar panel doesn't have built-in overcharge protection, or you just want the peace of mind a battery charge monitor offers, then you'll appreciate the Solar Controller. This unit can handle up to 100 watts of electricity.
