Brunton Solar Controller 12 Volt Charge ControllerDescription: The Brunton Solar Controller 12v Battery Charging Monitor is an helpful tool to help you avoid overcharging your 12-volt batteries. The manufacturer says that once connected you can charge your 12v battery nonstop for days. The controller will cut off the power when charging is complete.  It’s also good for maintaining the battery in its fully charged state (i.e. RV parked for days or boats). It’s compatible with most of the solar panels (of different brands too) available.

Now You Can Avoid Battery Frying and Control its Charge

Solar charge controllers help in protecting batteries from overcharge and excessive discharge. The controller assures that the battery is charged fully and keeps it that way without causing damage to the battery.

A basic solar charge controller will monitor the battery voltage, open the circuit and then stop charging when the voltage rises to a given level.

Pulse Width Modulation (PWM)

The modern solar charge controllers use pulse width modulation (PWM) which gradually lowers the amount of power as the batteries get closer to being fully charged.

The battery is charged with lesser stress thus prolonging the battery life. PWM has no mechanical connections that need to be broken although it’s quite complex.
