PWM 30A Solar Power Charge Controller / Voltage Regulator

The solar controller regulates the voltage coming in from the solar panels and out to the battery. This will protect your battery bank from overcharging. This charge controller is 3-stage pulse width modulated (PWM). PWM is a complex method of battery charging that will maintain the battery bank at its highest state of charge at all times. PWM charge controllers pulse on and off thousands of times per second. The "off" pulse goes a little longer as the battery voltage rises. Equipped with dual USB outputs for charging phones and other small devices.
