PWM CHARGE CONTROLLERS


Traditional solar regulators featuring PWM charging (pulse width modulation), operate by connecting the solar array directly to the battery bank. When the array is connected directly to the battery bank, the array output voltage is ‘pulled down’ to the battery voltage. This occurs because the batteries are a very large load for the limited current sourcing capability of a solar array.
