PWM Solar Charge Controllers

PWM Solar Charge Controllers

Traditional Pulse Width Modulated (PWM) Solar Charge Controllers force your solar panels to operate at the same voltage as your battery bank during charging. They tend to be less expensive than MPPT (Maximum Power Point Tracking) charge controllers, but they're also less efficient. See our video on the differences between PWM and MPPT Charge Controllers below.
