Pulse Width Modulation (PWM)
PWM controllers regulate the charge flow by rapidly turning the power on and off to maintain a constant voltage. As the battery gets closer to being fully charged, the controller reduces the amount of power it sends to the battery to prevent overcharging. PWM controllers are generally less expensive than MPPT controllers but are less efficient, especially in low-light conditions.
