PWM controller is unable to capture excess voltage because the pulse width modulation technology charges at the same voltage as the battery. However, when solar panels are deployed in warm or hot climates, their Vmp decreases, and the peak power point operates at a voltage that is closer to the voltage of a 12V battery.
Our solar charge controllers are powered by latest generation microprocessor and PWM Technology. It makes your solar system generate maximum solar power 30% more than ordinary charge controllers. The microprocessor enabled six stage charging ensures optimum charging of batteries which increases their life by 6 months.
