A PWM Solar Charge Controller: How They Work, Pros & Cons

As solar panels produce energy from sunlight, the PWM solar charge controller acts as the brains of the system by: Converting the higher DC voltage from solar panels to the correct charging voltage for your batteries. Most 12V panels put out 16-20V, so the controller brings it down to 14-15V for 12V batteries.

Which solar charge controller: PWM or MPPT?

The PWM controller is a switch which connects the solar panel to the battery. When the switch is closed, the panel and the battery will be at nearly the same voltage. Assuming a discharged battery the initial charge voltage will be around 13 V, and assuming a voltage loss of 0.5 V over the cabling plus controller, the panel will be at Vpwm = 13 ...

MPPT vs PWM: Comprehensive Guide to Solar Charge Controllers

MPPT is more advanced and efficient as it adjusts its input to harvest the maximum power from the solar array, where PWM operates at a lower efficiency and simply prevents the battery from being overcharged by limiting the amount of power going from the solar panel array to the battery. Let me draw you a picture: imagine you''re a hare (battery).
