PWM solar charge controllers
PWM regulators are the most used in autonomous photovoltaic installations. They improve battery charging. To complete the full recharge, they separate the current supplied by the panels and send it to the batteries in the form of pulses. These pulses are modulated (+or- long, +or- frequent) by the precise reading of the regulator at the battery terminals. This allows it to know its charge level.
The role of PWM regulators is not only limited to the complete recharge of the battery, they also make it possible to limit the sulphation of the battery plates thanks to high frequency pulses. There are several types of PWM regulators, some have basic functions and others are more complex, are equipped with software that constantly manages the state of the battery
