A solar charge controller (also known as a regulator) is identical to a traditional battery charger. Its function is to manage the solar charging process to ensure that the battery is effectively filled or, more critically, not overloaded. While solar charge controllers come in a wide variety of budgets, supply voltage, and functionalities, there are two major types: PWM and MPPT solar charge controller units. PWM variants are less complicated, utilizing a switch between the solar plant system and the storage devices. We will dive deeper into the difference later in this article.
Various battery kinds are supported, much like with any standard battery charger. Normally, the absorption and float voltages are selectable. In addition…
