1. UNDERSTANDING SOLAR CONTROLLERS

Solar controllers, also known as charge controllers or regulators, play an indispensable role in photovoltaic systems. They regulate the voltage and current coming from the solar panels to the batteries or electrical devices. Without a charge controller, solar panels could potentially overcharge batteries, leading the batteries to degrade faster than expected or even causing them to fail prematurely.
