Description

A solar charge controller is a vital component in a solar power system that regulates the power going from solar panels to batteries, preventing overcharging and extending battery life. It acts as a middleman, managing the voltage and current coming from the solar panels to ensure the batteries are safely charged and are not damaged due to excessive or insufficient charge. Solar charge controllers typically come in two main types: PWM (Pulse Width Modulation) and MPPT (Maximum Power Point Tracking). While PWM controllers are simpler and less expensive, MPPT controllers are more efficient, especially for larger systems, as they adjust to the optimal power output of the solar panels in real time.
