A solar charge controller, also known as a solar regulator, is a device used in solar energy systems to regulate and control the charging of batteries from solar panels. Its primary function is to prevent overcharging or overdischarging of the batteries, ensuring optimal charging and extending their lifespan. Here are some key points about solar charge controllers:
Charging regulation: Solar charge controllers monitor the voltage and current from the solar panels and regulate the charging process to ensure the batteries receive the appropriate amount of charge. They prevent overcharging by reducing or stopping the charging current when the battery reaches its maximum voltage level.
