Solar Charge Controller: A solar charge controller, also known as a solar regulator or solar panel controller, is a critical component in a solar photovoltaic (PV) system. Its primary function is to regulate and manage the power flowing from solar panels to the battery bank. A solar charge controller ensures that the battery bank receives the optimal amount of charge from the solar panels while preventing overcharging and damage to the batteries.

Maximum Power Point Tracking (MPPT): MPPT is an advanced technology used in certain types of solar charge controllers. It allows the charge controller to track and find the “maximum power point” of the solar panel’s voltage-current curve. By continuously adjusting the operating voltage and current, an MPPT charge controller can extract the maximum available power from the solar panels under varying weather conditions and solar irradiance levels.
