30A PWM Solar Charge Controller 12V/24V Solar Battery Panel Controller Auto Parameter Charger Regulator 1Pcs

PWM technology is a electronics technology applied to solar panels and other power generation equipment. Its purpose is to keep these devices at the maximum power output point through program and circuit design to improve their output efficiency.The solar charge controller has a built-in maximum power tracking program, which can significantly improve the energy utilization efficiency of the photovoltaic system. The LCD display allows you to understand the status and data of the solar charge controller, making it convenient for you to switch modes and parameter configurations. The solar charge controller has over-voltage, short circuit, overload, over-charge and over discharge protection functions. The controller is 12V/24V automatic adaptation. When using the solar charge controller, connect the battery first, then connect the solar panel. When using for the first time, please make sure the battery has enough voltage so that the controller can recognize the correct battery type. When connecting the circuit, please pay attention to distinguish the positive and negative poles.
