Photovoltaic power generation systems are usually divided into grid-connected power generation and off-grid power generation.
PWM refers to the use of the digital output of the microprocessor to control the analog circuit, and it is a method of digitally encoding the level of the analog signal.
The so-called MPPT (Maximum Power Point Tracking) is the maximum power point tracking. The maximum power point tracking controller is a device designed in the controller that can perform intelligent calculation and implement tracking at any time to realize real-time monitoring of the power generation voltage of the solar panel, and track the highest voltage and current value (VI).
The full name of MPPT controller is "Maximum Power Point Tracking" solar controller is a replacement product of previous solar charge and discharge controllers.
The mppt solar charger is a device that converts solar energy into electrical energy. The solar energy is converted into electrical energy and then stored in the battery. The battery can be used as any form of power storage device.
The solar controller is mainly used for photovoltaic modules to charge the battery. It can stabilize the voltage during the charging and discharging process and avoid device damage caused by overcharging. Therefore, the full name of the controller is also called the solar charge and discharge controller, which is divided into MPPT solar controller and PWM solar controller.
