Friends who know solar energy may have heard or even understood pwm solar charge controller! The pwm solar charge controller is an automatic control device used in a solar power generation system to control the multi-channel solar battery array to charge the battery and the battery to supply power to the solar inverter load. It regulates and controls the charging and discharging conditions of the battery, and controls the power output of the solar cell components and the battery to the load according to the power demand of the load. It is the core control part of the entire photovoltaic power supply system.

The basic function of the pwm solar charge controller is to control the battery voltage and open the circuit, and when the battery voltage rises to a certain level, it stops charging the battery.

Controllers are used in most photovoltaic systems to protect the battery from overcharging or overdischarging. Overcharging may vaporize the electrolyte in the battery, causing failure, while overdischarging the battery will cause premature failure of the battery, and both overcharging and overdischarging may damage the load. Therefore, the controller is one of the core components of the photovoltaic power generation system and is also a balance main part of the system.
