In the solar energy teaching experiment box, the function of the controller is to specify and control the charging and discharging conditions of the battery, and control the electric energy output of the solar cell and the battery to the load according to the load's demand for power supply. The controller is a monitoring device for automatic charging and power consumption. When the battery is fully charged, it will automatically cut off the charging circuit so that the battery will not be overcharged.
