The photovoltaic system consists of the following three parts: solar panels, solar controllers, inverters, test instruments and computer monitoring and other
The most basic function of the solar charge and discharge controller is to control the battery voltage and turn on the circuit, and when the battery voltage rises to a certain level, stop the battery charging.
To charge the battery, the output voltage of the solar panel must be higher than the current voltage of the battery, if the voltage of the solar panel is lower than the voltage of the battery,
The mppt regulator refers to the main command device that changes the wiring of the main circuit or the regulating circuit and changes the resistance value in the circuit according to a predetermined order to control the starting, speed regulation, braking and reverse direction of the motor.
