Operation mechanism of solar power system

During the day, the solar cell modules generate a certain electromotive force under light conditions, and the solar cell array voltage can meet the system input voltage requirements through the series and parallel connection of the modules. Use the charge and discharge controller to charge the battery again, and convert the light energy into electrical energy for storage. At night, the battery pack provides input power for the inverter. Through the function of the inverter, the DC power is converted into AC power, and the power is supplied to the power distribution cabinet through the switching action. The controller controls the discharge of the battery pack to ensure the normal use of the battery. The PV system should also have a certain load protection and lightning protection device to protect the overload operation of the system equipment and prevent lightning strikes, and maintain the safe use of the system equipment.
