Shanghai Qingpu Huitong equipment case

　　In the daytime, the solar cell component generates a certain electromotive force under the illumination condition, and the solar cell square is formed by the series and parallel connection of the components, so that the voltage of the square matrix meets the requirement of the input voltage of the system. The battery is charged by charging and discharging controller, and the energy stored by light energy conversion is stored. In the evening, the storage battery provides the input power for the inverter. Through the function of the inverter, the DC power is converted into alternating current to the power distribution cabinet, and the power supply is supplied by the switching function of the distribution cabinet. The discharge of the storage battery is controlled by the controller to ensure the normal use of the battery. Photovoltaic power plant system should also be limited load protection and lightning protection devices, in order to protect the system equipment overload operation, and from lightning strike, maintain the safe use of system equipment.
