System principle: The working principle of the system is simple. The solar cell made by the photovoltaic effect principle receives solar radiation energy during the day and converts it into electrical energy for output. It is stored in the battery through the charge and discharge controller, and the illumination gradually decreases to 10lux at night. Left and right, the open-circuit voltage of the solar panel is about 4.5V, the charge and discharge controller detects this voltage and acts, and the battery discharges the lamp head. After the battery has been discharged for 8 hours, the charge and discharge controller will act and the battery will be discharged. The main function of the charge and discharge controller is to protect the battery.

  The Sun can generate system:

  working principle:

During the daytime, under the condition of illumination, the solar cell components generate a certain electromotive force, and the solar cell square array is formed through the series and parallel connection of the components, so that the square array voltage meets the requirements of the system input voltage. Then, the battery is charged through the charge and discharge controller, and the electric energy converted from the light energy is stored. At night, the battery pack provides input power for the inverter, and through the function of the inverter, the DC power is converted into AC power, which is sent to the power distribution cabinet, and the power is supplied by the switching function of the power distribution cabinet. The discharge of the battery pack is controlled by the controller to ensure the normal use of the battery. The photovoltaic power station system should also have limited load protection and lightning protection devices to protect the system equipment from overload operation and avoid lightning strikes, and maintain the safe use of system equipment.
