The working principle and basic functions of solar power lighting system

Working principle of solar power lighting system

The working principle of the centralized controllable solar power generation lighting system: under the irradiation of sunlight, the electric energy generated by the solar photovoltaic cell components is charged to the battery pack through the system controller and the battery overcharge prevention control port. Inverter, mains grid-connected switch, mains grid and mains switch are the connection parts of the system and the mains grid. In the special case of insufficient sunlight or insufficient battery power supply, the city grid directly charges the battery. At the same time, the battery has surplus power, and the design can also supply power to the city grid. This power supply method has not yet been implemented.

The light group connection control port adopts the common single-chip microcomputer or uses other devices with arithmetic control function. The power of the output port of the battery group is connected to the energy-saving light source through the anti-over-discharge, overload, short-circuit controller port, through the system controller lamp group connection control port and the constant voltage and constant current light source control port, and the energy-saving light source can be changed according to actual needs. Brightness and color.
