Solar power generationLighting system (single lamp control) has been gradually applied in some projects and occasions, such as street lamps, courtyard lamps, lawn lamps, etc., and the development and application of this system has played a positive role in energy saving and environmental protection.

Solar energyHow solar power and lighting system works

The working principle of the centralized controllable solar power generation and lighting system: When exposed to sunlight, thesolar photovoltaiccell componentsgenerate electricity, which is then channeled through the system controller and abateryovercharge protection control port to charge the battery pack.Inverter, the utility grid interactive switch, the utility grid, and the utility switch are parts of the system that connect to the utility grid. In special cases where sunlight is insufficient or the battery pack's power supply is inadequate, the utility grid directly charges the battery pack. At the same time, if the battery pack has excess power, it is also designed to supply power to the utility grid, although this method of power supply has not been implemented yet.

The port of the lamp group connection control is adopted with a common single-chip microcomputer or other devices with computing and control functions. The electric energy of the battery group output port is transmitted through the port of the anti-overdischarge, overloading and short circuit controller, the port of the system controller lamp group connection control and the port of the constant voltage and constant current light source control, and the energy is supplied to the energy-saving light source, so that the energy-saving light source can change the brightness and color according to the actual needs.

The basic function of the solar power generation lighting system

The whole centralized controllable solar power generation and lighting system has the following basic functions:

1、Battery anti-overcharge, anti-reverse charge;

2、Battery anti-overdischarge, anti-reverse discharge;

3、Prevention of short circuit and reverse connection of the battery;

4、Provide load function;

5、Provide the user/operator with the system operating condition;

6、Control the change time of lighting changes, color changes, brightness changes, etc.);

7、Provide the function of controlling interface backup and connecting control port;

8、The entire system's surplus electricity can be provided to auxiliary loads for consumption;

9、connection with the city power grid;

10、Lightning protection grounding protection function;

11、The control function of the system can be increased or decreased according to the actual lighting needs of the customer;

12、Control the self-consumption current to be less than 1% of the rated working current;

13、The control circuit voltage drop is less than 5% of the system voltage.
