Our common street lights include solar street lights, city circuit lights, wind street lights and wind-solar hybrid street lights. And different street lights correspond to different controllers. Solar controllers and wind power controllers are used in solar street lights and wind street lights, respectively. What are their differences and commonalities?

First of all, their main functions are roughly the same. Its main functions are:
1. Ensure the current and constant current output, so that the LED light source can work normally.
2. Protect the battery from overcharge and overdischarge to prevent frequent overcharge and overdischarge of the battery, prolong the service life of the battery, the overall configuration and budget of the solar panel, and greatly effectively prolong the life of the LED lamp.
3. Control the output period and output power of the street light, so that the street light can have different power in different time periods according to the actual demand.
Their working principle and applicable places are different.
The wind controller is mainly used in the street lamps of wind power generation. After the battery is fully charged, the controller should control the battery not to be overcharged. When the electric energy stored in the battery is discharged, the controller should control the battery not to be over-discharged to protect the battery.
Solar controllers are mainly used in street light systems that use solar energy as energy. The solar street light controller itself has two functions: time control and light control. The light control plays the role of turning on the lights in the dark and turning off the lights in the daytime.
