The working principle of solar street lights

Explanation of the working principle of solar street lights: During the day, solar street lights are controlled by intelligent controllers. The solar panels absorb solar light and convert it into electrical energy through the irradiation of sunlight. During the day, the solar cell modules charge the battery pack, and at night, the battery pack provides power to the LED light source, achieving lighting function.

The DC controller can ensure that the battery pack is not damaged due to overcharging or overdischarging, and also has functions such as light control, time control, temperature compensation, lightning protection, and reverse polarity protection.
