Solar street light controller, understand nature is not too much, any street light will be equipped with a special controller, next we explain in detail how to choose the solar street light controller.
One: should choose a controller with low power consumption, the controller works 24 hours without interruption, such as its own power consumption is large, it will consume part of the power, it is best to choose a controller with power consumption below 3 ma.
Two: To choose a controller with high charging efficiency, a controller with a three-stage charging control mode of strong charging, balanced charging, and floating charging, MCU intelligent control is used, and through internal calculation, the battery can always be charged with maximum power, especially in winter or the period of insufficient light. Charging mode with MCU intelligent control is about 20% more efficient than non-MCU intelligent controller.
Three: with high-precision control, high-precision is the comprehensive embodiment of product design, but also the embodiment of excellent material selection, but also the embodiment of the production process. Non-high-precision control of the solar street lamp controller is often due to unreasonable product design, poor material selection, etc., resulting in high repair rate, poor reliability, and low market price.
Four: Only a controller with two separate controls is selected, so that it is convenient for the power regulation of solar street lights. In the night when pedestrians are scarce, one or two lights can be automatically turned off, saving electricity, and power adjustment can also be made for LED lights. In addition to the above power-saving functions, when setting the controller undervoltage protection value, set the undervoltage protection value to ≥10.8V to prevent battery overdischarge.
