Selection of solar street lights and key points of later use

1: The controller with lower power consumption should be selected. The controller works 24 hours a day. If its own power consumption is large, it will consume part of the power. It is best to choose a controller with a power consumption of less than 5 mA. Two: To choose a controller with high charging efficiency, the controller with MCT charging mode can automatically track the maximum current of the battery panel, especially in winter or periods of insufficient light, the MCT charging mode is about 20% more efficient than others. 3. A controller with adjustable power should be selected. The controller with power adjustment has been widely promoted. It can automatically reduce the working current of the LED lights at night when there are few pedestrians, save electricity, and also save the configuration ratio of the battery panel. . In addition to selecting the above power-saving functions, you should also pay attention to the protection function of the controller for components such as batteries. For example, the controller with trickle charging mode can protect the battery well and increase the life of the battery. In addition, set the controller undervoltage protection. When the value is lower than or equal to 11.1V, try to adjust the undervoltage protection value to ≥11.1V to prevent the battery from being over-discharged, which will reduce the service life of the battery. Four: In places far away from the urban area, attention should also be paid to anti-theft work. Many engineering companies have not carried out effective anti-theft due to negligence in construction, resulting in the theft of batteries, panels and other components, which not only affects normal lighting, but also causes unnecessary property loss. At present, most of the stolen batteries and battery panels in engineering cases are buried in the ground and poured with cement, which is an effective anti-theft measure and can play a role in maintaining a constant temperature. If the battery box is installed on the light pole, it is best to weld and strengthen it. In addition, if the battery is far away from the controller, it must be equipped with a temperature sensing line, otherwise the controller cannot detect the temperature of the battery and cannot provide relevant temperature compensation. The theft of the battery panel is mainly due to the low pole or the clinging objects around the pole, so the height of the pole is preferably designed to be more than 5M. 5: The waterproofing of the controller, most of the controllers are installed in the lampshade and battery box, and generally will not enter the water, but in actual engineering cases, some of the controllers have not been properly installed or the circuit boards of some controllers have not been treated with three-proof paint. It will cause a short circuit because rainwater flows into the controller along the external wiring of the controller terminals. Therefore, during construction, attention should be paid to bending the internal connecting wires of the controller terminals into a U-shape and fixing them, and the connecting wires exposed to the outside are also fixed to a U-shape, so that the rainwater cannot penetrate into the controller and cause a short circuit of the controller. Apply waterproof glue to the cable interface to waterproof. Six: In the practical application of many solar street lights, the solar street lights in many places cannot meet the normal lighting needs, especially in the continuous rainy days and the lack of light in winter. In addition to the use of related components of poor quality, another main The reason is to blindly reduce the cost of components, not design and configure according to requirements, and reduce the use standards of battery panels and batteries, so the street lamps cannot provide lighting on rainy days. CHZ Changhui Lighting Technology Co., Ltd. is the largest street light manufacturer in northwest Shandong and a leading enterprise in the LED street light industry. The company is committed to providing customers with new lighting solutions and high-quality services. Years of experience in Ru0026D and manufacturing of solar street lights, with a number of national technology patents for street lights, solar street lights, LED street lights, lighting products, etc. The company has strong technical force, advanced production equipment, scientific and standardized management, and high-quality workforce. .
