The choice of Solar Studs controller is often overlooked by engineers. The quality of the controller varies. The market price of the 12V/10A controller ranges from 60 to 200 yuan, although it is the least valuable in the entire street light system. part, but it is a very important part.
The quality of the controller directly affects the component life of the Solar Studs system and the procurement cost of the entire system.
- The Solar Studs controller with lower power consumption should be selected. The controller works continuously for 24 hours. 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 below 1 mA (MA). device.
- To choose the Solar Studs 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 .
- The Solar Studs controller with multi-channel power regulation should be selected. The controller with power regulation has been widely promoted. It can automatically turn off one or two lights at night when there are few pedestrians, saving electricity, and can also target LED Solar Studs. Make power adjustments. In addition to selecting the above power-saving functions, you should also pay attention to the protection function of the Solar Studs controller for the battery and other components. For example, the Solar Studs controller with trickle charging mode can protect the battery well and increase the life of the battery. In addition, setting the Solar Studs controller When the under-voltage protection value of the Studs controller is used, try to adjust the under-voltage protection value to ≥11.1V to prevent the battery from being over-discharged.
