Benwei Solar analyzes how to choose a solar street light controller for you
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. Choose a controller with a power consumption of less than 1 mA.
2. To choose a controller with high charging efficiency, the controller with MCT charging mode can automatically track the large current of the battery panel, especially in winter or when the light is insufficient, the MCT charging mode is about 20% more efficient than other charging modes.
3. The controller with two channels of power regulation should be selected. The controller with power regulation has been widely promoted. One or two channels of lighting can be automatically turned off at night when pedestrians are scarce to save electricity. It can also adjust the power of LED lights. . In addition to selecting the above power-saving functions, you should also pay attention to the controller's protection function of the battery and other components. For example, the controller with trickle charging mode can protect the battery well, increase the battery life, and set the controller under-voltage protection. When the value is set, try to adjust the undervoltage protection value to ≥ 11.1V to prevent the battery from over-discharging.
