1. First of all, you should try to choose a controller with lower energy consumption. The controller needs to work uninterrupted for 24 hours. If its own consumption function is large, it will consume a part of the electric energy. Choose the best power consumption under 1 mA Street light controller.
2. Secondly, we must choose a high-efficiency charging controller, especially in winter or seasons when the light is not enough, the charging mode is about 30% higher than the general efficiency.
3. In addition, you should choose a controller with more than one channel and a power adjustment function. Now the controller with power adjustment function has been promoted multiple times, especially in the darker period when pedestrians are scarce, can save electricity.
