How to Choose the Controller of the Solar LED Street Light

The main controlling sector of the solar LED street light is the controller, which is the “central nervous” of the solar street light, and it controls the charge, discharge, and overcharge protection of the capacitor, and also the protection of the whole system of the solar street light. However, how to choose the controller of the solar street light?

Solar LED Street Light

1.  Choose the controller with high charge efficient. The controller with the MCT charge mode can track the maximum electric current of the solar panel automatically, especially in winter or in the period lack of sunshine, the charge efficient of MCT charge mode can be 20% higher than others.
2. Choose the controller with low consumption. The controller works continuously for 24 hours, and it will consume more electrical energy if it consumes more. It will be better to choose the controller whose consumption is under 1mA.
3. Choose the controller with duplex power regulating. The controller with the function of power regulating is widely applied, and one-way or two-way illumination can be turned off if there are less people at night, which can save energy and regulate the power of LED. Except for the function of energy-saving, the battery protection function of the controller should be paid more attention, and the controller with trickle charge mode can protect the battery and enlarge the service time of battery. In addition, set the under voltage protection value under 11.1 V to protect over discharge of the battery.

Those should be considered in choosing the controller of solar street light, but the details should be discussed with the technicians. For if the wrong controller is used, it not only hinder the normal work of solar street light, but may cause damage of the parts of the street light.
