Solar street light controller has an irreplaceable significance and role in the road lighting system. It is the monitoring center and leading part of solar street light. Solar street light mainly works under normal conditions through it, so the choice of solar street light controller is very important. Due to the expansion of demand, there are more and more facilities related to street light control system on the market, how should we judge its quality problems?

In the process of daily use we will find that the solar street light will be affected in the continuous cloudy days or no sunny weather conditions, and will not be very bright. While the battery voltage is normal, even if there is a problem with the street light controller light source can still be normal lighting. In fact, the reason for this situation is that the voltage value cancelled in the undervoltage protection is generated again after high undervoltage, caused by the relatively slow repair speed.
Because of the characteristics of the led light source itself, it must be manipulated by constant current or limited current, otherwise it will affect its service life, by setting another drive power to achieve constant current control of led lamps. This intelligent street light controller loses a lot of power. Therefore, the constant current control function is integrated into the controller, which can effectively reduce the loss of electrical energy.
In the past, the traditional type of controller will be set to turn off the lights after four to eight hours, but there is a difference between the winter and summer lighting time, such a control method will increase the economic costs, and can not meet the needs of users. The solar street light controller can choose the time of the switch at will, to achieve independent and free to set the time period.
