How to adjust the time of solar street lamp controller?

The lighting time of led solar street lights is very intelligent, controlled by the strength of the sun (artificial cannot be controlled), usually 7-8 o 'clock in summer, and 5-6 o 'clock in winter. There are generally three kinds of control methods for the off time of led solar street lights.

1. Light control, light control refers to the control of light only, after installation, there is no need to adjust the lighting time according to the season, automatically off during the day and automatically on at night. This kind of light control control is now widely used in lithium-ion solar street lights, and the cost is slightly higher than several other control methods.

2. Time control, time control off the lamp is the common control method of solar street lights, that is, to set the controller in advance, the light is automatically lit at night, and the light is automatically turned off after the light reaches the specified time, this control method is relatively reasonable. It can control the cost of solar street lights and extend the service life of solar street lights.

3. Remote control, can be controlled by remote control are generally family solar street lights, in the family people hope that solar street lights can be like mains street lights, through the switch control lamps, so solar street lights manufacturers specifically for the family with solar street lights developed a controller at any time to control the lights and lights out of the family solar street lights.

At present, the most used solar street lamp control method on the market is light control + time control + temperature control.

Solar street light controller selection:

1, should choose a controller with low power consumption, the controller works 24 hours without interruption, such as its own power consumption is large, it will consume part of the power, it is best to choose a controller with power consumption below 1 ma.

2, to choose a controller with high charging efficiency, the controller with MCT charging mode can automatically track the maximum current of the panel, especially in winter or the period of insufficient light, MCT charging mode is about 20% higher than other efficiency.

3, should choose a controller with two ways to adjust the power, the controller with power regulation has been widely promoted, in the night pedestrian sparse time can automatically turn off one or two lights, save electricity, but also for LED lights power regulation.

In addition to choosing the above power-saving functions, we should also pay attention to the protection function of the controller for the battery and other components, such as the controller with trickle charging mode can protect the battery well and increase the life of the battery. In addition, when setting the undervoltage protection value of the controller, try to adjust the undervoltage protection value to ≥ 11.1V to prevent overdischarge of the battery.
