Features
1、Protect the current constant current output
As the LED itself needs to be constant current or current limit by technical means, otherwise it simply can not work properly. The general approach used in LED lights is usually an additional drive power supply to carry out the LED constant current, but this needs to bring power loss, making plus the independent drive power supply more power consumption, so this approach is less desirable.
2, control the output time
A solar controller can set a good time period, to set a good time period to start the output current to start working.
3, the output power adjustment
In the application of solar street lights, the power is adjusted. Adjusting the power can control the brightness of LED lights, such as street lights in the early morning to adjust to 30W, late at night to adjust to 15W energy saving, so that the current is locked to meet both the lighting needs at night, but also to save the battery, solar panels, the overall configuration, and budget, but also can greatly and effectively extend the life of LED lights.
Select
1.: You should choose a controller with low power consumption, the controller works 24 hours a day, such as its own power consumption, it will consume part of the electricity, it is best to choose a controller with a power consumption of less than 1 mA.
2: should choose a controller with high charging efficiency, with MCT charging mode controller can automatically track the maximum current of the battery panel, especially in winter or the period of insufficient light, MCT charging mode is about 20% more efficient than others.
3: should choose a controller with two-way power regulation, with power regulation controller, has been widely promoted, at night when pedestrians are scarce time can automatically turn off one or two-way lighting, saving electricity, but also for LED lights for power regulation. In addition to choosing the above power-saving features, should also focus on the controller to the battery and other components of the protection function, like a controller with trickle charge mode can be a good protection of the battery, increase the life of the battery, in addition, to set the controller under-voltage protection value, try to under-voltage protection value in ≥ 11.1V, to prevent the battery over-discharge.
