Scope of power decrease (CL12/2410LI-D):
12V: If the voltage of battery is less than 12.5V, the controller begins drop power automatically. When the voltage of battery is from 12.5V to 11.8V, the output current of the controller changes linearly from 70%~30% of the setting value. (24V: double the voltage)

CL series are intergrated with LED driver. That means the LED light needn’ t include driver, so the cost of driver is saved. CL series have the function of output current adjustable, and this function realize the load’ s power adjustable. For example, a 30W LED lights can work as follows:
The first time period: 300minutes(5hours) 30W
The second time period: 300minutes(5hours) 10W
The third time period: 180minutes(3hours) 20W
If you use ordinary solar controller, the 30W LED lights will work as follows:
The first time period: 300minutes(5hours) 30W
The second time period: 300minutes(5hours) 30W
The third time period: 180minutes(3hours) 30W
Thus our CL series help save 130Wh.

Suppose the 30W LED lights works 13 hours a day. The sun time per day is 4 days. The rainy days are 7 days. Let’ s compare the configuration bewteen these two solar light system.
