12V/24V 40W solar controller with LED driver

TL12/2408LI-40W is solar controller for LED solar street light. This solar light controller is integrated with LED driver, so the led light can’t have LED driver. And this also saves the cost of Led driver. The maximum conversion efficiency reaches 96%. The product is an advanced intelligent solar charge controller.

  pcs/kgs per CTN



  12V: Solar LED light with max. 40W LED (The circuit of LED should be 3    series/8V-11V) 

  24V: Solar LED light with max. 40W LED (The circuit of LED should be 6  series/16-22V)


1.  Light controlling, time controlling and output current adjustable in 4 time intervals.

2.  Integration with LED driver. So the led light can’t have driver.

3.  Automatically recognize voltage.

4.  Under-voltage and over-voltage protection.

5.  Battery reverse polarity protection.

6.  Reverse discharging protection.

7.  Lightning protection

8.  output end protection(open circuit, short circuit, over current, over voltage, over load)

9.  over temperature protection

10. Temperature compensation to battery

11. Trickling charge protection

12. Excellent waterproof protection

13. Standing high/low temperature: our controller can work stably for a long time at the temperature from -35℃ to 60℃

14. TL12/2408LI-40W has an optional function that the controller can automatically drop load’s power when battery is lower than 12.5V/25V. This function let the lights work for longer days in rainy season.

15. Another optional function of TL12/2408LI-40W is the controller can adjust the working time automatically in different seasons. In winter, the working time becomes long, while in summer, the working time becomes short automatically.
