40W MPPT solar controller with LED driver

CLM12/2408LI-40W is solar controller for LED solar street light adopting MPPT technology. The max tracking reaches 99.95%. The max conversion efficiency reaches 96%. Compared to ordinary controller, this controller can improve the conversion efficiency by 15%-20%.

Besides MPPT technology, this product also integrates solar controller and LED driver in one. This can help customers save the cost of LED diver.



1. Advanced MPPT algorithm with the max. tracking efficiency of 99.95%

2. realizing peak conversion efficiency 96%

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

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

5. Automatically recognize voltage.

6. full protection function

7. Temperature compensation to battery

8. Excellent waterproof protection

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

10. Optional function one: 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.

11. Optional function two: 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.
