MPPT1050-DCLiR is a sort of intelligent solar charge controller.
It is fit for 12V system voltage, 10A maximum charging current, 60W maximum load power, output voltage range 20~45V.
This street light solar charge controller adds a PIR sensor based on MPPT-DCLi, designed for lights that requiring infrared induction, combined with MPPT charging technology, to realize the best application.
Working function:
The modes of lighting can be set according to customer's detailed demand by remote control S-UNIT. You could set 5 stages work time, time 1~time 5, at the same time, dimming 0~100% is available. In addtion that, because of PIR sensor, the light could work when people come and go out when people go away. That will save energy to keep the light working longer. So it is very smart and flexible.
The MPPT solar controller works as follows:
After the arrival of the evening, at the first time, the light work for 1 hour(full power 100%), at the second time, the light work for 2 hours (power 80%), at the third time, the light work for 3 hours (when people is near the light, then the light work at power 60%, when people is away from the light, it work at power 60%*10%), and then controller according to the actual night time automatically calculate the length of the fourth paragraph (when people is near the light, then it work at power 40%, when people is away from the light, it work at power40%*10%), at the fifth time,the light work 2 hours (full power 100%).
This infrared remote controller S-UNIT could not only set data but also could read status and data of MPPT LED light solar controller. So when the light doesn't work, S-UNIT will find the fault.
