MPPT solar street light controller (with boost constant current drive)Product overview
This controller innovatively combines the LED boost constant current driver and MPPT (maximum power point tracking) charge controller together. It can be applied to all kinds of solar LED lamps, such as solar street lamp, garden lamp, landscape lamp, advertising lamp and etc.
1. Adopts MPPT (maximum power point tracking) technology, the charging efficiency is 30% higher than the PWM.
2. 12V / 24V auto work, multi-stage intelligent dimming, accurate power adjustment, relevant parameters can be set.
3.Embedded high performance LED constant current drive power, the maximum constant current efficiency is higher than 96%.
4. Protection: with over charge, over discharge, battery anti-reverse, anti-reverse charging, overload, LED open circuit and load short circuit protection.
5. With temperature compensation, can adjust the battery charging parameters according to the environmental temperature automatically.
6.All metal case design, IP68, good heat dissipation and waterproof, can work normally under harsh environment.
7. Intelligent soft start technology, which can reduce the impact on constant current source and LED load.
8. With over temperature drop load and frequency protection function.
9. According to battery power and the recent weather conditions, can intelligently adjust the output power.
