Description of Function
MPPT-DC series intelligent MPPT solar controller is programmable and
especially for boost mode LED solar street light system. It includes
constant current driver function. The charging efficiency is about 20%
higher than the traditional PWM controller, which can drop the cost of the
whole system.
Innovative Max Power Point Tracking(MPPT) technology, tracking efficiency >99.9%
Full digital technology, high charge conversion efficiency up to 97.5%, discharge
conversion efficiency up to 96.5%
Can output constant current (output current can be set)
Can read parameters and running status
If battery voltage is low, it can be set to dimming
Dimming start voltage and percentage can be set
Day/Night threshold can adjust automatically
When BMS power off because of LVD, it can activate the system automatically
External temperature sensor, automatic temperature compensation(AGM, Liquid and GEL)
Four stages charge way: MPPT, boost, equalization, float
IP67, Strong and durable aluminum caseFull automatic electronic protect function
