Solar controller charger street lamp

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
