MPPT solar charge controller

Description

MPPT-DC series solar charge controller use the most advanced MPPT technology ,the tracking efficiency >99.9%.It makes your solar system generate maximum solar power  30% more than ordinary charge controllers. It combines solar charge controller and LED constant current driver into one unit which is ideal for solar LED street light, especially when dimming function is needed.
12V/24V system voltage automatic recognition, with waterproof IP67 protection degree enable, it operate normally under tough conditions.

  • 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 programmable)
  • 5 stages time and dimming can be adjusted, dimming 0~100%
  • Can read parameters and running status
  • If battery voltage is low, it can be set to dimming automatically
  • Dimming start voltage and dimming percentage can be set
  • 12V/24V system voltage automatic recognition
  • AGM,Liquid and GEL battery for selection
  • External temperature sensor
  • Four stages charge way: MPPT, boost, equalization, float
  • Day/Night threshold can be adjusted
  • Remote Unit to configure, with LCD display
  • IP67, Strong and durable aluminum case
  • Full automatic electronic protect function
