Smart solar charge controller

SKU: 123 Category:

Smart-DC series intelligent solar controller, is programmable and especially for boost mode LED solar street light system. It includes constant current driver function, which can make the cost of the whole system much lower.

  • Can output constant current (output current can be set). Accuracy: 50mA, Min current: 30mA
  • 5 stages time and dimming can be adjusted, dimming 0~100%
  • Can read parameters and running status by remote unit: S-unit
  • 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
  • Liquid and GEL battery for selection
  • External temperature sensor
  • Four stages PWM charging: fast, boost, equalization, float
  • Day/Night threshold voltage can be adjusted automatically
  • Remote Unit to configure, with LCD display
  • IP67, Strong and durable aluminum case
  • Full automatic electronic protect function
