Tracer solar charge controller


Smart-MPPT series intelligent MPPT solar controller is programmable and especially for solar light system.
The charging efficiency is about 20% higher than the traditional PWM controller, which can make the cost of the whole system much lower.

  • Innovative Max Power Point Tracking (MPPT) technology, tracking efficiency> 99.9%.
  • Full digital technology, high charge conversion efficiency up to 97%.
  • Remote unit to configure with LCD display.
  • 12/24V automatic recognition.
  • IP67, strong and durable aluminum case.
  • External temp sensor, automatic temp compensation.
  • Four stages charge way: MPPT, Boost, Equal, Float.
  • Full automatic electronic protect function.
