Its strengths

  • With MPPT technology, the controller has a higher response speed and tracking efficiency, which significantly improves the efficiency of using the energy of solar panels.
  • Works with GEL (lead) and lithium battery; the operating parameters can be adjusted by remote control.
  • Temperature compensation function and multi-level constant voltage charging for lead-acid battery.
  • Control of charging power and time.
  • Protection and adjustment of the charging and discharging temperature of the battery.
  • Smart Power Mode: Charging power can be adjusted automatically based on battery level.
  • High precision digital control algorithm of elevation voltage and constant current: ensures high efficiency and high accuracy of constant current.
  • Protection against reversal of battery/PV electrodes, protection against short circuits, open circuits and limited power of LEDs, etc.
  • Infrared remote control: allows setting of parameters and checking of status.
  • With a metal outer shell and IP67 waterproof rating, the product can work properly in various difficult situations.
