The benefits

  • With MPPT technology, the controller has higher response speed and tracking efficiency, significantly improving the efficiency of solar panel energy use.
  • Works with both GEL (lead-acid) and lithium batteries; operating parameters can be set by remote control.
  • Temperature compensation function and multi-level constant-voltage charging for lead-acid batteries.
  • Control of charging power and time.
  • Protection and adjustment of battery charging and discharging temperature.
  • Intelligent power mode:
  • Charging power can be automatically adjusted according to battery level.
  • High-precision digital control algorithm for boost voltage and constant current: ensures high efficiency and constant current accuracy.
  • Protection against reversal of battery/PV electrodes, protection against short circuits, open circuits and limited LED power, etc.
  • Infrared remote control: enables parameter setting and status checking.
  • With a metal outer shell and IP67 waterproof rating, the product can operate properly in a variety of challenging situations.
