  • Maximum PV short-circuit current: 50A
  • Battery voltage range: 9V–35V; maximum battery voltage: 32V
  • MPPT tracking efficiency: greater than 99%; conversion efficiency: up to 98%
  • Protection rating: IP32
  • Operating dimensions: 9.37 × 6.81 × 2.85 inches; net weight: 4.41 lb

Safety Features and Certifications

  • Electronic protection against reverse polarity, overcharging, overload, short circuit, and reverse current
  • Lithium battery recovery function for over-discharged lithium batteries
  • Die-cast aluminum housing supports heat dissipation
  • IP32 enclosure rating

Installation and Maintenance Requirements

Install in a compatible 12V or 24V solar battery system. The maximum terminal size is 8 AWG. Confirm PV voltage, battery voltage, and polarity during commissioning; the controller automatically detects nominal system voltage. Provide sufficient clearance around the 9.37 × 6.81 × 2.85-inch enclosure for ventilation and service access. The LCD and LED indicators display charging status, battery information, operating parameters, and fault codes.
