Thank you for selecting this solar charge controller. This solar charge controller is an advanced solar charger with maximum power point tracking. Applying intelligent MPPT algorithm, it allows solar charge controller to extract maximum power from solar arrays by finding the maximum power point of the array.

The MPPT battery charging process has been optimized for long battery life and improved system performance. Self diagnostics and electronic error protections prevent damage when installation errors or system faults occur. This charger also features multifunctional LCD with communication ports for remote battery temperature and voltage measurement.


• Intelligent Maximum Power Point Tracking technology increases efficiency 25%~30%
• Compatible for PV systems in 12V, 24V or 48V
• Three-stage charging optimizes battery performance
• Maximum charging current up to 60A
• Maximum efficiency up to 98%
• Battery temperature sensor (BTS) automatically provides temperature compensation
• Automatic battery voltage detection
• Support wide range of lead-acid batteries including wet, AGM and gel batteries
• Integrated intelligent slot compatible with SNMP/MODBUS communication
