MPPT Solar Charge Controller

PC1800A Series MPPT Solar Charge Controller (30/40A)

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.


  • Intelligent Maximum Power Point Tracking technology increases efficiency 25%~30%
  • Compatible for PV systems in 12V,or24V
  • Three-stage charging optizes battery performance
  • Maximum charging current up to 30A/40A
  • Advanced MPPT technology,with efficienQf no less than 99%
  • Maximum DC- DC conversion efficiency of 98%
  • Battery temperature sensor(BTS) automatically provides temperature compensation Automatic battery voltage detection
  • Integrated intelligent slot compatible with 485 communication
