BPD Series Solar Pump Inverter

BPD series solar water-pump inverter adopts the dynamic VI MPPT technology and motor control technology, and is suitable for AC water pumps with prompt response, high efficiency and stable performance.


  • Support direct driving for single-phase motor (don’t tear down Start Capacitor), also support the three-phase 220V motor.
  •  One pump inverter can equip with mutiple motors, support vector control.
  • Protection class IP65 and fanless system design, apply quick connection terminals, with convenient installation, and meet various harsh outdoor environment.
  •  Has a bypass function, can support 220V Utility Power input and diesel engine input; optional water level detection module and diesel engine start/stop module.
  • Low start voltage and wide input voltage range give more possibilities for accepting multi PV strings configuration and different type of PV module.
  •  Digital intelligent control can Flexible adjusting and setting pump’s speed range. In addition to soft start function also can provide lightning protection, overvoltage, over current, overload protection function etc.
