Solar Water Pump Inverter

PT100 Series (1.5-55KW)

PT100 series is MUST newly launches specially for solar pumping inverter applications. Based on the original solar pump inverter products, which optimizes the usability and performance, and extends applicable voltage levels and power range of the product. The voltage level can be applied to single phase/three phase 220V, three phase 380V pumps, power range from 1.5KW to 55KW.


  • Support single phase/three phase 220V, and three phase 380V solar water pump inverter, power from 1.5KW to 55KW
  • Simply connect the photovoltaic panel to the solar water pump inverter, and the PV pump can be automatically started after power-on
  • It has protection functions such as PV over-voltage protection, over-temperature automatic protect, etc., which can effectively extend
    the life of the product
  • Ensure solar power tracking efficiency can reach 99%
  • All series of products can realize automatic switching of PV DC input and grid AC input, which can meet 24 hours of no care work
  • Supports IP20 grade cabinet solutions
