VEICHI-SI10 Variable Frequency Drive is positioned in environmental-friendly and economical PV market, the product is applicable to PV pumping system, replaces water storage with electric storage and needs no battery modules. The direct current generated by solar modules is input to the inverter and then converted into the alternating current to drive various pumps directly. Additionally, the output frequency is adjustable in real time according to sunlight intensity change.


200 -400VDC input, 220VAC output, 0.75 to 3.7kw

350-780VDC input, 380VAC output, 0.75 to 160kw.

Descriptions and Features:

  • Internal diagnostics will tolerate a lower input voltage
  • Whenever possible, the controller attempts to regulate the pump load in a manner that optimizes for maximum power transfer from the solar array.
  • The drive manually switches to AC backup power( when available) if the DC primary source is unable to support pump operation
  • TI/Fuji DSP technology and Infineon PIM design, high quality.
  • MPPT function is available , CVT function  also is available.
