ADA 0.5kw~75kw MPPT solar water pumping inverter

Product Description

SPI series inverters are developed specially for solar pumping system, based on the core control arithmetic of vector control inverters, combined with the control requirements of solar pumping system. It build-in the functions of maximum power point tracking (MPPT), dormant at weak light, wake up at strong light, high water level dormant, under-load pre-warning and other control protection functions, it ensures normal operation of water pumping system.

System Configuration

1. Identify the water pump power according to the water flow and well head, ref. following form


  2.  Comfirm solar pumping Inverter/controller power which should be 1.36 times of water pump power.

  3.  Confirm solar power and series/parallel method.

     3.1   solar panels power is 1.3 - 2 times of pump power, optimize 1.5times.

     3.2   Confirm the series solar panel quantity

              For single phase AC pump, recommended input voltage is  300-400Vdc,  best 360Vdc.

              For three phase AC pump, recommended input voltage is 500-650Vdc, best 540Vdc.

     3.3   Confirm the parallel strings quantity according to total solar panel power and series quantity.

4. Pick up other secondary material, eg. pipe, cable, valve.
