4 inch water-cooled HV DC brushless solar pump with external controller Hydraulic Performance Curves

How to choose a solar pump:

Confirm you technical requiremt

How deep is your well (borehole)?
What is the distance between the tank and the well?
What is the height of the tank?
What is your requirement for the flow rate (L/H)?

Choose solar pumps according to your needs

Calculate the “actual lift needed” and find an appropriate pump.
Then choose the most suitable pump according to different flow rates and prices as well as pump materials.

How To Choose Solar Panel

The solar PV system voltage needs to meet the voltage range in the figure below. For example: The 4DFPW6-56-110 model matches the solar panel ac voltage between 85V～280V and dc voltage between 100V~350V.
