4 inch water-cooled 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 4DFPW6-42-72 model matches the solar panel voltage between 90V～120V.
