4 inch water-cooled HV DC brushless solar pump with external controller Hydraulic Performance Curves
How to choose a solar pump:
1. Confirm your technical requirements
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)? 


2. 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.

4 inch water-cooled AC/DC brushless solar water pump Packaging
What we get for you: (Package Include)
- 1 x 4 inch AC/DC solar water-cooled pump with 2m cable
- 1 x AC/DC auto-switching controller with MPPT function
- 1 x Stainless steel or plastic float switch (sensor for tank)
- 1 x Pump outlet joint connector
- 1 x Splice kit for cable join
- 1 x Splice kit for waterproof
What You need to get by yourself: (Package DO NOT Include)
- Suitable solar panels. There’re some suggestions in the instruction book.- A stainless steel wire ( called safety cable) to hold pump in bore. If pumping water from dam or river, a float set up is required.
- Poly pipe from pump to the water tank. ( recommend 1.25inch or over-diameter poly pipe)
- Wire power cable (3 wires plus earth). we recommend cable size at least can't chicker than the original cable in the pump.
4 inch water-cooled AC/DC brushless solar water pump FAQ
What is the difference Between AC/DC Hybrid solar power Water Pump and DC solar water pump?
AC/DC solar powered water pump is avaliable for both Alternating Current power and solar energy, which allows the pump work in the low or non sunlight hours.
What if the product has quality problems?
2 years warranty. Any quality problem, please send the photo or video to us for checking, we will guide you to solve the problem online. If the quality problem can’t be solved by yourself, we can send the spare parts to you for replacement.

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.
