DC Solar Submersible Water Pump

The Suntrica 2DPC DC solar submersible water pump series is a compact 2-inch clean-water range for narrow wells, household supply, garden irrigation and small farm applications. The models listed on this page use 24V or 48V DC motors with rated power from 200W to 400W.

The listed models cover maximum flow values from 1.5 to 1.7 m3/h and maximum head values from 35 to 64 m. Maximum flow and maximum head are separate pump-curve endpoints, so the final model must be selected at the required operating flow and total dynamic head. A compatible DC controller is required; batteries are not required for properly configured daylight pumping.

How the System Works

The DC solar submersible water pump works with solar panels through a dedicated controller. The controller regulates input power and helps ensure stable operation under changing sunlight conditions.

Solar panel provides DC power input
Controller regulates and protects the system
Pump lifts water from well or borehole
Water level sensor can be connected if required
Battery connection can be added in some configurations

How to Choose the Right Model

To choose a suitable model, customers should confirm well depth, water level, required flow, lifting distance, and daily water demand. Proper model selection helps the pump system run more efficiently and reliably.

Correct solar panel and controller matching is also important, especially for projects with limited sunshine conditions or higher daily water requirements.

Check actual water level depth
Measure required vertical head accurately
Confirm required daily flow demand
Match solar panel voltage and power correctly

FAQ

1. What kind of water is this pump suitable for?

This pump is suitable for clean water applications such as domestic water supply, garden irrigation, and small farm use.

2. Can it work directly with solar panels?

The pump works with solar panels through a compatible DC controller, which manages the variable PV input and system protection. Read how a solar water pump runs without batteries before choosing the system layout.

3. Is it suitable for narrow wells?

Yes. The compact 2-inch structure makes it suitable for narrow wells and small borehole applications.

4. What information is needed before model selection?

Please provide required flow, total dynamic head, well depth, pumping water level, pipe details, daily demand and installation location. Use this solar water pump sizing guide to prepare the data.
