Applications
WBS DFS-series Hybrid AC/DC Solar Submersible Pumps are fitted with a permanent magnet, brushless motor, Which enables the efficient use of energy from a wide range of supply options.


The pump system offers the perfect water supply solution in remote areas where water is scarce and the power supply is non-existent or unreliable.

The structure of motor with double shields poses no pollution risk to drinking water.

The integrated control system is built inside the motor to make it more compatible and reliable, while offering the MPPT function-Maximum Power Point Tracking, maximizing the utilization of power generated from the photovoltaic generator.
Its main application scenes are:

The 4-inch AC/DC Hybrid solar well bore pump with stainless steel impeller for Irrigation, poultry farming, drip irrigation, Fountain system and garden irrigation.

Features
1. Water-cooled motor, safe and poses no pollution risk to drinking water.

2. Advanced brushless dc motor, saving energy and offering maximum efficiency: In DC mode, the MPPT function can achieve over 99% efficiency.

3. Motor-Built-in controller, with MPPT and DSP Technology, offering the easiest and simplest installation. Can be submersible up to 150m underwater.

4. Intelligent frequency conversion algorithm, maximizing efficiency and saving energy.

5. A high degree of flexibility with regards to power supply and power range,offering a wide range of power sources to choose from.

6. Can be powered from the mains and/ or power generators, guaranteeing operation day or night.

7. Two years warranty.

About installation
What we get for you (Package Include)

- 1x 4 inch AC/DC S/S impeller solar submersible bore pump(controller built-in)

- 1x Pump outlet joint connector

- 1x Splice kit for cable join

- 1x 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.

- Stainless steel wires ( called safety cable) to hold pump in bore. If pumping water from dam or river, a float set up required.

- Poly pipes from pump to water tank.

- Wire power cable (2 wires plus earth). we recommend cable size at least chicker than the original cable in the pump.

About Dry-run Protection
The pump has dry-run protection. So low level sensors are not needed.
