4000W 5.5HP AC/DC Solar Water Pump – 345M Head
The 4SF5-230-4000W 5.5HP AC/DC Solar Water Pump is a powerful high-head submersible pump designed for deep boreholes and demanding water pumping applications. It delivers a maximum flow rate of 8,400 litres per hour and can achieve a maximum head of up to 345 metres.
Its AC/DC hybrid operation provides greater flexibility. The pump can operate using solar power during the day while offering the option of an alternative AC power source when required.
Powerful 4000W Motor
The pump is powered by a 4000W (5.5HP) motor, providing the power required to lift water from deep boreholes.
With a recommended operating head of 0–293 metres, it is particularly suitable for installations where conventional lower-head solar pumps may not provide sufficient lifting capacity.
High Water Delivery
The 4SF5-230-4000W pump delivers a maximum flow rate of approximately 8.4 m³/h or 8,400 litres per hour.
Actual water output will vary depending on the pumping head, borehole conditions, pipe size, solar irradiation and system configuration.
AC/DC Hybrid Operation
The AC/DC hybrid design provides a practical solution for locations where reliable water supply is important.
Solar panels can provide the primary source of energy, helping reduce dependence on grid electricity and fuel-powered generators. An appropriate AC supply can provide an alternative power source when necessary.
Recommended Solar Panel Configuration
For solar operation, the recommended solar array is:
10 × 550W solar panels
This provides approximately 5,500W of total solar panel capacity.
Correct solar array configuration is important for efficient pump operation. The panels should be installed in a location with good sunlight exposure and minimal shading.
Ideal Applications
This high-head solar submersible pump is suitable for:
- Deep borehole water pumping
- Farm irrigation
- Livestock watering
- Water storage tank filling
- Agricultural water supply
- Domestic water systems
- Commercial water supply
- Remote and off-grid installations
