8.4m³/h 412m Doyin 7.5HP AC/DC Hybrid Solar Borehole Pump System Kit 4SF5-300-5500W AD

The 8.4m³/h 412m Doyin 7.5HP AC/DC Hybrid Solar Borehole Pump System Kit 4SF5-300-5500W AD is a very high-head solar borehole pumping system designed for demanding water-lifting projects where extreme pumping head is required together with useful water-transfer capacity.

At the centre of the system is the Doyin 4SF5-300-5500W AD 7.5HP / 5500W AC/DC Hybrid borehole pump, delivering a maximum flow rate of 8.4m³/h and reaching an exceptional 412-metre maximum head. This very high-head capability is the defining feature of the model, positioning it for challenging borehole-to-storage projects involving substantial vertical lift.

The supplied information states 15 × 590W solar panels and a total PV array capacity of 8.26kWp. However, the additional table states 14 panels, and 14 × 590W = 8.26kWp. Therefore, the panel quantity should be confirmed before the final kit specification is published. The package also includes 432m of 2.5mm² 4-core submersible cable, 30m of 6mm² PV cable and one cable-splicing kit.

Its AC/DC Hybrid configuration distinguishes this system from DC-only solar borehole pumps. Exact AC/DC input requirements, electrical protection and operating arrangements should follow Doyin’s technical requirements for the 4SF5-300-5500W AD.

Actual water output depends on borehole yield, total dynamic head, pipe diameter, delivery distance, available power, solar conditions and installation quality. The 8.4m³/h maximum flow and 412m maximum head represent different operating points and should not be expected simultaneously.

Applications / Use Cases

💧 Very High-Head Borehole Pumping – the exceptional 412m maximum head makes this model particularly relevant for demanding water-lifting projects.

🏔️ High-Elevation Water Storage – suitable for appropriately designed borehole-to-tank systems involving considerable elevation between the pumping water level and storage point.

🚜 Agricultural Water Storage – suitable for transferring borehole water to farm storage tanks where the required operating point falls within the pump’s available performance.

🐄 Livestock Water Projects – useful for supplying central storage tanks serving livestock watering points across appropriately designed systems.

🌱 Irrigation Water Storage – its 8.4m³/h maximum flow provides useful water-transfer capacity for suitably sized irrigation storage applications.

🏠 High-Head Borehole-to-Tank Systems – suitable for residential, institutional and other water-storage projects requiring substantial lifting capability.

🔄 AC/DC Hybrid Pumping – suitable where an AC/DC hybrid pump configuration is required rather than relying exclusively on DC solar input.

Installation Notes

A professional borehole assessment should be completed before installing the Doyin 4SF5-300-5500W AD. Important parameters include borehole depth, static water level, dynamic water level, borehole yield, tank elevation, delivery distance, pipe diameter and required daily water volume.

The specified 412m maximum head must not be interpreted as a recommended installation depth of 412m. No separate recommended installation-depth range was supplied.

Correct pump selection should be based on total dynamic head (TDH). TDH includes vertical lift from the pumping water level to the delivery point, tank elevation and friction losses through pipes, fittings, bends and valves.

Solar Array Configuration Check

The supplied information contains two different panel quantities:

14 × 590W = 8,260W = 8.26kWp

15 × 590W = 8,850W = 8.85kWp

Therefore, the stated 8.26kWp PV capacity corresponds to 14 × 590W panels, while 15 × 590W panels would provide 8.85kWp. The intended panel quantity should be confirmed before installation.

The exact series/parallel arrangement of the panels cannot be determined from panel quantity and wattage alone. It must comply with the electrical input limits of the 4SF5-300-5500W AD.

Because this is an AC/DC Hybrid pump, AC and DC connections, electrical protection and operating arrangements should follow Doyin’s exact technical requirements.

The supplied 432m of 2.5mm² 4-core submersible cable should be checked against the final pump position and cable-routing requirements. Cable length does not establish recommended pump installation depth.

The 30m of 6mm² PV cable should be appropriately routed and protected. The submerged connection should be completed using the supplied splicing kit and suitable waterproofing procedures.

Installation scope, pipework and any additional site-specific components should be confirmed in the final Macire quotation.

Care & Maintenance

• Keep the solar panels clean and free from shading.
• Inspect panel mounting structures and PV connections periodically.
• Protect the 432m submersible cable against abrasion and physical damage.
• Inspect the 30m PV cable and accessible electrical connections regularly.
• Periodically inspect AC and DC electrical protection.
• Check delivery pipes, fittings and valves for leaks or restrictions.
• Monitor borehole water levels and avoid pumping below a safe operating water level.
• Monitor water output for unexpected reductions.
• If performance decreases, check borehole yield, dynamic water level, TDH, pipework and available power.
• Have electrical and pumping faults inspected by a qualified technician.
• Follow Doyin operating and maintenance requirements for the 4SF5-300-5500W AD.

Mini FAQ

What is the maximum flow rate?

The Doyin 4SF5-300-5500W AD provides a maximum flow rate of 8.4m³/h.

What is the maximum head?

The pump reaches an exceptional 412m maximum head, making very high-head pumping the defining characteristic of this configuration.

Will it deliver 8.4m³/h at 412m head?

This should not be assumed. 8.4m³/h maximum flow and 412m maximum head represent different operating points. Actual water delivery at the project’s operating head should be confirmed from the applicable pump performance data.

Can the pump be installed 412m deep?

The 412m figure is maximum head, not recommended installation depth. Correct installation depth depends on the borehole’s static and dynamic water levels, yield and total dynamic head.

What power is the pump?

The 4SF5-300-5500W AD is specified as a 7.5HP / 5500W AC/DC Hybrid borehole pump.

How many 590W panels are required?

The supplied details contain conflicting quantities. 14 × 590W equals the stated 8.26kWp, while 15 × 590W equals 8.85kWp. The intended kit configuration should therefore be confirmed.

How much submersible cable is included?

The kit includes 432 metres of 2.5mm² 4-core submersible cable.

How much PV cable is supplied?

The package includes 30 metres of 6mm² PV cable.

Is a splicing kit included?

Yes. The kit includes one cable-splicing kit.
