4.5m³/h 70m Doyin 0.75HP Stainless Steel DC Solar Borehole Pump System Kit 4SPS4.5-600W

The complete kit also includes 80 metres of 2.5mm² 4-core submersible cable, 20 metres of 6mm² PV cable and one cable-splicing kit, providing the main specified electrical connection components for the solar pumping setup.

Actual water output depends on borehole yield, total pumping head, pipe diameter, delivery distance, solar conditions and installation quality. Maximum flow and maximum head represent different operating points and should not be expected simultaneously.

Applications / Use Cases

• 🏠 Domestic Water Supply – suitable for homes and homesteads drawing water from a compatible borehole.
• 🚜 Small-Scale Irrigation – can supply appropriately sized gardens, farms and irrigation systems where required flow and head are within the pump’s capability.
• 🐄 Livestock Watering – useful for supplying water to livestock tanks and troughs.
• 💧 Elevated Tank Filling – suitable for transferring borehole water to storage tanks where the total dynamic head remains within the pump’s operating range.
• 🌱 Gardens & Nurseries – useful for regular water supply to gardens, nurseries and small agricultural plots.
• ☀️ Off-Grid Water Supply – solar-powered configuration for locations with adequate sunlight and limited access to grid electricity.

Installation Notes

A professional borehole assessment is recommended before installing the Doyin 4SPS4.5-600W. The assessment should establish the borehole depth, static and dynamic water levels, borehole yield, required delivery height, pipe diameter, delivery distance and expected daily water demand.

The supplied specification gives a maximum head of 70m, but a separate recommended installation-depth range was not provided for this kit. Pump selection should therefore be based on the site’s total dynamic head, rather than assuming the pump can simply be installed at 70 metres.

Vertical lift, tank elevation, delivery distance and friction losses in the pipework all contribute to the total pumping head.

The two 590W solar panels should be installed in an unshaded position with suitable orientation and secure mounting. Their combined nominal capacity is:

590W × 2 = 1,180W = 1.18kWp

The 80m submersible cable and cable splice should be installed using suitable waterproof connection methods. The 20m PV cable should also be routed and protected appropriately for the installation environment.

Installation scope and any additional components required for the individual site should be confirmed in the final Macire quotation.

Care & Maintenance

• Keep both solar panels clean and free from dust, leaves and bird droppings.
• Periodically inspect the solar-panel mounting structure and electrical connections.
• Protect the 80m submersible cable and 20m PV cable from physical damage.
• Inspect cable connections and the submerged splice where servicing permits.
• Check delivery pipes, valves and fittings for leakage.
• Avoid operating the pump if the borehole water level falls below a safe pumping level.
• Monitor changes in water output that could indicate borehole, pipework, solar or pump issues.
• Inspect storage tanks and associated valves regularly.
• Have electrical faults or significant reductions in pumping performance checked by a qualified technician.
• Follow Doyin’s operating and maintenance instructions for the 4SPS4.5-600W.

Mini FAQ

What is the maximum flow rate of the Doyin 4SPS4.5-600W?

The pump has a maximum flow rate of 4.5m³/h. Actual water output depends on pumping head, borehole conditions, pipework and available solar energy.

What is the maximum head?

The specified maximum head is 70 metres. Maximum head and maximum flow occur at different operating points and should not be expected simultaneously.

How deep can this pump be installed?

A recommended installation-depth range was not provided for this kit. The correct installation depth should be established from the borehole assessment, water levels and the system’s total dynamic head while remaining within the pump’s operating capability.

Is the pump stainless steel?

Yes. This kit is specifically supplied with a Doyin 0.75HP Stainless Steel DC Solar Borehole Pump, model 4SPS4.5-600W.

How many solar panels are included?

The kit contains two 590W solar panels, giving a combined nominal PV array capacity of 1.18kWp.

What submersible cable is supplied?

The kit includes 80 metres of 2.5mm² 4-core submersible cable.

How much PV cable is included?

It includes 20 metres of 6mm² PV cable.

Does the kit include a splicing kit?

Yes. One cable-splicing kit is included.

Can it fill an elevated water tank?

Yes, provided the combined borehole lift, tank elevation, delivery distance and pipe friction remain within the pump’s operating capability.

Is it suitable for irrigation?

It can support small-scale irrigation where the required water volume and pumping head match the 4SPS4.5-600W’s performance. Site-specific sizing should be completed before installation.
