4.5m³/h 98m Doyin 1HP Stainless Steel DC Solar Borehole Pump System Kit 4SPS4.5-800W

The 4.5m³/h 98m Doyin 1HP Stainless Steel DC Solar Borehole Pump System Kit 4SPS4.5-800W is a higher-head solar-powered water-pumping solution designed for boreholes requiring greater vertical lift.

The system combines a Doyin 1HP stainless steel DC borehole pump with two 590W solar panels, providing a total PV array capacity of 1.18kWp. It delivers a maximum flow rate of 4.5m³/h and a maximum head of 98 metres, making it suitable for domestic water supply, livestock watering, elevated tank filling and small-scale irrigation where higher pumping head is required.

The kit also includes 108 metres of 2.5mm² 4-core submersible cable, 20 metres of 6mm² PV cable and one cable-splicing kit. Its solar-powered configuration provides a practical water-pumping solution for locations with adequate sunlight while reducing dependence on grid electricity and fuel-powered pumping.

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.

Installation Notes

A professional borehole assessment is recommended before installing the Doyin 4SPS4.5-800W. The assessment should confirm the borehole depth, static and dynamic water levels, borehole yield, required delivery height, pipe diameter, delivery distance and expected daily water demand.

The pump has a specified maximum head of 98 metres. However, a separate recommended installation-depth range was not provided. The pump should therefore not automatically be treated as suitable for installation at 98 metres depth.

Final suitability should be determined from the total dynamic head, which includes vertical lift, tank elevation and friction losses through the delivery pipe and fittings.

The two 590W solar panels provide:

590W × 2 = 1,180W = 1.18kWp

The panels should be installed in an unshaded position with suitable orientation and secure mounting. Electrical connections should be completed correctly and protected against environmental exposure.

The supplied 108m submersible cable should be routed appropriately within the borehole, and the cable splice should use suitable waterproofing and connection methods. The 20m PV cable should also be properly protected and routed between the solar array and pumping system.

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

Care & Maintenance

• Keep the two 590W solar panels clean and free from dust, leaves and bird droppings.
• Inspect solar-panel mounting structures and electrical connections periodically.
• Protect the 108m submersible cable and 20m PV cable from physical damage.
• Check pipe joints, valves and fittings for leakage.
• Avoid operating the pump if the borehole water level falls below the safe pumping level.
• Monitor water output for unexpected reductions that may indicate borehole, pipework, solar or pump issues.
• Inspect storage tanks, float valves and delivery pipes regularly.
• Keep exposed electrical connections appropriately protected.
• Have electrical faults and reduced pumping performance checked by a qualified technician.
• Follow Doyin operating and maintenance instructions for the 4SPS4.5-800W.

Mini FAQ

What is the maximum flow rate of the Doyin 4SPS4.5-800W?

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

What is the maximum head?

The maximum head is 98 metres. Maximum head and maximum flow occur at different operating points and should not be expected simultaneously.

How deep can the pump be installed?

A recommended installation-depth range was not supplied for this kit. The correct depth should be determined through a borehole assessment considering static and dynamic water levels, borehole yield and total dynamic head.

Does the 98m maximum head mean the pump should be installed 98m deep?

No. Maximum head is not the same as recommended installation depth. Tank elevation, vertical lift and pipe friction also contribute to the total pumping head.

Is this a stainless steel pump?

Yes. The Doyin 4SPS4.5-800W is specified here as a 1HP Stainless Steel DC Solar Borehole Pump.

How many solar panels are included?

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

What submersible cable is included?

The kit contains 108 metres of 2.5mm² 4-core submersible cable.

How much PV cable is supplied?

The system includes 20 metres of 6mm² PV cable.

Does it include a cable-splicing kit?

Yes. One cable-splicing kit is included.

Can it pump into an elevated storage 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 flow and pressure match the pump’s available performance. Site-specific sizing is recommended before installation.
