DOYIN 4SDS5-1500W (2.0HP) DC Solar Submersible Water Pump — 168m Head, 5.0m³/h Flow

The DOYIN 4SDS5-1500W is a high-head DC submersible solar water pump engineered for demanding water extraction from deep wells and boreholes across Kenya. As grid electricity becomes more expensive and less reliable in many rural and peri-urban areas, solar-powered submersible pumps like this one have become the preferred choice for farmers, homeowners, and commercial water suppliers who need consistent water access without ongoing fuel or electricity costs. This particular model sits in the middle of the DOYIN 4SDS5 range — more powerful than entry-level shallow-well pumps, but more energy-efficient and affordable to run than the 3HP and 4HP units built for extreme depths.

Specifications

Key Features & Benefits

• Exceptional Lifting Capacity — With a maximum head of 168 metres, this pump is built to lift water from genuinely deep sources, not just shallow wells. That head rating determines how far vertically the pump can push water against gravity, so it’s a critical spec for anyone with a borehole test report showing water sitting well below ground level.
• High Water Flow — At up to 5.0 m³/h (5,000 litres per hour), the pump delivers enough volume for household use, livestock watering, and moderate irrigation needs without long wait times to fill storage tanks.
• Solar-Powered Efficiency — Running directly on DC power from a solar array means no diesel generator, no fuel deliveries, and no dependence on an unreliable grid connection. Once the solar panel array and pump are installed, daily operating costs drop close to zero.
• Durable Stainless Steel Construction — The pump body is built from stainless steel, which resists the corrosion that can quickly degrade cheaper pumps when exposed to borehole water with dissolved minerals or slightly acidic conditions.
• Energy-Efficient Motor System (4 × 550W) — The motor configuration is designed to make the most of available solar input, converting sunlight into consistent pumping power even as solar irradiance shifts through the day.
• Low Maintenance Design — With no fuel systems, spark plugs, or combustion components to service, submersible solar pumps like this one typically require far less routine maintenance than diesel or petrol-powered alternatives.

Why Choose the 4SDS5-1500W?

This model strikes a practical balance between lifting performance and running cost. It’s powerful enough for genuinely deep wells (up to 139m recommended depth) without the higher solar panel investment required by the 3HP or 4HP versions in the range. For many Kenyan households and small-to-medium farms, this makes it the more cost-effective choice — delivering the flow rate and head needed for daily use without oversizing the solar array. The rugged stainless steel body also means the investment holds up over years of continuous outdoor and underwater operation, which matters in remote locations where technician call-outs are costly and infrequent.

Applications

• Agricultural Irrigation — Suitable for crops, greenhouses, orchards, and drip or sprinkler irrigation systems that need a steady daily water supply.
• Livestock Watering — Provides a dependable water source for farms and animal operations, particularly useful where grid power is unavailable or unreliable.
• Residential Water Supply — Draws water efficiently from deep boreholes and wells for household use, including storage tank filling.
• Commercial Water Systems — Supports water transfer and supply for lodges, schools, and other commercial or institutional facilities off the main grid.
• Remote & Off-Grid Locations — Purpose-built for areas without reliable grid access, where solar is often the only practical long-term power source.

Sizing and Installation

Getting the right pump for your borehole depends on your recent test pumping report (which shows recharge rate and water level), your daily water demand, and how the solar panel array is sized relative to the pump’s power rating. Rhema Solar Energy Solutions Limited supplies, delivers, and installs the DOYIN 4SDS5-1500W across Kenya, including guidance on matching solar panel capacity to the pump’s 1500W rating for reliable year-round performance.
