4SDS5 600W (0.75HP) DC Solar Submersible Water Pump Ordinary Impeller — 1.25" Outlet

The 4SDS5-600W is a 0.75HP DC solar submersible pump built for boreholes and wells up to 41 metres recommended depth (55M max head), delivering up to 5,000 litres per hour — a higher flow rate than the smaller 3SDS4 series, thanks to its larger 1.25-inch outlet. It's well suited to domestic supply, small farms, poultry units, and community water points across coastal Kenya.

This model runs on a DC voltage range of 65–100V, requiring just 2 solar panels wired in series to reach the correct operating voltage — an affordable, compact setup for homes and small-to-mid properties in Mombasa, Malindi, Diani, Kilifi, and Lamu where grid power is unreliable and higher water flow is needed than a basic domestic pump provides.

As a direct DC solar pump, it needs no batteries for daytime operation — water flows as soon as the sun is up, keeping the system simple and low-maintenance for coastal boreholes, beach properties, and farms.

CoastalSolar Africa supplies, sizes, and installs the 4SDS5-600W pump with the correct panel configuration for your borehole depth and site conditions across the coastal region.

FAQs:

How many solar panels does the 4SDS5-600W need?
This pump is rated for 2 x 410W panels (roughly 820W total), wired in series to reach its 65–100V DC operating range.

How does this compare to the 3SDS4-600W?
Both use the same panel setup (2 x 410W) and voltage range, but the 4SDS5-600W has a larger 1.25" outlet and higher flow rate (5,000L/h vs 4,000L/h), though a shallower recommended depth (41M vs 58M).

What depth can this pump handle?
It's rated for a recommended depth of 0–41M, with a maximum head of 55M.

Do I need batteries for this pump?
No — it runs directly off solar panels during daylight hours. Batteries are optional if you need water access after sunset.

Do you install this pump in Kilifi and Malindi?
Yes, CoastalSolar Africa supplies and installs across Mombasa, Malindi, Diani, Kilifi, Lamu, and the wider coastal region, including correct panel sizing on-site.
