3SDS4 600W (0.75HP) DC Solar Submersible Water Pump — 1" Outlet

The 3SDS4-600W is a 0.75HP DC solar submersible pump built for boreholes and wells up to 58 metres recommended depth (75M max head), delivering up to 4,000 litres per hour. With a 1-inch outlet, it suits domestic water 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 — a compact, affordable setup for homes and small properties in Mombasa, Malindi, Diani, Kilifi, and Lamu where grid power can be unreliable and space for panels may be limited.

Because it runs as a direct DC solar pump, no batteries are needed for daytime operation — water flows as soon as the sun is up, making it a low-maintenance option for coastal boreholes, beach properties, and rural homesteads.

CoastalSolar Africa supplies, sizes, and installs the 3SDS4-600W pump with the correct panel configuration for your borehole depth and site conditions across the coastal region.

FAQs:

How many solar panels does the 3SDS4-600W need?
This pump is rated for 2 x 410W panels (roughly 820W total), wired in series to reach its 65–100V DC operating range.

Can I use different wattage panels?
Yes, as long as the combined series voltage stays within the 65–100V range — CoastalSolar Africa can help match panels you already have or recommend the ideal combination.

What depth can this pump handle?
It's rated for a recommended depth of 0–58M, with a maximum head of 75M.

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.
