4SDS5 800W (1.0HP) DC Solar Submersible Water Pump Ordinary Impeller — 1.25" Outlet

The 4SDS5-800W is a 1.0HP DC solar submersible pump built for deeper boreholes and wells, rated for up to 59 metres recommended depth (80M max head), while still delivering up to 5,000 litres per hour through its 1.25-inch outlet. It's a strong option for households, small farms, and community water points needing more lifting power than the 0.75HP models in the range.

This model runs on a DC voltage range of 90–160V, requiring 2 solar panels wired in series to reach the correct operating voltage. Compared to the 600W model, it needs higher-voltage panels but keeps the same simple 2-panel configuration — a practical upgrade for coastal properties in Mombasa, Malindi, Diani, Kilifi, and Lamu with deeper boreholes or greater water demand.

As a direct DC solar pump, it operates without batteries during daylight hours, keeping installation straightforward and maintenance low for coastal homes, farms, and beach properties facing unreliable grid power.

CoastalSolar Africa supplies, sizes, and installs the 4SDS5-800W pump with the correct panel configuration matched to your borehole depth and site conditions across the coastal region.

FAQs:

How many solar panels does the 4SDS5-800W need?
This pump is rated for 2 x 550W panels (roughly 1,100W total), wired in series to reach its 90–160V DC operating range.

How does this compare to the 4SDS5-600W?
Both use a 2-panel setup, but the 800W model needs higher-voltage panels (90–160V vs 65–100V) and can pump from a greater depth (59M vs 41M recommended).

What depth can this pump handle?
It's rated for a recommended depth of 0–59M, with a maximum head of 80M.

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.
