DOYIN 4SF10-234-9200W (12.5HP) AD Hybrid Solar/3-Phase Submersible Pump — 2" Outlet

The DOYIN 4SF10-234-9200W is a heavy-duty 12.5HP AD (hybrid) submersible pump capable of running on solar power or three-phase AC electricity, making it one of the most powerful and flexible pumps in the DOYIN range. With a 2-inch outlet and a flow rate of 14.4m³/h (14,400 litres per hour), it's built for very demanding, high-volume water needs from a recommended depth of up to 371 metres — a maximum head of 400M, placing it among the deepest and highest-capacity pumps DOYIN offers.

This pump suits large-scale agricultural irrigation, commercial water supply, and major community borehole projects requiring both exceptional flow and very deep lifting capacity. As an AD hybrid model, it can run on a solar array during daylight hours (DC 450–750V) and switch to three-phase AC power (380–460V) when solar output drops, giving properties in Mombasa, Malindi, Diani, Kilifi, and Lamu — as well as large inland agricultural operations — continuity of water supply regardless of weather or grid conditions.

Given its scale, the solar configuration requires a substantial array: DOYIN specifies 2 sets of 15 x 450W panels (a total of 30 panels, roughly 13.5kW) to reach the correct operating voltage — a significant investment best suited to large commercial or agricultural projects rather than domestic use.

CoastalSolar Africa supplies, sizes, and installs the 4SF10-234-9200W pump and its full solar array or 3-phase power setup, for large-scale water projects across the coastal region and beyond.

FAQs:

How many solar panels does this pump need?
It requires two sets of 15 x 450W panels — 30 panels in total (roughly 13.5kW) — reflecting its high power draw at this capacity level.

Can this pump run on AC power only, without solar?
Yes, its AD hybrid design allows full operation on 3-phase AC power alone (380–460V) if a solar array isn't installed or available.

What kind of projects is this pump suited for?
Given its scale (12.5HP, 400M max head, 14,400L/h flow), it's intended for large agricultural irrigation schemes, commercial water supply, or major community boreholes rather than typical domestic or small farm use.

What controller does this pump require?
It needs a matching high-capacity AD hybrid controller sized for 9200W/12.5HP operation — CoastalSolar Africa can confirm and supply the correct unit.

Do you supply and install pumps at this scale in coastal Kenya?
Yes, CoastalSolar Africa handles large-scale solar/hybrid pump installations, including full array design, across Mombasa, Malindi, Diani, Kilifi, Lamu, and larger agricultural sites further inland.
