High-Power Solar Pump 3-37 kW for 4, 6, 8-Inch Wells

high-power solar submersible pump for 6-inch and 8-inch wells, full length view

Overview

This is the irrigation end of the range. From 3 kW up to 37 kW, these pumps are built for 6-inch and 8-inch wells and for volumes a farm cannot move by hand — up to 150 m³/h. They run on a 380 or 520 V DC array through an MPPT controller, and the A/D versions will switch to three-phase mains or a generator when the sun is not enough. At this size the array is a real capital item, so the sizing conversation matters more than the pump price.

Key Features

Up to 150 m³/h — Volumes that suit centre-pivot, large drip blocks and reservoir filling, not garden watering.

Built for 6-inch and 8-inch wells — Larger body and motor stack; the 4/6 models fit both 4-inch and 6-inch casings.

380 V and 520 V DC input — Higher array voltage reduces cable losses on the long runs these installations usually have.

Head to 168 m — Deep static levels still work at high flow, which is where low-head pumps fall short.

AC/DC automatic switching — Falls back to three-phase mains or a generator when PV output drops.

Model code: 4/6 or 6/8 = compatible well sizes, DSC/DPC = impeller type, then max flow (m³/h) – max head (m) – DC input voltage – motor power (W). Specifications may be updated by the plant — confirm current values with us before ordering.

Applications

Large-scale irrigation: centre pivot, drip blocks, sprinkler systems; filling storage reservoirs and tanks; mine and quarry water supply; municipal and village water schemes; fish farm and agricultural processing water.

Frequently Asked Questions

How big an array does a 15 kW pump need?

Roughly 1.3 times the motor rating as a starting point, more if your irradiation is low or the head is at the top of the range. That is around 20 kWp for a 15 kW pump, and it is a significant cost — which is why we size it against your actual daily water requirement rather than the nameplate.

Can these run on a generator instead of solar?

The A/D models can and will switch automatically. At this power level many customers run solar by day and a generator as backup, and the controller handles the changeover.

Do you quote the panels and the mounting too?

We quote the pump, motor and controller. Panels, mounting structures and cabling are usually sourced locally to avoid freight on fragile goods — tell us what you already have and we will scope the rest.
