Description

Overview

The 4SD3/7 at 110 V DC is a 1.1 kW solar borehole pump kit that lifts water up to 98 m at up to 7.5 m³/h with no mains or generator involved. It pairs a stainless steel 4 inch submersible wet end with a brushless DC (BLDC) motor and a matching low-voltage DC solar controller, and suits boreholes that need more flow than a 3 inch kit can give.

The kit is built around a 2,200 W array: 4 standard 550 W panels wired together at 110 V DC. That is deliberately above the motor rating to cover cloud and losses. A different panel wattage changes the count, and our team can confirm the layout.

It is rated for a dynamic water level of about 74 m. For a deeper borehole or a different flow rate, ask us about the other 4SD configurations, which run up to 240 m head. See also the solar borehole pumps range, including the 4SD3/7 solar borehole pump kit, 80 m head and the 4SD3/7 solar borehole pump kit, 61 m head.

Key features

Full DC solar kit: no mains electricity or generator required
Stainless steel 4 inch submersible wet end with a brushless DC motor and 100% copper windings
Matching low-voltage DC solar controller is included
Soft-start control with protection against under-voltage, over-voltage, overload and dry running, with automatic recovery after waterless faults
Maintenance-free and straightforward to install
Fits 4 inch (100 mm) and larger boreholes, wells and reservoirs

Where it works

Smallholders and contractors drilling new boreholes use this kit to get water to surface fast without waiting for Eskom to connect a supply. Pair it with a storage tank sized for a few days of use, because output follows the sun and stops at night.

Questions about this product

How many solar panels do I need to run the 4SD3/7 at 98 m head?

The kit is designed for 4 standard 550 W panels, a 2,200 W array wired together at 110 V DC. That is intentionally above the 1.1 kW motor rating to cover cloud, cable and controller losses. If you use panels of a different wattage the count changes, so tell us what you have and we will confirm the layout for your site.

Will it work without mains power or a generator?

Yes. This is a full DC kit, so no mains or generator is needed. The pump runs on the 110 V DC supply from the panels and slows as the light drops. There is no AC backup, so store the water in a tank to cover evenings and overcast days.

Is this pump right for my borehole?

It fits 4 inch (100 mm) and larger boreholes. The kit is rated for a dynamic water level of about 74 m, with a maximum head of 98 m and up to 7.5 m³/h. If your water level is deeper or you need more flow, ask us about the other 4SD kits in the range, which run up to 240 m head.

Do you deliver the 4SD3/7 kit to Pretoria?

Yes. We deliver with our own trucks from Polokwane to all nine provinces in 1 to 3 days, including Pretoria. This kit ships at about 22 kg, so it falls in the up to 30 kg delivery band (R550). Orders of R20,000 or more (VAT incl.) are delivered free.

Can it pump sandy or dirty water?

It is meant for non-corrosive water with sand content of no more than 1% by volume and a liquid temperature up to 40 °C. A heavily sandy borehole should be developed first, because abrasive water shortens the life of any submersible pump.
