Description
Overview
The 4SD4/6 is a 1.1 kW solar borehole pump kit that lifts water up to 58 m at up to 6.8 m³/h, and keeps running on mains or generator power when the sun drops out. It pairs a stainless steel 4 inch submersible wet end with a brushless DC motor and a hybrid AC/DC inverter, so one controller handles both solar and backup supply.
The kit is built around a 2,200 W array: 4 standard 550 W panels wired together at 450V/150V. 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 44 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 4SD4/6 solar borehole pump kit, 41 m head and the 4SD4/24 solar borehole pump kit, 142 m head.
Key features
- Hybrid solar system: runs on solar power during the day and draws AC mains or generator power automatically when the sun is not enough
- Stainless steel 4 inch submersible wet end with a brushless DC motor and 100% copper windings
- Hybrid AC/DC inverter is included, so no separate changeover gear is needed
- 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
Typical jobs are stock watering in the Northern Cape and Karoo, small-scale irrigation in the Western Cape, and community water points where a failed pump means a long walk for water. The hybrid inverter keeps supply going through a run of overcast days or an outage on the farm line.

Questions about this product
How many solar panels do I need to run the 4SD4/6 at 58 m head?
The kit is designed for 4 standard 550 W panels, a 2,200 W array wired together at 450V/150V. 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.
What happens on a cloudy day or at night?
Because the inverter is hybrid, it draws AC power from the mains or a generator automatically when solar output drops, so water keeps flowing. Without a backup supply the pump slows and stops with the sun, so we still recommend a storage tank sized for a day or two of use on any solar borehole system.
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 44 m, with a maximum head of 58 m and up to 6.8 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 4SD4/6 kit to Durban?
Yes. We deliver with our own trucks from Polokwane to all nine provinces in 1 to 3 days, including Durban. This kit ships at about 25 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.
