Agricultural and Commercial Applications
At 1.5kW, this system handles medium-scale agricultural irrigation using drip or pivot irrigation, filling large storage dams and reservoirs, supplying water to game farms and eco-lodges, and providing municipal-quality water supply to small communities in off-grid areas of South Africa.
Optional GSM Monitoring
The 1.5kW system supports optional GSM modem connectivity for remote pump monitoring and control via smartphone — ideal for farms where the borehole is far from the homestead. Monitor flow rate, pump status, daily water output, and receive SMS alerts for faults or dry-run conditions.
FAQ
Does the 1.5kW pump work with a standard 4-inch borehole?
Yes. The pump is designed for 4-inch (100mm) boreholes and larger. Ensure your borehole has sufficient yield (recharge rate) to sustain the pump’s flow rate — a borehole test by a certified hydrogeologist is recommended before installation.
How much storage capacity is needed?
For a 1.5kW pump producing up to 30,000 litres per day, a minimum of 15,000–20,000 litres of storage (JoJo tanks or concrete reservoir) is recommended to buffer cloudy days.

Gerrie Joubert –
Running a 1.5kW solar borehole pump on our wine farm in Robertson and it has been pumping consistently for eight months. No electricity costs for irrigation during the day, just sunlight. The system came complete and commissioning was straightforward for our electrician. PowerVault was one of the very few suppliers who could supply the complete system including the VFD at a reasonable price. Excellent product.

The 1.5kW Solar Borehole Pump System — 4-Inch Submersible has transformed our house. We went from Stage 6 misery to complete indifference about load shedding. Everything runs normally during outages including the aircon, TV and kitchen appliances. The inverter monitor app is very useful for tracking production and consumption.

Replaced a diesel pump on our smallholding near Tzaneen with this solar borehole system. Running costs dropped to zero during daylight hours and the pump delivers more than enough flow for our vegetable operation. The variable frequency drive handles the solar input variation smoothly. PowerVault’s technical support helped us select the right pump for our borehole depth before we ordered.
