0.75kW 4-Inch Solar Borehole Pump System — Medium-Capacity Off-Grid Water
Step up your water pumping capacity with the 0.75kW solar borehole pump system. Capable of pumping from depths up to 100m and delivering 2–4m³ per hour, this system suits medium-sized farms, smallholdings with livestock, market gardens, and rural properties where the 0.37kW model is insufficient.

Daily Water Output
In South Africa’s sunny climate (5–7 peak sun hours), the 0.75kW system can pump 10,000–24,000 litres per day into storage tanks — more than enough for a small farm, multiple livestock troughs, or a market garden irrigation system.
Protection Features
The MPPT pump controller includes comprehensive protection: dry-run shutdown (prevents motor burnout if water runs out), automatic restart when water recovers, under-voltage cutoff during cloudy weather, and over-temperature protection. This ensures long pump life with minimal maintenance.
FAQ
How many solar panels are needed for the 0.75kW pump?
Minimum 900W of solar panels (e.g., 3x 300W). For optimal performance and higher daily output, 4–6 panels are recommended. Panels should be high-efficiency monocrystalline for best results in South African conditions.
Can I add a float switch to automatically stop when the tank is full?
Yes. The MPPT controller includes a dry-run and float switch input terminal for automatic stop when the storage tank reaches capacity.
What is the difference between the 0.37kW and 0.75kW systems?
The 0.75kW pumps from greater depth (100m vs 60m) and delivers twice the flow rate. Choose the 0.75kW if your borehole is deeper than 60m or if you need more than 2m³/hour flow for irrigation or livestock.
