Tired of electricity bills or fuel costs associated with water pumping, that ultimately eat profits from your business ventures? Ufundi Group brings the plug-and-play solar upgrade that powers any existing AC water pump—single-phase or three-phase, surface or submersible—straight from the sun. No rip-out. No batteries. Just reliable, free solar power from dawn to dusk.
Works on Every Water Pump You Already Own
This solution runs single-phase pumps at 220–240V—common in homes, smallholder farms, and irrigation boosters. It also powers three-phase pumps at 380–415V, built for heavy-duty submersibles or large-scale agriculture. Whether you have a surface pump—centrifugal, jet, or multistage sitting topside—or a submersible pump buried deep in a borehole, your pump can go solar. Yes—even your 20-year-old Grundfos, Pedrollo, Dayliff, or Lorentz AC pump can be solarized tomorrow.
The Magic: Hybrid Solar Inverters (DC → AC Conversion)
These smart inverters take DC power from solar panels and convert it instantly to stable AC—exactly what your pump needs to run at full speed, even during cloudy rainy seasons.
Grundfos RSI inverters are perfect for large three-phase submersibles, handling 2.2 to 250 kW with an IP66 rating built for dusty dry seasons or muddy fields. Solartech offers hybrid models from 5 to 20 kW with MPPT technology and automatic switching between solar and grid—ideal for hybrid farms. Veikong delivers budget-friendly, high-efficiency inverters from 10 to 50 kW, complete with cloud monitoring via SMS or app and performance boosts on cloudy days. Hobertek provides portable, plug-and-play units from 5 to 15 kW with app-based control and a compact design—perfect for mobile irrigation in refugee settlements or remote villages.
How It Works – Step by Step (No Batteries Needed)
- Check Your Pump. Note the kilowatts(kW)horsepower (HP), voltage (220V or 380V), phase (single or three), and daily run hours (e.g., 5 hours for irrigation) of your pump.
- Size Your Solar Panels. Mount panels south-facing at a 5-15° tilt—perfect for Uganda’s near-equatorial sun (5–6 peak sun hours daily).
- Pick the Right Inverter Match the inverter to your pump’s voltage and phase. Add 20% extra capacity to handle startup surges (common with submersibles).
- Wire It Up Connect: Solar Panels → Hybrid Inverter → Your AC Pump. No digging boreholes again. No rewiring the well. Installation takes one afternoon—even in rural areas.
- Run All Day on Sunshine The system auto-starts at dawn, runs at full speed, and shuts off at dusk. For 24/7 water access, add a float switch and elevated tank—gravity does the rest.
Real Results Anticipated
Before going solar, clients pay huge monthly sums on grid bills and refilled petrol or diesel every week at high costs. Pumps can fail during blackouts, and operations carry a high carbon footprint. After the upgrade, energy costs will drop to UGX 0 with free solar power. There’s zero fuel, zero noise, pumps run 100% off-grid, and water pumping, irrigation et al now become carbon-neutral.
