INVT 4kW (5.5 HP) Three-Phase Hybrid Solar Water Pumping Inverter

The INVT 4kW Three-Phase Hybrid Solar Pumping Inverter delivers uncompromising performance for mid-scale, industrial-grade water management systems. Built by INVT, a global leader in variable frequency drives, this hybrid inverter converts solar energy into highly stable three-phase AC power to run submersible and surface water pumps up to 4000 Watts. 

Featuring integrated hybrid automatic-switching technology, this unit flawlessly blends DC solar power with the AC national grid or backup generator power. If clouds roll over the coast, the system instantly compensates for the power drop via your secondary power source—ensuring uninterrupted water production 24 hours a day without manual intervention.

Coastal-Ready Engineering

Operating along the East African coast demands hardware that resists dust, moisture, and high thermal strain. The INVT 4kW inverter features a highly resilient internal design with a built-in EMC/EMI filter to eliminate electromagnetic interference. Boasting advanced automotive-grade electronic protection features—including auto-derating against thermal overloads—it maintains continuous output even in ambient temperatures climbing up to +50°C.

Industry-Specific Benefits (Geo-Targeted Content)

Mid-Scale Farming & Horticulture (Malindi, Kilifi, Kwale Ranches)

• Application: Controlled drip irrigation, micro-sprinklers for cash crops, and livestock watering stations.

• The Advantage: For agricultural investments in Kilifi or Kwale, running a 3-phase pump on diesel generators destroys profitability. The INVT 4kW pays for itself within months by running your pump entirely on solar during prime daylight hours. Built-in PID control dynamically adjusts pump speeds to match daylight intensity, squeezing up to 99% solar tracking efficiency out of your solar arrays.

Boutique Resorts & Eco-Lodges (Watamu, Lamu, Galu Beach)

• Application: Daily freshwater storage feeding, swimming pool filtration loops, and localized reverse osmosis treatment.

• The Advantage: Keep your operations peaceful and green. This unit features advanced natural cooling mechanics that operate in complete silence, eliminating noisy cooling fans that draw in salty, corrosive coastal air. Its highly compact form factor takes up minimal space in your utility rooms.

Local Communities & Beach Management Units (BMUs)

• Application: Public borehole water kiosks, livestock dips, and off-grid rural water distribution networks.

• The Advantage: Water is life in remote coastal settlements. The INVT system features dual terminal connections for automatic water level sensors. It safeguards your valuable equipment by preventing dry-running if the well water drops below critical limits, and shuts off automatically when your water storage tanks are completely full.
