INVT 5.5kW (7.5 HP) Three-Phase Hybrid Solar Water Pumping Inverter

The INVT 5.5kW Three-Phase Hybrid Solar Pumping Inverter is a heavy-duty, high-performance power solution engineered to drive industrial three-phase AC submersible and surface water pumps up to 5500 Watts. Optimized for demanding commercial and agricultural installations, this inverter leverages smart Variable Frequency Drive (VFD) engineering to deliver highly stable, balanced three-phase power directly from clean solar energy.

Featuring intelligent dual-input hybrid functionality, the system eliminates water production downtime. By working simultaneously with DC solar arrays and an auxiliary AC input (national grid or diesel generator), it dynamically transitions between power sources. If coastal weather turns volatile, the inverter instantly covers the power gap via the AC input, achieving reliable, 24-hour unattended water management.

Industrial-Grade Resilience for Coastal Deployments

Coastal East Africa presents punishing environmental challenges, including high ambient temperatures and aggressive humidity. The INVT 5.5kW inverter is built with a low-inductance circuit structure that suppresses voltage peaks, drastically reinforcing internal component lifespan. Equipped with an advanced, automated thermal de-rating safeguard, the system smoothly handles ambient temperatures up to +50°C, making it exceptionally reliable across Mombasa, Lamu, and the hot mainland interior.

Industry-Specific Benefits

Large-Scale Horticulture & Floriculture (Kilifi, Malindi, Kwale)

• Application: High-pressure overhead sprinklers, pivot irrigation, and large-scale ranch livestock watering.

• The Advantage: For commercial farmers growing high-value crops in Kilifi or Kwale, irrigation continuity is everything. The 5.5kW capacity handles deep-well borehole pumps comfortably. Driven by an advanced 99% efficient MPPT tracking algorithm, it maximizes water yield in the early morning and late afternoon, allowing you to move massive volumes of water without spending a single Shilling on diesel fuel.

 Mid-to-Large Scale Resorts & Water Utilities (Diani, Nyali, Watamu, CWWDA)

• Application: Main freshwater reservoir pumping, commercial reverse osmosis (RO) desalinization systems, and large swimming pool circulation arrays.

• The Advantage: This inverter features an advanced sensorless vector control system that automatically tracks motor behavior and auto-tunes parameters as the pump ages. For coastal resorts or water service providers, this eliminates manual system maintenance, dampens heavy motor-start electrical surges, and safeguards expensive submersible pumps from premature mechanical failure.

Bulk Water Supply Kiosks & Fishing Communities (BMUs & Rural Co-ops)

• Application: Community-wide distribution boreholes, water truck filling stations, and high-volume off-grid pumping.

• The Advantage: Built with integrated water management software logic, it supports full, direct automation. Dual terminal links connect seamlessly to well-bottom dry-run sensors and top-level storage tank overflow sensors. The system runs completely hands-free—saving water, preventing pump burnout, and optimizing community assets along the coastline.
