INVT 2.2kW (3 HP) Three-Phase Hybrid Solar Water Pumping Inverter | Model: GD100-2R2G-4-PV

The INVT 2.2kW Three-Phase Hybrid Solar Pumping Inverter is a smart, compact variable frequency drive (VFD) engineered to power standard three-phase AC submersible and surface water pumps up to 2200 Watts. This inverter offers the perfect entry point for coastal properties looking to transition away from expensive grid tariffs and unreliable diesel-powered pumping, replacing them with clean, fully automated solar infrastructure.

A standout engineering advantage of the INVT 2.2kW model is its compatibility with an external low-voltage DC boost module . For smaller 3 HP systems, this means the inverter can initiate pumping with a significantly smaller string of solar panels. By lowering the required startup voltage threshold, it reduces upfront solar hardware costs while maintaining exceptional water production during low-light early mornings and overcast coastal days.

Marine-Grade Operational Architecture

Designed to handle the unique climate of coastal East Africa, this inverter features an optimized internal layout designed to withstand heavy salt humidity and high temperatures. Utilizing premium, high-efficiency cooling pathways, it manages full-load operational requirements smoothly. It includes smart, built-in thermal de-rating protections that ensure the drive continues to operate safely even when ambient temperatures spike up to +50°C in open mainland regions.  

Industry-Specific Benefits (Geo-Targeted Content)

Boutique Beach Hotels & Eco-Lodges (Watamu, Diani Beach, Lamu town)

• Application: Dedicated fresh-water pressure lines, boutique resort swimming pool loops, and small-scale greywater filtration setups.

• The Advantage: Maintain a premium, peaceful guest environment. Operating with an advanced, quiet air-cooling profile, this compact inverter eliminates intrusive motor noise. Thanks to its intelligent hybrid dual-input functionality, it can seamlessly blend DC solar energy with 3-phase national grid power. If clouds lower solar production, it draws minor supplementary power from the grid instantly—keeping the water flowing without interrupting your guests.

Rural Communities, Kiosks & Beach Management Units (BMUs)

• Application: Public fresh-water borehole kiosks, localized livestock watering troughs, and village water supply networks.

• The Advantage: Safeguard remote community infrastructure from costly operator errors. The inverter features fully automated plug-and-play operation with no complex parameters to program. It includes native software logic for dry-run protection to prevent the pump from burning out if the well drops below critical levels, paired with auto-shutoff telemetry when your main distribution storage tanks are completely filled.  

Small-Scale Coastal Agriculture & Aquaculture (Kilifi, Malindi, Kwale)

• Application: Tailored drip-irrigation networks, smallholder vegetable patches, and coastal prawn/fish farm circulation loops.

• The Advantage: Lower your daily overhead to zero. Powered by INVT’s premier 99% efficient Maximum Power Point Tracking (MPPT) algorithm, this drive maximizes pump performance by adapting to real-time daylight variations. It delivers maximum torque to 3 HP pumps right when your crops need water most, boosting seasonal crop yields across Kwale and Kilifi.
