Veichi 11kW (15 HP) Three-Phase Hybrid Solar Water Pumping Inverter | SI23 Series

The Veichi 11kW Three-Phase Hybrid Solar Pumping Inverter (Model: SI23-D5-011G) represents the next generation of smart, high-efficiency fluid control architecture. Custom-engineered to drive heavy-duty three-phase AC pumps up to 11,000 Watts, this industrial-tier variable frequency drive (VFD) optimizes water production entirely from solar arrays, dramatically slashing overhead costs associated with utility grids and diesel fuel.

The defining feature of the SI23 series is its advanced, industry-leading software control algorithm. It supports synchronized drive integration—meaning it can seamlessly self-tune and run everything from standard AC induction motors to ultra-efficient Permanent Magnet Synchronous Motors (PMSM). Driven by high-bandwidth current vector control and intelligent Maximum Power Point Tracking (MPPT), this inverter extracts up to 30% more water volume during low-light early mornings and patchy coastal cloud conditions.

Marine-Resilient Book Design for Coastal Demands

Real estate inside utility rooms is expensive, and coastal air is corrosive. Veichi solves both challenges with its innovative book-style narrow-body structure, reducing physical installation volume by up to 60%. Internally, it features an isolated air duct layout: the core electronics are completely separated from the high-velocity, wide-tooth heat dissipation surfaces. This prevents corrosive, salt-laden coastal humidity from contacting delicate circuitry, ensuring continuous full-power operation up to +60°C across Mombasa, Kilifi, and the Lamu archipelago without thermal derating.

Industry-Specific Benefits (Geo-Targeted Content)

Large Horticulture Farms & Agri-Ranches (Kilifi, Malindi, Kwale)

• Application: High-volume drip arrays, center-pivot water supply feeding, and multi-point livestock watering.

• The Advantage: Sizing water systems for deep agricultural wells requires relentless torque. Delivering a strong 25A rated output current, this unit drives 15 HP submersible pumps smoothly. Its unique "Custom PQ Curve" tracking software lets you monitor accumulated flow and solar power conversion directly, giving farm managers empirical data to calculate exact seasonal water yields.

Premium Eco-Lodges & Boutique Resorts (Watamu, Diani Beach, Shimoni)

• Application: Large-scale guest freshwater systems, high-efficiency reverse osmosis desalination loops, and main swimming pool filtration plants.

• The Advantage: Keep your property quiet and perfectly supplied. The hybrid auto-mixing capabilities allow the SI23 to blend DC solar power with 3-phase national grid lines or backup generators simultaneously. The system prioritizes free solar during peak hours and dynamically brings in alternative AC lines if coastal weather shifts, preventing water disruptions for your guests.

Water Utilities & Rural Community Boreholes (CWWDA & Local BMUs)

• Application: Community-managed freshwater distribution kiosks, rural cooperative boreholes, and village pipelines.

• The Advantage: Managing remote coastal water nodes is simplified by Veichi’s advanced Smart IoT compatibility. Through plug-and-play GPRS or 4G telemetry modules, teams can track water flow, monitor system health, and control the pump remotely from a smartphone or PC. Tailor-made solar protective systems natively handle borehole dry-run protection and tank overflow automation, completely preventing hardware damage without on-site technicians.
