SI3VS4.3-165-200-1500-A/D Solar pumping system Veichi SIxV, 1.5 kW, up to 4.3 m³/h, head up to 165 m

Veichi SIV (SIxV) Household Brushless Solar Pumping Systems — Off-Grid Water Supply Plug-and-Play

The Veichi SIV household autonomous pumping system series (registered as SIxV in our database) is specifically engineered to supply off-grid water to residential households, gardens, greenhouses, and small farms directly from solar PV arrays. This unique range integrates a high-efficiency brushless DC (BLDC) permanent magnet motor with a dedicated solar pump controller enclosed in a robust, outdoor weather-resistant chassis rated IP55. Thanks to quick-connector plug-and-play fittings, mechanical integration onto PV rack supports can be performed directly outdoors without complex cable terminations or buying secondary electrical control enclosures.

Veichi SIV Compatibility Across Pump Types

• Submersible Screw Pumps: Perfectly suited for deep boreholes with diameters from 3 inches and low water yield. Delivers highly stable water heads up to 180 meters at minimal power consumption (from 80 to 1100 Watts).
• Centrifugal Plastic Impeller Pumps: Offers exceptional resilience to sand and small abrasive particles in well water. Delivers flow rates up to 20 m³/h and heads up to 195 meters, ideal for large residential watering loops.
• Submersible Stainless Steel Impeller Pumps: Premium durability, structural rigidity, and corrosion resistance for continuous high-flow off-grid irrigation up to 40 m³/h under heads up to 203 meters.
• Surface Suction Pump Stations: Engineered to draw water from open wells, lakes, rivers, or dynamic elevated storage tanks from depths up to 8-9 meters, distributing it at high pressure.

What Differentiates Veichi SIV from Competitors

The core technological B2C benefit of the Veichi SIV range is its integration with brushless DC (BLDC) permanent magnet motors. These deliver a 30-40% higher efficiency than conventional induction AC pump sets of similar power ratings, letting farmers minimize the size of their PV array.

Range Limitations and Alternatives

• If your agricultural project requires standard high-power three-phase asynchronous AC motors exceeding 1.5 kW — choose the compact Veichi SI21 or the outdoor heavy-duty Veichi SI30 (IP65).

Our Engineering Integration Experience

The Veichi SIV series represents a perfect fit for simple residential greenhouse automated drip watering. The front LED panel displays dynamic output frequency, motor current, DC PV voltage, and motor RPM in real time. We always recommend grounding the IP55 controller chassis during mounting and connecting the standard float switch to trigger dry run prevention if the water well goes dry, safeguarding internal seals.
