About Zhejiang Senwei Wind Power Generator Corp - Turbines Supplier in China

Zhejiang Senwei Wind Power Generator Corp is based in China and currently lists nine active products. The catalogue is organized under three primary categories: wind turbines, DC/AC inverters and converters, and electric power generators. Product entries include wind turbine generators ranging from 1 kW to 50 kW and a grid‑tie inverter that falls under HS chapter 85.40 for electrical machinery. The supplier’s product set reflects small‑scale and modular wind power solutions commonly used for remote or off‑grid installations. All items are described with their nominal power rating and basic material composition where available.

The wind turbine line comprises models labelled 1 kW, 2 kW, 3 kW, 5 kW, 10 kW, 20 kW, 30 kW and 50 kW, each identified as a wind turbine generator. The inverter is listed as a China Wind Grid Tie Inverter with HS code 8504.40 and a construction that includes aluminum housing, copper wiring and DSP/IGBT electronics. No additional HS codes are provided for the turbine models, which are typically classified under HS 8502 for electric generators driven by wind turbines. The catalogue does not specify certification status, so buyers should verify compliance with relevant standards. Product descriptions focus on power output and basic component materials rather than detailed performance parameters.

Product Range and Specialties of Zhejiang Senwei Wind Power Generator Corp

The turbine portfolio spans rated powers from 1 kW to 50 kW, a range that aligns with IEC 61400‑2 specifications for small wind turbines. Typical small‑scale units in this class feature rotor diameters between 2 m and 6 m, tower heights of 5 m to 15 m, cut‑in wind speeds of 3 - 4 m/s and cut‑out speeds around 25 m/s. Materials commonly include steel towers, fiberglass or aluminum blades, and copper generators, matching the material hints in the catalogue. Buyers in the renewable‑energy sector often request IEC‑type test reports that confirm power curves, noise levels and durability for each rating.

The grid‑tie inverter listed under HS 8504.40 is built with an aluminum housing, copper wiring and DSP/IGBT power electronics, which is standard for inverters handling up to several hundred kilowatts. Industry practice for such converters includes efficiency ratings of 96 % or higher, compliance with IEC 62109‑1 safety standards and, for export, CE marking or equivalent national approvals. Typical specifications also cover input voltage range (e.g., 150‑560 V DC), output voltage (e.g., 230/400 V AC), and grid‑support functions such as reactive power control. These parameters are not detailed in the supplier’s brief description but are routinely demanded by buyers for system integration.

Trade and Export Information - Zhejiang Senwei Wind Power Generator Corp

China is a major exporter of small‑scale wind turbines and associated power electronics, with primary destination regions including Southeast Asia, East Africa, Latin America and the Middle East. HS 8502 covers wind‑driven electric generators, while HS 8504.40 applies to static converters such as the listed grid‑tie inverter; customs authorities in importing countries often require test certificates, CE or IEC conformity, and a pre‑shipment inspection report. Export shipments are typically packed in wooden crates or steel frames and loaded into 20‑ft or 40‑ft containers, with FOB or CIF terms most commonly used for these equipment categories. Chinese manufacturers frequently work with third‑party inspection agencies to verify compliance with IEC standards before loading, which facilitates smoother clearance in the destination market.

Sourcing from Zhejiang Senwei Wind Power Generator Corp - Buyer Guidance

When sourcing from Zhejiang Senwei, request IEC 61400‑2 test data for each turbine model, including power curves, start‑up wind speed and noise measurements. For the inverter, ask for IEC 62109‑1 safety test reports, efficiency charts and a declaration of conformity to CE or the destination country’s grid code. Verify the material list (aluminum housing, copper wiring, DSP/IGBT modules) against the supplier’s packaging details and confirm that the units are shipped in climate‑controlled crates to prevent corrosion. Request a factory‑acceptance test report and a warranty statement that specifies the coverage period for mechanical and electrical components before finalizing the order.

What power ratings are available for the wind turbine generators?

The catalogue lists turbine generators at 1 kW, 2 kW, 3 kW, 5 kW, 10 kW, 20 kW, 30 kW and 50 kW nominal output.

Which HS code applies to the grid‑tie inverter?

The inverter is classified under HS code 8504.40, which covers static converters for electricity.

What materials are used in the inverter construction?

The inverter uses an aluminum housing, copper wiring and DSP/IGBT electronic components, as stated in the product details.

Are there standard certifications buyers should request for these products?

Buyers should request IEC 61400‑2 certification for the turbines and IEC 62109‑1 safety certification for the inverter, along with any CE or ISO 9001 documentation the supplier can provide.

What typical packaging is used for shipping wind turbines from China?

Small wind turbines are usually packed in wooden crates or steel frames and loaded into 20‑ft or 40‑ft containers to protect the rotor, tower and generator during transit.

Which regions commonly import small wind turbines and inverters from China?

Typical import markets include Southeast Asian countries, East African nations, Latin American states and Middle‑Eastern regions that are expanding renewable‑energy capacity.

What documentation is advisable before placing an order?

Request performance test reports, IEC conformity certificates, a pre‑shipment inspection report and a detailed warranty statement covering mechanical and electrical parts.

What are the usual lead times for these wind turbine generators?

Lead times for small‑scale turbines and inverters from China generally range from 30 to 60 days, depending on order size and required testing.
