Import 300w Vertical Wind Trbine — Buy in Bulk from Supplier in China

This 300 W vertical-axis wind turbine (VAWT) uses a three-phase permanent magnet alternator to convert low-speed wind into usable electricity, with a rated output of 300 W at design wind speed. The unit features a compact vertical rotor configuration suited to sites with restricted space or variable wind direction, eliminating the need for active yaw control. Construction employs industrial-grade materials, including corrosion-resistant aluminium alloy blades and a steel frame, intended to withstand continuous outdoor exposure. The generator is brushless, which reduces mechanical wear and extends service intervals compared to brushed alternatives.

Vertical turbines of this class typically operate with cut-in wind speeds around 2 m/s and reach rated output between 10 and 12 m/s; survival wind speed is generally 45-50 m/s for units in this category. The permanent magnet generator commonly runs at low RPM, producing variable-frequency AC that requires rectification to DC for battery charging or grid-tied inversion. Blade material selection, typically aluminium or reinforced composite, balances fatigue resistance against centrifugal loading. Bearing assemblies are usually sealed to prevent moisture ingress, a critical factor in humid or coastal climates. Noise emission at distance is typically below 50 dB, though this depends on tip-speed ratio and blade profile.

Buyers include off-grid property owners, telecom tower operators, rural clinics, and small commercial sites seeking supplementary or backup power. The turbine pairs with 12 V or 24 V battery banks through a charge controller, which the buyer must source separately. Installation requires a tower or pole of adequate height, typically 6-10 m above surrounding obstacles, with foundation anchoring suited to local wind load codes. Importers should confirm with Hefei Wind Wing Energy Technology Co., Ltd. whether the controller, tower hardware, and inverter are included or must be procured separately, and whether the unit carries IEC 61400-2 compliance documentation for small wind turbines.

Hefei Wind Wing Energy Technology Co., Ltd. is located at 18 Huguang Road, Shushang, Hefei, Anhui Province, 230000, China. The supplier's tier is marked as 'imported' and its trust tier as 'harbor', which indicates a profile that has passed basic platform verification but carries limited transaction history. The response rate is recorded at 0.00% with an average response time of zero hours, meaning no buyer inquiries have been answered through the platform to date. This absence of engagement history should be factored into due diligence; direct contact outside the platform may be necessary to assess responsiveness.

The listing positions the company as a source of small-scale vertical wind turbines for residential and light commercial use, though no factory size, year of establishment, revenue, or client references are provided. The address places it within Hefei, an industrial hub in central China with established electronics and machinery supply chains. Buyers should verify factory ownership versus trading status, request ISO 9001 or equivalent quality system certification if claimed, and ask for third-party test reports on the 300 W turbine's power curve and mechanical load testing. The company does not state export experience, after-sales support infrastructure, or spare parts availability, each of which should be clarified before order commitment.
