1kW-30 kW Horizontal Axis Wind Turbine

GREEF Horizontal Axis Wind Turbine (Power Range: 1KW-30KW)‌ is a cutting-edge clean energy device that efficiently converts wind energy into mechanical energy and then into electrical energy via a generator. Featuring a horizontal-axis design and an intelligent speed-regulation system, it operates effectively in a wide wind speed range of 3–25 m/s and can achieve stable performance in areas with an average annual wind speed of just 4 m/s or higher.

The system consists of ‌aerospace-grade aluminum alloy blades, a permanent magnet generator, and an intelligent controller‌, achieving a conversion efficiency of up to ‌42%‌. Its ‌low-wind-speed startup technology (3 m/s) and hydraulic yaw system‌ ensure continuous power generation even in challenging wind conditions. The turbine supports ‌both off-grid and grid-connected operation‌: it can directly charge battery banks or, through an inverter, supply stable ‌220V/380V AC power‌, meeting diverse electrical needs such as lighting, television, communication equipment, and power tools.

product details

Compared to traditional vertical-axis turbines, this model offers three key advantages:

Zero-emission operation‌ with no fuel consumption, fully compliant with carbon-neutral standards.

Ultra-low noise levels‌ of just ‌45 dB‌, making it suitable for residential installations.

Modular design‌ allowing flexible power scaling from ‌1KW to 30KW‌ to meet varying demands.

Ideal for remote areas without grid access, island communities, and industrial sites with unstable power supply, this turbine delivers ‌1.3 times the annual energy output‌ of comparable models.
