Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Versatile Wind Energy Generation: Captures wind energy from any direction via vertical-axis design, eliminating the need for orientation adjustments.
  • Scalable Power Output: Offers capacities from 200W to 5kW, supporting residential, commercial, and industrial energy needs.
  • Low Wind Speed Efficiency: Starts generating power at just 2.5m/s, ideal for areas with moderate or variable wind conditions.

Key features

  • 1. Material Technology

    • With lightweight composite blades, reduce weight and enhance efficiency compared to traditional models*. The turbine’s design uses materials like aluminum or composites to minimize stress on components and optimize energy capture.

  • 2. Interactive Design

    • With a vertical-axis design, capture wind from any direction without reorientation, ideal for variable wind environments*. Unlike horizontal-axis turbines, this model eliminates the need for complex alignment mechanisms.

  • 3. Performance Parameters

    • With a low start-up wind speed of 2.5 m/s, generate power in mild breeze conditions, outperforming conventional turbines*. Its permanent magnet generator ensures stable output across voltages (48V/220V/380V) for diverse applications.

  • 4. Scenario Solutions

    • With compact size and rooftop compatibility, install in limited spaces like residential or commercial areas where traditional turbines can’t fit*. The 200W–5kW capacity range adapts to small-scale energy needs, from homes to small businesses.

  • 5. Certification Standards

    • With CE and EPR Germany certifications, ensure compliance with safety and environmental standards, meeting rigorous international regulations*. These certifications validate reliability and sustainability for global use.
