Just because they are small wind turbines, no sacrifices can be made in safety and performance. You need to demonstrate your design’s proof of quality to customers and regulators, as well as for your own satisfaction.

We help you increase the technical integrity, structural reliability, functionality and safety of your product. Our certification process ensures that your wind turbine design complies with the relevant standards and guidelines. We tailor our support to match your specific needs, including your geographic plans for product distribution.

The common standard for small wind turbines is IEC 61400-2. Applicable to wind turbines with a rotor swept area smaller than 200 m2 that generate a voltage below 1000 VAC or 1500 VDC.

The certification process

Product assessment includes aspects such as functionality, safety, and integrity in relation to:

  • Load assumptions
  • Safety system and manuals
  • Rotor blades
  • Machinery components
  • Tower
  • Foundation
  • Electrical installations
  • Testing
  • Commissioning

The results of all successful technical assessments related to a wind turbine are documented in Certification Reports and a concluding Statement of Compliance.
