Intelligent advancement
of proven technology
The new ENERCON 4 MW platform combines innovative
technology and intelligent modular design for more efficiency and reliability. Systematic, continued development of tried-and-tested components, increased use
of equal parts and standardisation of components are
key features of the new platform concept and give birth
to a new wind energy converter design that meets the
highest quality standards.
