The Siemens Gamesa 4.X platform leverages the knowledge acquired through the development of our latest onshore wind turbines and integrates innovative technologies to achieve higher efficiency and cost-effectiveness.
Our onshore portfolio relies on proven concepts with extensive track record in the market, such as the combination of a three-stage gearbox (two planetary and one parallel) and a doubly-fed induction generator, which offer the higher levels of reliability.
In addition, the inclusion of an optional premium converter allows us to comply with the most demanding grid connection requirements.
