Hopewind PV Products-Hopewind

Hopewind has over 10 years of experience in the development and application of three-level systems, along with a mature supply chain. The product shares many similarities with the 690V system

Platform-Based Design

The product is built on the 690V system platform, featuring a uniform structural layout and cabling design. This ensures a seamless transition in turbine upgrading design

Excellent Power Quality

The converter uses a three-level topology solution, with more output levels and lower harmonic content

Lower Conversion losses

Reduced current due to voltage decreases lowers the heat generated by the converter, thereby reducing the cooling demands on the tower

Better Cost-Effectiveness

With generator power design bottlenecks addressed and internal cable usage reduced within the turbine, the overall cost of the turbine system is lowered

Remote Monitoring and Intelligent Diagnosis

The remote network system of the converter can intelligently diagnose wind turbine faults
