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

Excellent Power Quality

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

Higher Efficiency

The efficiency is as high as 98% under rated conditions, greatly increasing the turbine’s power generation revenue

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

Efficient O&M

Modular, lightweight, and standardized component design simplifies assembly and maintenance, reducing material and spare parts costs

Energy-saving Standby Mode

The energy-saving standby mode reduces losses during standby periods for both the converter and liquid cooling system, enhancing the owner's power generation revenue

Remote Monitoring and Intelligent Diagnosis

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