Sungrow Achieves World's First 'Passport' for German Inertia Market Through VDE FNN Prototype Certification

Sungrow's Historic Achievement in the German Energy Sector

Introduction

Sungrow, a leading global provider of photovoltaic inverters and energy storage systems, has accomplished a remarkable milestone in the field of grid-forming technology. The company has become the first in the world to receive a 'passport' for the German inertia market, thanks to its SC210HX power conversion systems (PCS) achieving the VDE FNN prototype certification.

VDE FNN Certification Explained

The certification, awarded by TÜV Rheinland, confirms that Sungrow's PCS meets all German standards for connecting to medium and high voltage grids, while also undergoing a rigorous performance verification process. The VDE FNN is renowned for establishing comprehensive requirements for integration into electricity networks, which is essential for ensuring the reliability and compliance of energy storage projects.

Benefits of VDE FNN Certification

Sungrow's PowerTitan energy storage systems, equipped with the SC210CX PCS, will benefit significantly from this certification. The technology allows for reduced grid connection times and minimizes project validation risks. As a result, it expedites entry into the emerging European inertia market and enhances the investment competitiveness of energy storage projects. This is especially timely, given the increasing demand for reliable energy solutions in Europe.

Advanced Technology

A highlight of Sungrow’s offering is its 'Stem-Cell Grid-Forming' technology. This internally developed system allows energy storage units to adapt flexibly to network conditions, providing stable support to the grid. It autonomously absorbs or injects active and reactive power, responding adeptly to different scenarios, such as frequency regulation and emergency power supply. The system remains effective even in fragile grids dominated by renewable energy sources, maintaining voltage source characteristics and delivering rapid reactive current in case of short-circuit faults.

Energy Transition Support

Another groundbreaking feature is the ability to establish a power network without relying on external synchronization. This capability supports autonomous start-up and island operation, which is critical for tackling grid connection challenges in remote European regions. Sungrow’s achievement of the VDE FNN certification underscores the reliability of its hardware, proprietary control algorithms, and network support performance.

Commercial Value

Beyond its technical significance, the VDE FNN certification adds tangible commercial value for project developers. As European market standards continue to strengthen, financial institutions and investors increasingly recognize TÜV Rheinland VDE certification as a key criterion for assessing project compliance and equipment reliability. This compliance facilitates faster grid connections, mitigates project delays during acceptance phases, and adheres to the latest European regulations regarding energy storage for inertia.

Conclusion

With this certification, Sungrow not only strengthens its position as a technical leader in advanced energy storage solutions but also enhances the credibility and attractiveness of its projects in the investment landscape. The company plans to leverage its comprehensive range of energy storage products, all compliant with VDE standards, to deepen its expertise in Europe’s energy transition and provide safer, grid-friendly, and efficient energy storage solutions to clients worldwide.

By achieving this landmark certification, Sungrow is set to advance its commitment to powering a sustainable energy future. As Europe continues to prioritize energy resilience, Sungrow’s innovations will likely play a pivotal role in supporting the continent's energy demands.
