en.Wedoany.com Reported - Sungrow, a global leading supplier of photovoltaic inverters and energy storage systems, has achieved new progress in grid-forming technology. Its SC210HX series Power Conversion System (PCS) has obtained VDE FNN prototype certification from TÜV Rheinland in Germany, becoming the world's first energy storage PCS to pass the full set of German medium and high voltage grid connection standards and grid-forming performance verification.
This certification enables the PowerTitan energy storage system equipped with the SC210HX PCS series to significantly shorten grid connection time, reduce project acceptance risks, accelerate entry into Europe's latest inertia market, and substantially enhance the investment and financing competitiveness of energy storage projects. The certification framework, developed by VDE FNN (the German standard for grid technology and operation), sets comprehensive requirements for medium and high voltage grid connection. Widely recognized by European grid operators, developers, and financial institutions, this certification serves as a key benchmark for evaluating the compliance, reliability, and grid support capability of energy storage projects.
Utilizing Sungrow's self-developed Stem-Cell Grid-Forming Technology, the energy storage system equipped with the SC210CX series PCS demonstrates exceptional grid adaptability and stable grid support capabilities. The system can independently absorb or output active and reactive power, supporting full-scenario grid requirements such as frequency regulation, voltage regulation, and backup power support. In weak grids with high renewable energy penetration, the converter maintains voltage source characteristics and rapidly outputs dynamic reactive current during grid short-circuit faults. The system can establish a grid without external synchronization, supporting black start and island operation, effectively addressing grid connection challenges for remote energy storage stations and off-grid projects in Europe.
By successfully completing the rigorous VDE FNN testing process, Sungrow has verified that its hardware reliability, proprietary control algorithms, and grid-forming performance fully comply with Germany's strictest mandatory grid standards. This certification is an authoritative recognition of Sungrow's technological leadership in advanced energy storage and grid support solutions. It also brings tangible commercial value to project developers. With increasingly stringent European market standards, leading investment institutions and lending banks regard TÜV Rheinland VDE certification as a core indicator for evaluating project compliance and equipment reliability. This certification enables developers to significantly shorten grid connection time, avoid project delays during acceptance, and comply with Europe's latest inertia energy storage access rules. Furthermore, it enhances the credibility, bankability, asset value, and financing prospects of energy storage projects.
With its full range of VDE-compliant grid-forming energy storage products, Sungrow will continue to deepen its professional capabilities in Europe's energy transition, providing global customers with safer, more user-friendly, and high-yield energy storage solutions.
