SINEXCEL‘s flagship utility-scale Power Conversion Systems (PCS), the StellaON 1250K/1575K, have successfully achieved certification to the comprehensive European Common Standards, this critical regulatory milestone officially validating the company’s technical capacity to deliver highly bankable, high-performance energy infrastructure for the rapidly expanding European renewable market.
The three certifications secured are EN 62477 for CE electrical safety, EN 50549 for dynamic grid compliance and EN IEC 61000 for electromagnetic compatibility, collectively guaranteeing that the equipment is fundamentally safe, electronically non-disruptive and capable of actively regulating grid frequencies. The StellaON series has passed each of these stringent standards by relying on a robust suite of advanced innovations, including grid-forming, system flexibility and omni-adaptability technologies.
At the utility-scale, the flagship StellaON 1250K/1575K PCS is engineered to optimize project economics, safety compliance and grid integration complexity. With a focus on lifecycle efficiency and adaptability across diverse environmental, load and grid conditions, it enables stable, high-performance operation in demanding large-scale deployments. Rather than focusing on a single operational metric, this comprehensive engineering approach ensures that project developers can achieve a significantly lower levelized cost of storage (LCOS) while maintaining maximum uptime.
Luke Lu, SINEXCEL Energy Storage Product Line Technical Director, commented: “Securing the CE and EN 50549 certifications is a testament to our relentless pursuit of technology excellence and market responsiveness. As Europe transitions to a decarbonized future, grid operators demand equipment that not only stores energy but actively fortifies grid resilience. Our StellaON PCS is designed exactly for this mission, ensuring full regulatory compliance while maximizing investment returns.”
