SINEXCEL’s flagship utility-scale Power Conversion System (PCS), the StellaON 1250K/1575K, has successfully obtained Poland Grid certification from TÜV SÜD, with compliance confirmed against RfG:2016, NC RfG:2025, and PTPiREE:2024. The company has also completed official PTPiREE listing, making SINEXCEL among the first manufacturers to secure both certification and listing following Poland’s 2025 grid code update.
This certification validates that a power-generating module can operate safely and reliably on the Polish distribution network. The evaluation covers frequency stability, voltage fault ride-through with fast fault current injection, post-fault active power recovery, remote active power control, and reactive power capability. The StellaON series passed all test items with positive results across Type B, C, and D module categories. With PTPiREE listing now also in place, the products are fully qualified to serve Polish developers and grid operators, adding to a growing portfolio of European market approvals.
The StellaON series is SINEXCEL’s latest utility-scale PCS, built to maximize project economics through grid-forming, system flexibility, and omni-adaptability technologies. With a focus on lifecycle efficiency and adaptability across diverse environmental, load, and grid conditions, the StellaON 1250K/1575K maintains full rated power performance under 55°C, avoiding the efficiency losses and accelerated degradation that conventional equipment suffers in demanding climates. This comprehensive engineering approach enables a significantly lower levelized cost of storage (LCOS) while ensuring maximum uptime across large-scale deployments.
The StellaON series is already proven in the field, having achieved grid connection in Vietnam as part of a 2.5 MW/5 MWh BESS project for Vietnam Electricity Group (EVN). Combined with European certifications including EN 62477, EN 50549, and EN IEC 61000, the Polish Grid approval further solidifies SINEXCEL’s position as a fully certified partner for global energy storage infrastructure.
With solutions deployed in over 60 markets and a cumulative installed capacity exceeding 17 GW, SINEXCEL remains committed to providing secure, high-performance, and fully compliant energy storage solutions that support the global energy transition.
Founded in 2007, SINEXCEL is a pioneer in energy storage, EV charging, and power quality solutions. With 17 GW of installed storage, 200,000 EV DC chargers, and nearly 20 million amperes of Active Harmonic Filter deployed, SINEXCEL partners with industry leaders to empower energy freedom.
