SINEXCEL’s flagship utility-scale Power Conversion System (PCS), the StellaON 1250K/1575K, has been granted Poland grid certification by TÜV SÜD, with compliance confirmed against RfG:2016, NC RfG:2025 and PTPiREE:2024. The company has also completed official PTPiREE listing, making it 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 covering 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.
