SINEXCEL has launched its StellaON 1250K/1575K PCS at the 2026 edition of Intersolar Europe in Munich, integrating Infineon devices to address the continent’s evolving demands for environmental resilience, grid stability and lifecycle economics, maximizing energy value through omni-adaptability.
Built around the concept of ‘Omni-Adaptability’, StellaON is engineered to perform reliably across harsh environments, demanding grids and large-scale applications.
Powered by Infineon’s EconoDUAL™3 modules with low thermal resistance, the StellaON 1250K/1575K delivers continuous, uncompromised output at 55°C—10°C above the industry average, eliminating 15%-20% power derating while reducing oversizing costs by up to 20%.
Engineered with anIP65 enclosure and C5 anti-corrosion rating, it operates flawlessly in extreme climates while maintaining noise levels as low as 65 dBfor strict European urban permitting.
To support Europe’s evolving grid requirements, including NC RfG 2.0, StellaON features grid-forming capability with PQ, VF, VSG and SVG modes, supports 1.5x overload for 60s (vs. 1.2x industry average), delivers GW-scale grid-forming performance and black-start capability and enables four AC/DC unitsto operate in parallel, providing greater scalability, redundancy and grid resilience for large-scale deployments.
StellaON achieves a98.5% maximum full-load efficiency and a 0.6% round-trip efficiency gain, substantially lowering the Levelized Cost of Storage (LCOS).
Its modular configurations span 1- to 8-hour durations, scaling seamlessly from 20ft 2.5MW to 40ft 12.5MWMV stations.
For O&M, an innovative self-cleaning design reduces lifetime OpEx by 15%. It features a Mean Time Between Failures (MTBF) exceeding 300,000 hours, ensuring99% uptime, with key component replacement in under one hour and full PCS replacement in less than two hours.
Following a successful grid connection in Vietnam in March, where it demonstrated reliable operation under extreme heat and humidity, StellaON has secured more than 500 MW oforders in 1H 2026, with over 15 projects currently under deployment across Europe, Asia-Pacific and Africa.
The solution is compliant with the grid codes of Germany, Poland, the Netherlands, Belgium and Romania, with Spain and U.S. certifications coming soon.
