SINEXCEL Expands European Energy Storage Ecosystem

At the recent Intersolar Europe 2026 event, SINEXCEL (300693.SZ) reaffirmed its long-term commitment to the European energy market by introducing its large-scale energy conversion system, the StellaON 1250K/1575K. This innovative system integrates advanced Infineon devices and aims to strengthen local regulatory compliance, service operations, and project execution capabilities across Europe. These developments are part of SINEXCEL’s strategy to enhance its European energy storage ecosystem and facilitate the acceleration of large-scale storage systems.

Next-Generation Large-Scale Energy Storage

The StellaON 1250K/1575K has been meticulously designed to cater to the evolving European energy storage market. It addresses the increasing demands for environmental resilience, grid adaptability, and lifecycle efficiency. Featuring Infineon’s EconoDUAL™3 power modules, the system can operate at full power even at temperatures of 55°C. It also boasts a network formation capability and offers a remarkable 98.5% efficiency at full load for large-scale applications, significantly supporting Europe’s transition towards energy systems that heavily rely on renewable sources.

Strengthening Compliance and Cybersecurity Measures

As regulatory compliance has become a critical factor for project financing in Europe, SINEXCEL has been working closely with prominent certification bodies to fortify its standing. The collaboration with TÜV SÜD resulted in StellaON receiving essential European security and grid certifications. Additionally, the two companies formalized a strategic agreement to advance cybersecurity in alignment with the EU Cyber Resilience Act (CRA) and NIS2 requirements. Complementing this, TÜV NORD officially certified compliance with Poland’s grid code for SINEXCEL’s 1725kW PCS, thereby broadening the company's compliance reach throughout Europe.

Building a Pan-European Service Network

To ensure the long-term reliability of its projects, SINEXCEL is expanding its local service ecosystem throughout Europe, enhancing maintenance, spare parts availability, and rapid response capabilities. A partnership with Eco Service GmbH, a technical on-site provider operating in over twelve countries with a spare parts hub in Germany, ensures comprehensive maintenance and storage support across the continent. Furthermore, an additional agreement with Sagacity International Hk Limited will establish specialized maintenance operations in Slovakia and Germany.

In terms of project execution, SINEXCEL has enhanced its operational capacity by signing a strategic agreement with Tesla Energy Holding, a Czech assembler and integrator of battery energy storage systems (BESS), aimed at executing large-scale BESS projects. Strategic alliances with InterConti Trading s.r.o. and Nota Energy will enable the integration of SINEXCEL’s high-efficiency energy storage systems with advanced system integrations. Collectively, these collaborations form a pan-European ecosystem that guarantees comprehensive support throughout the product lifecycle.
