SINEXCEL Expands European Energy Storage Ecosystem

MUNICH, July 6, 2026 - SINEXCEL, a major player in the energy sector, showcased its commitment to enhancing the European energy landscape at Intersolar Europe 2026. The event served as a platform for the launch of their latest utility-scale Power Conversion System (PCS), the StellaON 1250K/1575K, which integrates state-of-the-art Infineon devices. This move is expected to significantly bolster its presence in the market while aligning with the growing energy demands of Europe.

Addressing Evolving Energy Storage Needs

The newest product, StellaON 1250K/1575K, has been meticulously designed to cater to the evolving energy storage market in Europe. It specifically targets the industry's increasing needs for improved environmental resilience, adaptability to various grid conditions, and optimization of lifecycle efficiency. Featuring Infineon’s advanced EconoDUAL™3 power modules, the system allows for full power operation at up to 55°C temperatures, possesses grid-forming capabilities, and achieves an impressive 98.5% efficiency at full load, making it suitable for utility-scale applications and assisting in Europe's transition to renewable energy sources.

Strengthening Compliance and Cybersecurity

In response to regulatory pressures that are increasingly tied to project financing, SINEXCEL is stepping up its compliance efforts. They have strengthened their collaborations with leading certification bodies, including a strategic partnership with TÜV SÜD. This collaboration has led StellaON to secure essential European grid and safety certifications. Moreover, both entities have signed a significant agreement to advance their cybersecurity measures, anticipating compliance with the forthcoming EU Cyber Resilience Act (CRA) and NIS2 requirements.

Furthering its compliance coverage, SINEXCEL also received Polish grid code compliance certification for its 1725kW PCS model from TÜV NORD, enhancing its foothold within the European market significantly.

Building a Comprehensive Service Network

To ensure lasting reliability for its energy solutions, SINEXCEL is expanding its localized service operations throughout Europe. This initiative is focused on enhancing maintenance, spare parts availability, and swift response capabilities across the continent. The company's partnership with Eco Service GmbH – a technical service provider operating in over twelve countries, complete with a spare parts centralized hub in Germany – guarantees comprehensive support for maintenance across Europe.

Additionally, SINEXCEL has collaborated with Sagacity International Hk Limited, establishing dedicated maintenance services in Slovakia and Germany. These strategic partnerships are designed to ensure a seamless operational delivery for utility-scale energy projects.

Strategic Collaborations for Project Execution

To further broaden its operational execution capabilities, SINEXCEL has inked a notable partnership with Tesla Energy Holding in the Czech Republic, focusing on executing large-scale Battery Energy Storage System (BESS) projects. Additionally, strategic alliances with companies like InterConti Trading s.r.o. and Nota Energy will enhance integration of SINEXCEL's high-efficiency PCS within advanced systems.

These collaborative ventures are anticipated to create a robust end-to-end lifecycle support framework across Europe, thereby reinforcing SINEXCEL's position as a pivotal partner in promoting sustainable energy solutions.
