SINEXCEL Expands European Energy Storage Ecosystem at Intersolar Europe 2026

In a significant development for the renewable energy sector, SINEXCEL, a leader in energy storage solutions, has reinforced its long-term commitment to Europe by unveiling its latest utility-scale power conversion system (PCS) at Intersolar Europe 2026. The new system, named StellaON 1250K/1575K, integrates advanced technology and establishes strategic partnerships aimed at enhancing energy storage capabilities across Europe.

Enhancing the Energy Storage Landscape

The StellaON 1250K/1575K was specifically designed to meet the evolving demands of the European energy market, focusing on sustainability, adaptability to grids, and lifecycle efficiency. The PCS incorporates the cutting-edge EconoDUAL™3 power modules from Infineon, allowing it to operate at full capacity even at temperatures reaching 55°C. This system boasts an impressive full-load efficiency of 98.5%, supporting Europe’s transition towards high renewable energy sources.

Commitment to Compliance and Cybersecurity

As regulatory compliance becomes increasingly essential for project funding in Europe, SINEXCEL is proactively working alongside major certification bodies. The StellaON system has obtained critical energy system and safety certifications through collaboration with TÜV SÜD, reinforcing SINEXCEL's commitment to regulatory adherence. Moreover, the strategic agreement with TÜV SÜD will enhance cybersecurity protocols in accordance with the EU’s Cyber Resilience Act (CRA) and NIS2 directives.

Additionally, TÜV NORD has granted compliance certification for SINEXCEL's 1725 kW PCS according to national grid codes in Poland, broadening the company’s compliance outreach throughout Europe.

Building a Supportive Ecosystem

To ensure the long-term reliability of its projects, SINEXCEL is expanding its localized service ecosystem across Europe. This initiative includes improving maintenance capabilities, establishing spare parts availability, and enhancing rapid response services. Through a partnership with Eco Service GmbH, which operates in over twelve countries and is based in Germany, SINEXCEL is set to ensure comprehensive technical support throughout the continent.

Furthermore, a partnership with Sagacity International HK Limited will facilitate specialized maintenance operations in Slovakia and Germany. This strategic approach not only enhances service availability but also signifies SINEXCEL’s enhanced operational capacity.

Strategic Collaborations for Future Growth

To push forward its utility-scale Battery Energy Storage Systems (BESS) projects, SINEXCEL has entered into a landmark agreement with Tesla Energy Holding, a Czech assembly plant and BESS integrator. This collaboration aims to leverage Tesla's expertise in energy storage to realize large-scale projects effectively. Additionally, strategic partnerships with InterConti Trading s.r.o. and Nota Energy will fuse SINEXCEL's efficient PCS with advanced system integration.

These collective efforts are set to form a pan-European ecosystem that supports comprehensive lifecycle management for energy storage systems, bolstering the transition towards cleaner energy.
