Expanding Energy Storage Capabilities in Europe

At the recent Intersolar Europe 2026, SINEXCEL showcased its dedication to the European renewable energy market by introducing the new StellaON 1250K/1575K Power Conversion System (PCS) designed specifically for large installations. This state-of-the-art system is equipped with Infineon's advanced components, aiming to meet the increasing demands for environmental sustainability, grid adaptability, and lifecycle efficiency in energy storage. The introduction of this innovative PCS represents a critical step toward accelerating the deployment of large-scale energy storage solutions across Europe, enabling a smooth transition to high renewable energy integration in power systems.

Key Features of the StellaON 1250K/1575K

The StellaON system integrates Infineon’s EconoDUAL™3 power modules which allow full load operation at 55°C. It offers grid-forming capability and achieves a remarkable full-load efficiency of 98.5%—further supporting Europe's ambitious renewable energy targets. Designed to address the region’s evolving energy landscape, the StellaON solution ensures compliance with stringent European regulations while enhancing cybersecurity features, which have become critical in the face of new legislative requirements.

Strengthening Compliance and Cybersecurity

With the increasing complexity of regulatory landscapes in Europe, SINEXCEL is proactively enhancing its compliance framework. Collaborating with notable certification bodies like TÜV SÜD, SINEXCEL has successfully acquired essential European grid and safety certifications for the StellaON product line. Moreover, a strategic agreement with TÜV SÜD was made to promote cybersecurity measures aligned with the EU Cyber-Resilience Act (CRA) and the NIS2 Directive. Additionally, TÜV NORD has awarded SINEXCEL's 1,725 kW PCS with certification for conformity to Polish grid regulations, thus broadening SINEXCEL’s compliance coverage throughout Europe.

Establishing a Pan-European Service Network

To ensure project reliability and longevity, SINEXCEL is expanding its localized service ecosystem. This involves enhancing maintenance, supply chain logistics for spare parts, and emergency responsiveness across the continent. A partnership with Eco Service GmbH, a provider of on-site technical services in over a dozen countries with a spare parts center in Germany, ensures comprehensive support. Furthermore, dedicated maintenance hubs are being established in Slovakia and Germany through collaboration with Sagacity International.

Enhancing Project Execution Capacities

In terms of project implementation, SINEXCEL is increasing its operational capabilities and has signed a landmark agreement with Tesla Energy Holding, a Czech-based assembly and integration company specializing in Battery Energy Storage Systems (BESS). Additionally, strategic alliances with companies like InterConti Trading s.r.o. and Nota Energy will connect SINEXCEL's highly efficient power conversion systems with advanced system integration technologies.

Together, these initiatives create a robust pan-European ecosystem that provides seamless support throughout the energy storage lifecycle.
