SINEXCEL Strengthens Its Energy Storage Ecosystem at Intersolar Europe 2026

In July 2026, SINEXCEL showcased its dedication to the European market at the Intersolar Europe 2026 exhibition by unveiling its StellaON 1250K/1575K power conversion system (PCS). This high-performance system is set to enhance the energy storage capabilities across Europe, directly supporting the region's transition to renewable energy.

Innovations in Energy Storage

The StellaON 1250K/1575K is designed to meet the evolving needs of the European energy storage market. With a focus on environmental resilience, grid adaptability, and lifecycle efficiency, this new PCS is equipped with Infineon's advanced EconoDUAL™3 power modules. The system operates efficiently at full power even at 55 °C, offers grid-forming capabilities, and achieves a charging efficiency of 98.5%. Such features are crucial for scaling up the use of renewable energy sources throughout Europe.

Commitment to Compliance and Cybersecurity

As regulatory compliance becomes increasingly vital for project financing in Europe, SINEXCEL is proactive in solidifying its reputation. Collaborations with leading certification bodies are key to achieving essential European compliance and safety certifications for the StellaON system. In partnership with TÜV SÜD, the company has not only secured important network safety certifications but also entered into a strategic agreement to enhance cybersecurity measures in line with the Cyber Resilience Act (CRA) and the NIS2 Directive.

Additionally, TÜV NORD has officially recognized compliance with Polish network codes for SINEXCEL's 1725 kW PCS, further expanding the company's compliance framework across the continent.

European Service Network Expansion

To bolster the long-term reliability of its projects, SINEXCEL is expanding its localized service network throughout Europe. This initiative focuses on enhancing capabilities for maintenance, spare parts, and rapid response interventions. A partnership with Eco Service GmbH, which operates in more than twelve countries with a parts center in Germany, ensures comprehensive maintenance and service across Europe. Furthermore, dedicated maintenance operations are being established in Slovakia and Germany through an additional agreement with Sagacity International HK Limited.

Strategic Project Partnerships

To facilitate the execution of large-scale energy storage projects, SINEXCEL has broadened its operational scope. A landmark agreement with Tesla Energy Holding, a Czech manufacturer and integrator of battery energy storage systems (BESS), marks a significant milestone in the implementation of expansive BESS projects. Collaborations with InterConti Trading and Nota Energy will also integrate SINEXCEL's high-efficiency PCS into advanced system solutions.

These partnerships create a robust pan-European ecosystem that promises support throughout the project lifecycle.
