Exploring the Advanced Features of SINEXCEL's Sirius 135K at Intersolar Europe 2025

SINEXCEL Sirius 135K: A Game Changer in Energy Storage

At the recent Intersolar Europe 2025, SINEXCEL unveiled its state-of-the-art energy storage solution, the Sirius 135K. This cutting-edge system is designed to tackle the prevalent challenges faced by commercial and industrial (C&I) storage applications, specifically poor adaptability and low return on investment (ROI). This article delves into the unique features of the Sirius 135K and its potential impact on the global energy storage landscape.

Addressing Key Challenges in C&I Storage

The commercial and industrial sectors often grapple with significant barriers when it comes to energy storage systems. One of the primary issues is the lack of adaptability to different grid conditions and operational demands. Additionally, high upfront costs and inconsistency in efficiency can drastically reduce project profitability. The Sirius 135K was developed with a clear focus on overcoming these obstacles, thereby maximizing value for its users.

Global-Ready Design

One of the standout features of the Sirius 135K is its Global-Ready capability. This system can operate across a wide range of grid voltages, specifically from 208V to 480V AC, fulfilling vital global certification standards like UL, IEC, EN, JET, and VDE. This versatility enables SINEXCEL to streamline deployment processes, accelerating rollout times and cutting research and development costs by up to 25%. By offering a single model that is suitable for various regions, including North America, Europe, and Southeast Asia, the Sirius 135K sets a new standard for ease of integration.

Scenario-Ready Performance

Another remarkable aspect of the Sirius 135K is its Scenario-Ready performance, tailored for demanding operational environments. The system is capable of handling a full DC voltage range with an impressive PCS efficiency exceeding 98%, a 1% improvement over previous systems. Its true 3P4W topology facilitates precise active and reactive power management, offering 100% support for unbalanced loads. This makes it ideal for high-load industrial parks.

In scenarios with weak grids, the Sirius 135K employs advanced virtual impedance and synchronization algorithms, guaranteeing reliable grid connections even amid challenging conditions, such as a 25% harmonic distortion. Extensive lab tests have confirmed that the system can operate off-grid in parallel with over 100 PCS units using SINEXCEL’s proprietary communication protocol, establishing real microgrid functionality.

Furthermore, its design accommodates hybrid operations, combining traditional diesel generators with the battery energy storage system (BESS) to achieve cost savings, lower emissions, and enhanced fuel efficiency. The Sirius 135K also excels in providing stable power during large events through efficient grid-forming capabilities, allowing for swift responses to sudden power surges.

Lifecycle-Ready Philosophy

Sustainability and cost efficiency are critical in today’s energy sector, and the Sirius 135K reflects a Lifecycle-Ready approach, significantly reducing total cost of ownership (TCO). This is achieved through the use of SiC power devices, an optimized magnetic design, and a transformerless architecture that enhances energy density and cost savings.

Additionally, the integrated Schneider switchgear improves switch-breaking capabilities by more than tenfold, thereby elevating both safety and operational efficiency. SINEXCEL's commitment to innovation doesn't stop with the Sirius 135K; they also revealed utility solutions ranging from 450kW PCS to 10MW integrated medium voltage containers, alongside pioneering applications for AI Data Centers (AIDC) and low-altitude logistics stations.

Conclusion

The launch of the Sirius 135K at Intersolar Europe 2025 not only symbolizes SINEXCEL's dedication to addressing the challenges of energy storage but also marks a significant step towards a more electrified and sustainable future. With its innovative features designed to maximize performance and ROI, the Sirius 135K is poised to become a game changer in the C&I energy storage market. Stakeholders from across the globe should keep a close eye on this groundbreaking solution as it gains traction across multiple sectors.
