Introduction to Sirius 135K at Intersolar Europe 2025

SINEXCEL has unveiled its latest energy storage solution, the Sirius 135K, aimed at commercial and industrial use, during Intersolar Europe 2025. Addressing significant challenges faced by the energy storage sector, including limited adaptability and low returns on investment, the Sirius 135K represents a new benchmark in energy storage technology. Its design philosophy is not only about meeting current market demands but also about preparing for future energy needs across the globe.

Key Challenges in Energy Storage

Traditionally, commercial and industrial energy storage systems have struggled with two primary issues: inadequate adaptability to changing grid conditions and low efficiency leading to reduced project profitability. The Sirius 135K overcomes these hurdles by utilizing advanced technologies that enhance performance and integration capability.

Unmatched Global Flexibility

Built to accommodate a variety of grid voltages, the Sirius 135K supports AC voltages of 208 V and 400 V to 480 V, complying with various global safety and efficiency standards such as UL, IEC, and VDE. This compliance ensures that installations are quicker and reduces research and development costs by up to 25%. The versatility of this model allows it to be effectively utilized in different regions including North America, Europe, and Southeast Asia, making it an optimal choice for global operations.

Robust Design for Diverse Environments

Sirius 135K is engineered to thrive under demanding conditions and is capable of managing a full range of DC voltages with over 98% efficiency. This represents a notable improvement of 1% over conventional power conversion systems. Thanks to its 3-phase 4-wire topology, the system ensures precise control over reactive and active power, making it ideal for industrial parks that experience high loads.

In environments with weak grids, the Sirius leverages unique impedance and synchronization algorithms that provide reliable grid connections, even in the presence of harmonics up to 25%. Laboratory trials have demonstrated the ability of over 100 parallel PCS units to operate without connection to the grid, utilizing SINEXCEL's proprietary communication protocol. This capability not only facilitates the creation of microgrids but also enhances resilience in off-grid scenarios.

Enhancing Sustainability and Cost Efficiency

For off-grid islands, the Sirius 135K offers hybrid operational modes combining diesel generators with battery energy storage systems (BESS). This hybrid approach promotes fuel savings, reduces operating costs, and minimizes emissions.

Moreover, Sirius ensures a stable power supply during significant events through seamless grid integration, allowing for swift transitions in response to sudden voltage surges. Designed to perform in extreme temperatures of up to 50°C and generate noise levels of just 65 dB, this unit holds an IP65 rating, making it suitable for ports and saline environments, with minimal maintenance requirements.

Lifecycle Advantages and Cost Savings

The Sirius 135K capitalizes on Silicon Carbide (SiC) power devices, an optimized magnetic design, and transformer-less architecture to achieve double the energy density, which translates into considerable cost savings. Additionally, the integration of Schneider cells enhances the circuit breaker's interruption capacity over 10 times, improving both safety and system efficiency.

Broader Applications Beyond Industrial Storage

In addition to the Sirius 135K, SINEXCEL has introduced utility solutions ranging from 450 kW PCS units to 10 MW integrated medium-voltage containers. This expansion reflects SINEXCEL's commitment to comprehensive solutions across diverse applications, including advancements in artificial intelligence data centers (AIDC) and logistics stations, positioning the company as a forward-thinking leader in the electrification landscape.

Conclusion

The launch of the Sirius 135K at Intersolar Europe 2025 marks a significant milestone in the development of energy storage solutions. With its innovative design and robust performance, this system is poised to transform how commercial and industrial sectors manage energy, contributing significantly to global sustainability and operational efficiency. As the energy sector continues to evolve, products like the Sirius 135K will play a crucial role in shaping a more reliable and eco-friendly energy future.
