Introducing the SINEXCEL Sirius 135K Energy Storage Solution at Intersolar Europe 2025
SINEXCEL Sirius 135K: A Game-Changing Energy Storage Solution
At the prestigious Intersolar Europe 2025 exhibition, SINEXCEL has unveiled its latest energy storage solution, the Sirius 135K, specifically designed for commercial and industrial uses. With a capacity of 1,000 Vdc, this innovative system is engineered to tackle several pressing challenges faced by the energy sector today.
Addressing Key Challenges
The energy storage market, particularly for commercial and industrial scenarios, often grapples with two main issues: poor adaptability to local conditions and low return on investment (ROI). Traditional systems frequently encounter complications such as difficulty connecting to the grid, complex load requirements, and harsh environmental conditions. Moreover, the high initial costs and fluctuating efficiency of existing solutions can significantly hinder project profitability.
The Sirius 135K aims to turn these challenges into opportunities. Embracing a design philosophy centered on global readiness, scenario-appropriate responses, and lifecycle resilience, this product intends to deliver lasting value to its users. It promises to unlock energy potential throughout its operational lifespan.
Global Compatibility
One of the standout features of the Sirius 135K is its global readiness. Supporting a range of network voltages from 208 V, 400 V, to 480 V in a 3-phase 4-wire (3P4W) AC format allows it to meet various international certification requirements, including UL, IEC, EN, JET, and VDE. This versatility facilitates faster deployment and can reduce research, development, and integration costs by up to 25%. Essentially, a single model can cater to multiple regions, including North America, Europe, and Southeast Asia.
Design for Harsh Environments
Additionally, the Sirius 135K has been designed to withstand demanding workloads and extreme conditions. Its ability to handle a full DC voltage range with over 98% efficiency - outperforming traditional PCS solutions by 1% - ensures it meets high performance standards. Its unique 3P4W topology allows precise management of active and reactive loads while providing 100% support for unbalanced loads, making it ideal for high-demand industrial parks.
For areas with weak grids, the Sirius 135K utilizes virtual impedance algorithms and synchronization to maintain a reliable grid connection even at 25% harmonic distortion levels. Lab tests conducted on over 100 units have demonstrated its effectiveness in operating in parallel off-grid via SINEXCEL's proprietary communication protocol, paving the way for true microgrid setups. In off-grid locations, the system enhances fuel savings and cuts costs by supporting a hybrid “Diesel + BESS” mode, notably minimizing emissions and stabilizing power during major events via seamless grid forming and rapid transfer capabilities.
Longevity and Cost-effectiveness
When it comes to durability, the Sirius 135K is built to last, withstanding ambient temperature extremes of up to 50 °C—11% more than standard industrial units—and generating a noise level of just 65 dB. With an IP65 rating and C5 protection, it’s well-suited for challenging environments like ports and islands requiring minimal maintenance.
The device employs SiC power devices paired with an optimized magnetic design and a transformer-less architecture, significantly increasing energy density while saving costs. An integrated Schneider switchgear improves switch disconnection capacity more than tenfold, thereby enhancing safety and efficiency.
Beyond Commercial Applications
But SINEXCEL's innovations do not stop at the Sirius 135K. The company has also introduced solutions for utilities ranging from 450kW PCS to a 10 MW integrated medium-voltage container, alongside groundbreaking applications like AI-driven data centers and low-altitude logistical stations, showcasing its commitment to an electrified future.
The Sirius 135K emerges as a groundbreaking solution poised to redefine energy storage in commercial and industrial environments, emphasizing not just adaptability and sustainability but also robust performance across diverse global contexts.
