SINEXCEL has taken part in the 2025 edition of Intersolar Europe in Munich, showcasing its comprehensive portfolio of solutions. At the core of the company’s presence this year was the launch of its 1000Vdc C&I storage solution, Sirius 135K.
With C&I storage commonly facing the two major challenges of poor adaptability (grid connection difficulties, complex loads and harsh environments) and low return on investment, with high upfront costs and fluctuating efficiency severely impacting project profitability, the Sirius 135K offers a global-ready, scenario-ready and lifecycle-ready solution designed to overcome these obstacles and unlock long-term value for customers.
The product supports grid voltages from 208V, 400V to 480V 3P4W AC and meets global certification requirements including UL, IEC, EN, JET and VDE, enabling faster rollouts and reducing R&D and integration costs by up to 25%.
A single model can serve multiple regions, including North America, Europe and Southeast Asia.
Sirius accommodates a full DC voltage range with >98%PCS efficiency – a 1% improvement over traditional PCS solutions – and its true 3P4W topology enables precise active/reactive control and 100% unbalanced load support – ideal for high-load industrial parks.
For weak grids, Sirius uses virtual impedance and synchronization algorithms to ensure reliable grid connection even with 25% harmonics. In lab-proven tests, over 100 PCS units can operate off-grid in parallel via SINEXCEL’s proprietary communication protocol, enabling real microgrids.
In off-grid islands, with proven performance working with various generators, Sirius supports a “Diesel + BESS hybrid mode” to achieve fuel savings, cost reduction, and emission cuts.
It also ensures stable power for large events via seamless grid-forming and fast transfer to tackle sudden power surges.
Built to withstand50°C ambient temperatures non-debating (11% above the industry standard) and 65dB noise level, Sirius features IP65 and C5 protection – ideal for ports, islands and high-salinity environments with minimal maintenance needs.
Sirius leverages SiC power devices, optimized magnetic design, and a transformerless architecture to double energy density and savecosts. Integrated Schneider switchgear enhances switch breaking capability by over 10×, improving system safety and efficiency.
During the Munich event, SINEXCEL also showcased utilitysolutionsfrom 450kW PCS to 10MW, an integrated MV container and two application breakthroughs in an AIDC (AI Data Center) and low-altitude logistics station, underlining its full-stack capabilities.
