SINEXCEL has announced that its Sirius 135K C&I PCS has achieved UL 1741 and IEEE 1547 certification, meeting the stringent North American standards for safety, grid interconnection and performance, a milestone providing a key pathway for broader deployment across the region.
The product already holds major international approvals for regions including Europe, Australia and Thailand, reinforcing the company’s ability to deliver globally compliant, high-performance energy storage solutions that support the worldwide energy transition.
UL 1741 and IEEE 1547 represent rigorous benchmarks covering electrical safety, mechanical integrity, grid-support functions and system reliability, the Sirius 135K demonstrating strong grid compatibility, load adaptability and environmental resilience during testing and confirming its readiness for demanding North American applications.
Among its core advantages are its global certifications, enabling rapid, streamlined deployment worldwide and its >98% full-load efficiency and 100% unbalanced load handling. Harmonic adaptability of up to 25% also ensures stable power quality across complex industrial grids.
For microgrids and off-grid islands, the product’s proprietary communication and Virtual Synchronous Generator (VSG) control supports seamless parallel islanding for 100+ units and enables high-performance “super-hybrid” modes for diesel-battery integration.
Grid-forming capability and fast transfer response are also features which guarantee stable power supply during sudden load changes and peak demand.
Through advanced technology design and operational optimization, the system delivers 100%higher energy density, a 50% smaller footprint, and 10× switching capacity, lowering the total cost of ownership (TCO) while maximizing long-term returns.
SINEXCEL’s modular storage solutions are certified in over 40 countries and deployed across 60+ markets. With 17GWof installed capacity worldwide, the company supports its partners through 10 global service centres across Europe, North America and Asia-Pacific, backed by a 30-minute rapid response and seven-day parts delivery commitment.
