SHENZHEN, China, Feb. 10, 2026 /PRNewswire/ -- SINEXCEL (300693.SZ) announced that its commercial & industrial (C&I) PCS (power conversion system), the Sirius 135K, has achieved UL 1741 and IEEE 1547 certification, meeting stringent North American standards for safety, grid interconnection, and performance. This milestone clears a key pathway for broader deployment across the region.

SINEXCEL Sirius 135K PCS earns UL 1741 & IEEE 1547 Dual Certification, Advancing North American Market Entry

The Sirius 135K already holds major international approvals, including EN 62477, EN 50549, EN 61000 (Europe), AS 4777.2 (Australia), and PEA & MEA (Thailand), reinforcing SINEXCEL's ability to deliver globally compliant, high-performance energy storage solutions that support the worldwide energy transition.

Dual Certification Demonstrates Proven Performance

UL 1741 and IEEE 1547 represent rigorous benchmarks covering electrical safety, mechanical integrity, grid-support functions, and system reliability. The Sirius 135K demonstrated strong grid compatibility, load adaptability, and environmental resilience, confirming its readiness for demanding North American applications.

Three Core Advantages for C&I Storage - Unleashing Value Across the Lifecycle

Engineered to address complex interconnection requirements, harsh environments, and return-on-investment pressures, the Sirius 135K focuses on global compatibility, scenario adaptability, and lifecycle value.

  • Global-ready: Supports major regional voltage standards and certifications, enabling fast, streamlined deployment worldwide.
  • Scenario-ready:
    • Energy-intensive industrial parks: Delivers >98% full-load efficiency and 100% unbalanced load handling. Harmonic adaptability of up to 25% ensures stable power quality across complex industrial grids.
    • Microgrids/ Off-grid islands: Featuring proprietary communication and Virtual Synchronous Generator (VSG) control, it supports seamless parallel islanding for 100+ units and enables high-performance "super-hybrid" modes for diesel-battery integration.
    • Large-scale events: Grid-forming capability and fast transfer response ensure stable power supply during sudden load changes and peak demand.
    • Extreme environments: With IP66 protection and C5 corrosion resistance, the unit maintains continuous operation without derating at 55°C, mastering high-temperature, high-altitude, and high-humidity climates.
  • Lifecycle-ready:Through advanced technology design and operational optimization, the system delivers 100% higher energy density, a 50% smaller footprint, and 10× switching capacity, lowering total cost of ownership (TCO) while maximizing long-term returns.
