GSL ENERGY R60 Battery Energy Storage System Passing UL9540A

As the global energy storage industry moves towards a larger scale of deployment, the North American market has emerged as a key growth area for energy storage applications. It is driven by increasing renewable energy capacity and rising demand for grid resilience. Concurrently, industry regulatory standards are continuously being elevated, making thermal safety and fire protection compliance critical thresholds for project approval and delivery.

GSL ENERGY recently announced that its R60 Cabinet Battery Energy Storage System has successfully passed the UL9540A Thermal Runaway Fire Propagation Test and Evaluation. This test serves as a fundamental technical basis within the UL9540 framework and is widely adopted by North American building and fire codes, such as NFPA 855 and IFC to assess the thermal runaway propagation risk and fire containment capabilities of energy storage systems. Achieving this certification demonstrates the R60 Series' excellent performance in key dimensions, including thermal runaway suppression, structural protection, and system-level risk control, providing strong technical support for the product's engineering design, fire safety review, and project implementation in North America and other high-standard markets.

High-Voltage Architecture Cabinet BESS Platform: Technical Advantages of the R60

The R60, targeting commercial, industrial, and premium residential energy storage scenarios, establishes a high-voltage platform-based product portfolio with the following core capabilities:

High-Voltage Architecture & Modular Design: Featuring a standardized cabinet design and high-voltage energy pack architecture, it covers the typical 614.4V operational range, supports capacity expansion through multi-cabinet parallel systems, and is compatible with mainstream high-voltage inverters and C&I energy storage systems.

Grade-A LiFePO₄ Cells: High Safety Margin & Long Cycle Life: Utilizes Grade-A Lithium-Iron Phosphate cells, offering superior thermal stability and cycling performance (design life >6,500 cycles), supporting long-term asset operation and reliable investment throughout the life cycle.

Intelligent BMS & Multi-level Protection Mechanisms: Supports cell-level monitoring, precise SOC/SOH management, anomaly warning, and protection strategies, enabling highly reliable operation and remote maintainability.

Industrial-Grade Structure & Environmental Adaptability: The system design ensures stable operation across a wide ambient temperature range (e.g., typical operating intervals: charging 0–55°C, discharging −20–55°C) and incorporates industrial-standard cabinet construction and thermal management mechanisms such as air-cooling.

Leveraging its modular and high-voltage platform design, the R60 can be widely applied in diverse scenarios, including solar-plus-storage integration, peak shaving & load shifting, backup power systems, micro-grids, and distributed energy resource management, enhancing project deployment flexibility and operational economic efficiency.

The Engineering Value and Market Significance of UL9540A

Enhanced System-level Risk Prevention & Control: Validates the product's robust capabilities in thermal propagation suppression and structural safety.

Facilitating Project Approval & Efficient Delivery: In the fire safety and engineering filing processes across many North American regions, UL9540A test reports can significantly improve approval rates and shorten project timelines.

Alignment with Safety-driven Market Trends: Strengthens GSL ENERGY brand credibility and engineering competitiveness in the global energy storage market.

Comprehensive Certification Coverage: Adapted for Global Engineering-grade Applications

The R60 and related models have passed multiple international standards, including:

UL1973 (Battery System Safety & Performance)

IEC 62619 (Industrial Lithium Battery Safety)

CE (EU Safety & Compliance)

Certification covers multiple series specifications from BESS-R20K-R to BESS-R60K-R, accommodating different capacity configurations and system deployment scenarios, further enriching the product platform's application capabilities.

Product Strategy and Technology Roadmap for North America

GSL ENERGY will continue to deepen its product portfolio strategy around evolving safety standards, system platform-based technology development, and overseas engineering delivery capabilities. Anchored in international standard systems like UL, IEC, and CE, it will accelerate the large-scale deployment of energy storage systems in residential, commercial & industrial, and grid-side applications, driving the adoption of higher safety-grade energy storage deployments through technological innovation and engineering practice.
