Recently, Goldwind's GoldBlock L700 series energy storage system has successfully passed the full set of UL9540A tests, receiving the official test report issued by SGS, a globally recognized certification authority. As one of the most critical safety standards in the global energy storage industry, UL9540A serves as a key "passport" for products entering international markets such as North America. This marks the successful completion of full-process testing for the GoldBlock L700 from components to the entire system, creating a strong "moat" of trust around the product series in the global market.

Thermal runaway remains a major vulnerability in energy storage systems. According to UL9540A and other international standards, energy storage systems that fail the thermal runaway propagation test are not permitted to connect to the public grid. Poor control of thermal runaway can lead to fire hazards, and has been identified as the root cause of many recent safety incidents in the industry, posing a major challenge to the sector's sustainable growth.

The UL 9540A test simulates extreme conditions such as nail penetration, overcharging, and high temperatures to assess how thermal runaway may spread. During testing, Goldwind's GoldBlock L700 was subjected to even stricter layout configurations. It successfully contained thermal runaway at the module level, confirming that a single cell failure does not trigger a chain reaction at the pack level, thereby demonstrating superior product safety.

The GoldBlock L700 features a high energy density design and a fully integrated structure that simplifies transportation. Its unique modular "Lego-style" architecture supports flexible, on-demand deployment across various scenarios from commercial and industrial projects to microgrids and utility-scale storage systems. An exclusive fire suppression isolation module provides multiple layers of protection, significantly enhancing fire safety system availability.

Notably, the system also features grid-forming capabilities, enabling stable grid operation even under extremely weak grid conditions (short-circuit ratio (SCR) = 1). Designed for multi-market compliance, the product accommodates a broad range of global regulatory and technical standards, paving the way for seamless market entry across different regions.

The GoldBlock L700 series has obtained multiple international authoritative certifications and test reports in compliance with standards such as UL, IEC, NFPA, and IEEE, comprehensively validating the product's outstanding performance in safety, reliability, and compatibility.

Throughout its exploration of energy storage technologies, Goldwind has always treated safety as the lifeline of product design. Every energy storage product undergoes stringent testing from component to system level to ensure that safety is maintained at the most granular level. Building on this foundation, Goldwind continues to follow its "high safety, high reliability, high efficiency, and value addition" design philosophy to drive innovation in energy storage technology and deliver safe, reliable, and efficient solutions to customers worldwide.
