Sungrow's PowerKeeper has achieved triple UL 9540A certification, undergoing comprehensive thermal runaway testing across cell, module, and unit levels. This certification confirms that PowerKeeper can effectively contain thermal runaway in high-density environments such as shopping malls and factories, addressing the limitations of traditional single-tier testing.
The system demonstrated minimal thermal spread even under extreme conditions, with a peak cell temperature of 595.2°C, while maintaining temperatures significantly below UL thresholds in adjacent units. The integration of advanced active safety mechanisms enhances everyday operational safety, establishing a comprehensive safety architecture. This development is pivotal as the global demand for safe and efficient commercial and industrial energy storage solutions continues to grow.
