Sigenergy, a leading innovator in the energy sector, and Intertek, a global provider of Total Quality Assurance, have officially released a joint white paper titled Comprehensive Safety Protection for C&I Energy Storage Systems. The white paper, which offers detailed insights into safety strategies for commercial and industrial (C&I) energy storage systems, was initially previewed at Intersolar Europe 2025 during a joint launch ceremony.
The preview was presented by Samuel Zhang, Chief Technology Officer at Sigenergy, and Klaus Herrmann, Global Certifier at Intertek. The official release marks the full publication of their research and reinforces both organizations’ commitment to enhancing safety standards within the energy storage industry.
As the global energy transition continues to gain momentum, C&I energy storage systems have emerged as critical components in improving energy efficiency and stabilizing power supply and demand. However, the rapid adoption of these systems has also elevated safety concerns, prompting the need for more robust standards and reliable safety solutions.
In response, Sigenergy and Intertek collaborated to produce the white paper, which aims to establish industry-wide benchmarks for the safe deployment and operation of C&I energy storage systems. The document addresses major safety challenges—including thermal runaway, fire mitigation, and system complexity—offering technical perspectives grounded in the assessment of Sigenergy’s SigenStack platform.
With its modular and scalable design, SigenStack is positioned as a forward-looking model for safe and efficient energy storage. According to the white paper, SigenStack has undergone a comprehensive suite of internationally recognized and automotive-grade safety tests, such as UL 9540A, IEC 62619, and GB/T 36276. Test results highlighted in the publication show the system preserved structural integrity under extreme conditions and demonstrated operational efficiency exceeding 95%.
Samuel Zhang, Chief Technology Officer at Sigenergy, stated, “At Sigenergy, we believe safety and innovation must go hand in hand. Through our collaboration with Intertek, we are proud to contribute to the development of high-integrity safety standards and help drive the global transition toward smarter and more sustainable energy systems.”
Klaus Herrmann, Global Certifier at Intertek, commented, “The release of this White Paper marks a significant step in our shared commitment to advancing safety in the energy storage sector. As a global leader in quality assurance, Intertek remains dedicated to enabling innovation through rigorous testing and certification, helping companies meet evolving safety requirements and expand confidently into new markets.”
The publication aims to foster best practices and support the sustainable growth of the global energy storage sector by encouraging the adoption of advanced safety protocols and innovative system designs.
