Canadian Solar has successfully completed Large-Scale Fire Testing (LSFT) for its e-STORAGE SolBank 3.0 energy storage system, demonstrating strong fire containment capabilities for utility-scale projects.
Conducted under the CSA C-800:25 §9.7 LSFT protocol, the test assessed the risk of fire propagation between adjacent enclosures in the event of a fully developed internal fire. The SolBank 3.0 met all safety criteria, with no fire spread and all structural elements remaining intact – meeting critical NFPA 855 safety objectives.
Independent observers from CSA Group and Energy Safety Response Group (ESRG) verified the test results, confirming SolBank 3.0’s robust passive containment system.
Josh Dinaburg, Fire Test Specialist at CSA Group, commented, “Key stakeholders in the energy storage industry have raised justifiable concerns about the ability of BESS to limit the spread of fire between units without relying on complex extinguishing systems or putting first responders at risk. The e-STORAGE system demonstrated that an aggressive fire consuming all available fuel in one unit does not ignite new fires and spread to adjacent units. This is critical performance data for the end-users and site managers, first responders, insurance adjusters, and the community at large where these systems may be installed.”
