Myers Emergency & Power Systems, a U.S.-based leader in intelligent power infrastructure solutions, has announced that its EnerShed 2.0 Battery Energy Storage System (BESS) has successfully passed the UL 9540A Large-Scale Fire Test 6th Edition conducted by the CSA Group, becoming the first company to achieve this milestone in North America, reinforcing its market leadership in safety and regulatory compliance.
“At Myers, safety is not a checkbox. It is a core engineering principle that shapes every product decision we make,” commented Chief Product Officer Troy Renken. “Successfully completing the UL 9540A 6th Edition Large-Scale Fire Test reflects our commitment to designing systems that customers and communities can trust, while also staying ahead of evolving codes and standards. Being the first in our industry to achieve this milestone cements Myers’ position as an emerging market leader in the BESS category.”
Published in March, the UL 9540A 6th Edition introduces the most substantial updates to the standard in years, including formal integration of LSFT testing into the certification framework. Manufacturers must now demonstrate that a thermal runaway event in one unit will not propagate to adjacent units under defined conditions. To support transparency and validation, Myers completed this testing at Safe Laboratories under the observation of the CSA Group and independent subject matter experts, including Atar Fire, a leading fire protection engineering firm with nearly two decades of experience.
