A New Era in Fire Protection for Residential Energy Storage
As more homeowners turn towards residential energy storage systems, the need for reliable safety measures has become a pressing concern. Any misstep can lead to grave consequences, especially when it comes to fire-related incidents. Sungrow has recognized this urgency and proactively responded to enhance safety protocols within the industry. After completing successful combustion verifications for utility-scale energy storage, they have now focused their efforts on the residential energy sector.
Achieving Milestones in Fire Safety Testing
The SBH Series: Residential Energy Storage System (ESS) has achieved a remarkable milestone by successfully passing the world's first UL 9540B large-scale fire test. This test is renowned for its rigor and specifically designed for residential energy storage systems up to 20kWh. It sets the highest safety standards in the industry. These systems undergo demanding evaluations mimicking extreme fire scenarios like thermal runaway and gas buildup.
Understanding UL 9540B Standards
UL 9540B puts energy storage systems through the ultimate trials to measure their resilience against raging fire hazards. The testing simulates real-world conditions where emergency situations might arise, assessing the systems on their ability to prevent explosions and manage secondary risks. This rigorous standard necessitates exemplary engineering in system insulation, gas management, and thermal runaway suppression.
Noteworthy Performance by Sungrow’s SBH Residential ESS
In a grueling 24-hour test, Sungrow's SBH Residential ESS faced numerous challenges, which included having closely packed battery units without active fire suppression systems and enduring continuous ignition triggers. Despite these intense conditions, the system displayed its outstanding safety controls and met all criteria for evaluation.
Exceptional Fire Containment: Locking Risks Away
During the UL 9540B fire safety examination, the SBH Residential ESS showcased its unmatched fire containment capabilities. The system utilized advanced features, including fire-resistant insulation and thermal management mechanisms, which limited flames to just one area during an ignition event. Surprisingly, even adjacent units remained cool, with internal temperatures only reaching 21°C, significantly below the venting threshold.
Self-Extinguishing Capability: Controlling the Flames
The innovative structural designs allowed rapid heat dissipation within the SBH Residential ESS, which effectively confined thermal runaway. Even without any fire suppression measures from outside, flames self-extinguished in under an hour, showcasing the system's remarkable safety design.
Avoiding Explosions: Assuring Maximum Safety
Throughout the testing phase, the SBH Residential ESS experienced no explosions or combustion events, primarily due to its robust structural integrity and fire resistance. Homeowners can feel reassured knowing that this system prioritizes their safety above everything else.
Building Trust in Home Energy Use
This achievement further enhances confidence in the SBH Residential ESS’s reliability, covering every aspect from thermal runaway prevention to fire-control measures. Homeowners can now trust that this system delivers unparalleled safety, allowing them to use energy without worry.
