Sungrow SBH Series Achieves UL 9540B Certification for Enhanced Energy Storage Safety

In Australia, federal and state incentive programs have spurred household adoption of energy storage systems, driven by homeowners' goals to reduce electricity costs and enhance energy independence. As the market expands rapidly, a critical question emerges: how can energy storage systems ensure reliable, everyday safety that Australians can truly trust?

According to Finn Peacock, founder of leading solar industry platform SolarQuotes, "User focus is shifting from upfront cost and capacity to installation quality and long-term manufacturer accountability." This shift underscores that genuine safety and reliability stem from a manufacturer's technical expertise and sustained commitment.

As a global leader in renewable energy technology, Sungrow prioritizes safety in its energy storage innovations. The Sungrow SBH Series has recently obtained UL 9540B certification, one of the most rigorous safety standards for residential energy storage systems under 20kWh. Recognized industry-wide, UL 9540B assesses a system's capacity to prevent fire propagation and manage risks under extreme failure conditions.

The certification test simulates a worst-case scenario by intentionally inducing thermal runaway in a fully charged system. Over 24 hours of continuous extreme verification—including closely spaced battery units, deactivated active fire suppression, and repeated ignition triggers—the SBH system demonstrated exceptional inherent safety. It exhibited no fire propagation, no explosions or projectile hazards, and self-extinguished within one hour. This outcome reflects a deeply engineered, multi-layered safety architecture that acts as an invisible "firewall" for homes.

Cell-Level Isolation: To prevent escalation from a single cell failure, Sungrow uses advanced insulation material capable of withstanding temperatures exceeding 800°C. Each cell is individually isolated, ensuring that heat transfer is contained and chain reactions are prevented at their source, protecting both property and occupants.

Advanced Heat Dissipation: The advanced thermal design at the base of each module enables rapid and uniform heat dissipation, effectively preventing localized overheating and heat accumulation, significantly reducing the risk of thermal runaway during operation.

Millisecond-Level Pressure Relief: When internal pressure rises abnormally, Sungrow's unique L-shaped pressure relief channel works with strategically positioned vents around the module. This design allows high-temperature gases and pressure to be safely expelled within milliseconds, effectively eliminating explosion risk.

Structural Protection: In extreme conditions, physical integrity becomes the ultimate defense. The SBH enclosure features a high-strength structural safety latch, ensuring the system remains securely sealed even during sudden internal pressure spikes, delivering an additional layer of protection.

As a global leader in energy storage solutions, Sungrow delivers more than just performance. With 29 years of global technology expertise and over 12 years of proven installation experience in Australia, Sungrow has powered more than 400,000 homes and businesses nationwide. From installation to operation, Sungrow positions itself as a trusted partner for homeowners seeking worry-free, high-quality clean energy solutions.
