flag The Sungrow SBH Series became the first home battery to pass UL 9540B’s strict fire safety test, proving it safely contains fires without external help.

flag The Sungrow SBH Series residential energy storage system has become the first in the world to pass UL Solutions’ UL 9540B fire safety test, a stringent standard for home energy systems up to 20kWh. flag During a 24-hour test simulating extreme fire conditions, the system contained flames within its pressure relief area, prevented explosions and re-ignition, and kept adjacent units cool, with no external intervention needed. flag Advanced thermal management and structural design enabled self-extinguishing flames within an hour, marking a major leap in residential energy storage safety and setting a new industry benchmark.
