Sungrow's SBH Series, a residential energy storage system, has successfully undergone the UL 9540B test — a specific and demanding safety evaluation conducted by UL Solutions. This assessment is designed to simulate a worst-case scenario by intentionally inducing a thermal runaway — an uncontrollable self-heating state — in a fully charged unit to observe if the failure propagates to adjacent units.
The reported results indicate that Sungrow's SBH Series effectively contained the fire and heat to the single affected unit, prevented explosions, and saw flames self-extinguish without external intervention. The manufacturer attributes this performance to specific engineering considerations — from cell-level insulation and strategic heat dissipation to integrated pressure relief mechanisms.
Sungrow's achievement is positioned as an industry first for residential energy storage systems.
