Sungrow Live Streams Fire Test on PowerTitan ESS System to Show Its Safety

Sungrow recently livestreamed a fire test of its PowerTitan energy storage system. The test involved four 2,752 MWh PowerTitan systems, and the container was intentionally set on fire to test that it could contain thermal runaway without spreading to other units.

“This elevates our commitment to industry security and trade transparency to a level that few have achieved,” said Hank Wang, president of Sungrow Americas.

The test, conducted in May at a third-party laboratory in China, simulated a real-world energy storage plant scenario and was similar to testing conducted under the UL 9540A test, which Sungrow had previously conducted to achieve UL compliance 9540. During the test, the explosion panels at the top activated automatically, venting the fire upward without spreading to adjacent battery cabins and energy storage units. The superior exhaust and ventilation design as well as the fire-resistant partitions allowed the PowerTitan1.0 energy storage system to pass this real fire test, thus achieving the expected objectives.

Sungrow's PowerTitan battery energy storage system series minimizes the risk of fire by using liquid cooling, which prevents dust and moisture from entering the system. The systems effectively suppress the spread of thermal runaway with rapid arc termination, self-sealing coolant loop connectors, inter-rack fusion protection and advanced temperature management, which limits battery cell variations at 2.5°C.

“By ensuring the highest security standards, Sungrow’s technology alleviates security concerns and helps encourage the adoption of large-scale storage systems across the energy sector,” Wang said.
