PNN 83371
Work Detail The cause of the fire in the lithium-ion battery storage system is still unclear. E3/DC intends to support LG Energy Solution in the investigation and will replace battery modules at 77 residential customers as a precaution. Just over a week ago, a fire broke out in Werne, a German town in North Rhine-Westphalia. The towns volunteer firefighters were alerted to a "suspected basement fire" via a digital alarm. According to their report, no one was home in the house, which was filled with smoke when the firefighters arrived. The smoke was coming from a residential storage battery that had caught fire in the basement and ignited for unknown reasons. “The team attempted to extinguish the 6 kWh battery, which proved difficult due to the flames repeatedly igniting behind the sheet metal cladding of the cabinet,” the volunteer firefighters’ report reads. When questioned, a fire service spokesperson told pv magazine that it was a residential battery type S10 of the E3/DC brand. E3/DC also confirmed this, commenting on the incident: “ In connection with the fire that occurred in Werne on 18 November 2024, we can confirm that a battery module from the manufacturer LG Energy Solution can be seen in the photos taken during the firefighting operation.” The battery module was connected to an E3/DC S10E 6.5 domestic power station that was put into operation in 2019 and caught fire for reasons that have not yet been precisely analysed. “Judging by the appearance of the extinguished battery module, it appears to have behaved in accordance with the standards in the event of a fire,” E3/DC explained. “We are assisting LG Energy Solution in determining the possible causes based on our detailed analyses of the battery. Regardless of the outcome of further investigations, E3/DC will proactively replace battery modules from the same production batch of cells as a precautionary measure,” the company continued. A total of 77 customers have been affected and E3/DC will inform them accordingly. As for the actual extinguishing operation, the Werne fire brigade also reported that they had deactivated the system in the sub-distribution box in the basement and continued to cool the battery. “However, the thermal imaging camera clearly showed that the battery continued to ignite when the cooling was interrupted and the temperature inside rose again,” he continued. Finally, the fire brigade called the installer of the storage system to the scene of the fire. In the meantime, they continued to extinguish the battery with gel extinguishers. Following the installers instructions, the firefighters finally disconnected the DC connection from the battery and "the battery, which was screwed to the wall, had to be laboriously dismantled using breaking tools." The dismantled battery was then immersed outside in a 600-litre portable container and further cooled. Due to the fire damage in the basement and damaged power lines in the fire room, RWE electricity distributor technicians alerted by the incident switched off the power to the house via the main fuse box, according to the fire brigade. Following control and extinguishing measures, air extraction openings were created in the smoke-filled floor and in the basement, and the high-performance fan was used to create forced ventilation. Firefighters were on site for almost four hours with 38 volunteers to extinguish the blaze. Firefighters from the nearby town of Lünen also took part in the operation. There have been repeated fires involving home storage PV systems in Germany in the past. However, considering the more than 1.5 million systems installed in Germany, the number of fires is insignificant.
