30 kWh battery explosion destroys home in Germany


  • Germany experienced another accident involving a battery storage system on Oct. 6.

“At around 2 p.m., the fire safety department of the Wernges district was alerted of smoke coming from a two-family house,” Police Chief Inspector Andre Müller of the East Hesse Police Headquarters told pv magazine.

When the police arrived at the scene, local fire departments were already present, but they could not detect any fire. However, an explosion had occurred, resulting in the collapse of the home’s eastern wall.

The explosion has been linked to a 30 kWh storage unit in the basement. Preliminary findings from the investigation suggest that a technical defect may have caused the explosion, according to the police officer.


The homeowners managed to evacuate the house independently. The police reported that three individuals sustained minor injuries, including the homeowner, a resident, and a neighbor.

The police estimate the damage to be in the mid-six-figure range, rendering the house currently uninhabitable. Firefighters secured the area with construction fences and provided support to prevent the residential building from collapsing. The police did not disclose any information about the battery manufacturer.

During the latter part of September, there were multiple instances of home photovoltaic storage systems catching fire. In total, pv magazine has learned about five similar incidents in Germany and Austria.

  1. This one was quite likely the gas boiler, which was in the same room.

    The batteries and inverters are clearly not damaged in site photos, but the gas boiler is in pieces.
    Not a hard guess as to what went wrong there.
