Recently, according to foreign media reports, a serious explosion occurred in Schleswig-Holstein, Germany. A residential building was severely damaged. Judging from the pictures on the scene, the exterior wall of the house was severely damaged.

The local volunteer fire brigade reported: "There was a loud bang, by a pressure wave. Then thick smoke rose." It is understood that although many parts of the building were burning at the time, the fire was quickly brought under control. Fortunately, the severely damaged building was vacant at the time of the incident, but it may be demolished later.

It is understood that this is a single-family villa equipped with photovoltaic + energy storage facilities. According to the North German Broadcasting Corporation NDR, preliminary investigation results show that the cause of the explosion was a failure of the solar energy storage system. At noon that day, photovoltaic power generation had fully charged the energy storage system, but the remaining power was not fed into the power grid and continued to power the energy storage battery, resulting in the explosion.
