Because of their location in residential buildings, high demands are placed on the operational safety of home storage batteries. In the early days of home storage use, cases of battery fires made headlines. More advanced technologies make it possible to virtually eliminate this risk.
For homeowners, investment security is also of decisive importance: the purchase of a PV system or a CHP unit, as well as the integration of a battery storage system into the household's electricity supply, are projects that are planned for decades. The performance of the battery used must therefore be guaranteed over a long period of time - comparable to investing in a new roof truss, for example. This is especially true when home storage batteries are not used as mere solar storage units, but as household buffers. In this function, they are confronted with higher demands on their cycle stability: It is precisely the intensive use of the storage unit for load shifting that is sought in this utilisation concept.
Home storage systems are socially relevant above all for achieving the goals of an environmentally compatible and geopolitically secure energy supply that the energy transition is striving for. This means that the resource efficiency of the batteries used also plays a central role: these can only make a credible contribution to the energy transition if their production itself meets high environmental and resource standards.
