Bidirectional wall boxes in Germany for private individuals
In Germany, private individuals are generally allowed to use bidirectional wall boxes, but their use is subject to certain technical and legal framework conditions that are intended to ensure that the devices can interact safely and efficiently with the power grid. There are specific norms and standards that regulate the connection and operation of charging equipment, such as requirements for residual current, overcurrent, network and system protection, which are defined in the VDE application rules VDE-AR-N 4100, VDE-AR-N 4110, and VDE-AR-N 4120.
In addition, when using bidirectional charging techniques such as Vehicle-to-Grid (V2G) or Vehicle-to-Home (V2H), interoperability and IT security must also be ensured to enable efficient and safe communication between the vehicle, the wall box, and the power grid.
The introduction and use of bidirectional charging technologies in Germany is still relatively new and subject to dynamic development. Interested private individuals should therefore seek comprehensive information before installing a bidirectional wall box and, if necessary, consult experts for planning and installation.
