They protect sensitive inverters and grid connection equipment through integrated surge protection (Type 1 + 2 + 3) and upstream fuse disconnectors. Each box is delivered as a ready-to-install custom build: all components pre-assembled, tested and ready to connect.
The design supports all common grid types (TN-C, TN-S, TN-C-S) and is suitable for large cable cross-sections (e.g. NYY-J 4 × 300 mm²). With high current-carrying capability and individual engineering, the AC box is a reliable solution against surge events – made in Germany in the Allgäu region.
