The enwitec PowerBackup 63 VERTO PLUS EU(DE) provides an island grid for a full backup to all hybrid inverters of the FRONIUS VERTO PLUS type in the event of a grid failure. The box is available in two variants: one with FRT support of the grid by the inverter, which is normatively required in many EU countries, and a variant without FRT support, which was specially developed for the German market. Both boxes can be operated with a maximum grid-side pre-fuse of 63A and offer the possibility of pre-parameterization for three-pole or all-pole disconnection, depending on the grid type.

Unique Features: The PowerBackup 63 VERTO PLUS EU(DE) stands out for its universal applicability for all new performance classes of the Fronius VERTO PLUS (15 / 17.5 / 20.0 / 25.0 / 30.0 / 33.3 KW). The FRT variant is suitable for the entire EU market (except Germany and Italy) and can be connected to all common supply grids. Another advantage is the connection up to 63A pre-fuse, while Fronius‘ own backup products currently only reach up to 35A.
