Who is it for?

The Backup Box suits single-phase Huawei inverters of the L1 series (not for the three-phase M1 series). When installed outdoors, it should not be exposed to direct sunlight; a sheltered location or a cover is recommended. An SPD surge protection device must be installed on the grid side. You should leave the installation to a qualified electrician. In rooftop PV systems, the Backup Box controls the grid-connected and off-grid status of the inverters. Before buying, please check whether your inverter model is on the compatibility list in the technical specifications.

We will gladly advise you personally on selection and use: by phone on +49 931 760 260 40 or by e-mail at kontakt@energie24.shop. Pickup at our Veitshöchheim warehouse is possible by arrangement.
