Accessory SMA Backup pour Sunny Tripower HybridX (version DIN 3 pôles) - 2 years warranty

The SMA Backup solution for Sunny Tripower Hybrid X, DIN rail version with 3-pole switching, is the compact kit that adds whole-home backup power to a Hybrid X hybrid inverter paired with an SMA high-voltage battery. Functionally it does the same job as the box version: it detects a grid failure, disconnects the installation from the public grid automatically and allows the inverter to continue supplying the loads in island operation from battery and PV. The changeover is automatic thanks to integrated grid-failure detection, and standby consumption remains below 1 W in normal grid operation. It is rated for 63 A and covers the whole domestic circuit, not a separate backup sub-panel. The difference lies in the format. Supplied as a DIN rail kit for mounting directly in the existing distribution or meter cabinet, it keeps the installation tidy and avoids an additional wall-mounted enclosure — the preferred option on new builds and wherever the cabinet has free modules. Push-in terminals speed up wiring. This 3-pole version switches the three phase conductors, with the neutral remaining connected. Rated IP20 for in-cabinet use, it measures 249 × 110 × 110 mm and weighs just 1.5 kg. With a 2-year manufacturer warranty, it is the most compact and economical route to backup power on a Hybrid X system.
