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

The SMA Backup solution for Sunny Tripower Hybrid X, box version with 3-pole switching, adds whole-home backup power to a Hybrid X hybrid inverter combined with an SMA high-voltage battery. Its role is to detect a grid failure and disconnect the installation from the public grid automatically, so the inverter can switch to island operation and continue to supply the loads from the battery and the PV array. Integrated grid-failure detection performs the changeover without user intervention, and standby consumption stays below 1 W in normal grid operation. Rated for 63 A, it covers the domestic circuit as a whole rather than a separate backup sub-panel, which avoids rewiring the priority circuits. This 3-pole version switches the three phase conductors while the neutral remains connected — the usual arrangement where the grid configuration and the local wiring rules allow it. It is delivered as a pre-assembled box with removable lid and installation cover, designed for wall mounting next to the inverter, which makes it particularly suitable for retrofits where the existing meter cabinet has no room left. The IP65 enclosure measures 506 × 236 × 260 mm and weighs 5.5 kg. Supplied with a 2-year manufacturer warranty, it is a simple and dependable way to offer real energy resilience.
