Accessory SMA Backup pour Sunny Tripower HybridX (version Box 4 pôles) - 2 years warranty

The SMA Backup solution for Sunny Tripower Hybrid X, box version with 4-pole switching, gives a Hybrid X hybrid inverter and an SMA high-voltage battery the ability to supply the whole home when the public grid fails. On grid failure the unit disconnects the installation from the utility automatically and lets the inverter run in island mode, powering the loads from battery and PV. Grid-failure detection is integrated, no user action is needed, and standby consumption stays below 1 W during normal operation. It is rated for 63 A and secures the complete domestic circuit, so there is no need to build a separate backup distribution board. The 4-pole version switches the three phases and the neutral conductor, providing all-pole disconnection. This is the variant to specify where the grid configuration or the applicable installation rules require the neutral to be isolated as well — a frequent requirement in Belgian and French installations. It ships as a pre-assembled wall-mounted box, IP65 rated, 506 × 236 × 260 mm, 6.6 kg, and installs beside the inverter without touching the existing meter cabinet. Delivered with a 2-year manufacturer warranty, it is the safe choice for compliant, whole-home backup on a Sunny Tripower Hybrid X system.
