Description
The units come factory-assembled and just connect to the switchboard on site. Transfer to backup is automatic, and black start is supported. In standby the 1P and 3P versions draw under 1 W, and the Hybrid X version draws under 4 W in backup. Backup 1P for the single-phase SBSE3.6-50 to SBSE6.0-50 carries 7,300 W continuously, 9,200 W for up to 30 s and 11,040 W for up to 100 ms, and actually switches over in about 100 ms. It sits behind a pre-fuse of up to 63 A, in a 6.16 kg IP65 enclosure rated −40 °C to +55 °C. Backup for Hybrid X comes as a box or a DIN-rail kit with 3- or 4-pole disconnection and serves up to 3 hybrid inverters. The Off-Grid version is meant for systems with Sunny Island X and Storage XL. The Backup 100 and 300 cabinets carry a built-in Data Manager M, a LAN switch and genset management.
How to choose
The inverter decides the version. A single-phase Sunny Boy Smart Energy takes Backup 1P or the 3P Kit, a Sunny Tripower Hybrid X takes the unit of the same name, and the 4-pole version is for sites where the neutral must also be broken when islanding. For a business, size by load. Backup 100 with AC-Box 2 feeds up to 135 kW at 195 A on an NH1 (200 A) fuse and Backup 300 with AC-Box 6 up to 300 kW at 435 A on NH3 (500 A).
