Beschreibung
Zusammenfassung:	The invention relates to an inverter (1) for converting a direct voltage (UDC) into an alternating voltage (UAC) for feeding into a single-phase three-conductor network (3) and for supplying loads (4), comprising a DC input (5), a link (6) having a link center point (7), a DC/AC converter (8) having at least two half bridges (12, 13), a control device (9), and an AC output (10) for connecting to the single-phase three-conductor network (3) and the loads (4). The invention further relates to a method for operating such an inverter (1). According to the invention, the control device (9) is designed to connect, in emergency power operation (BOM), one half bridge (12) of the DC/AC converter (8) to an outer conductor (L1) of the AC output (10), to connect the other half bridge (13) of the DC/ACconverter (8) to another outer conductor (L2) of the AC output (10), and to connect the link center point (7) to the neutral conductor (N) of the AC output (10) and to halve the amplitude of the output signal (U1BOM, U2BOM)
