An on-board electrical system for a motor vehicle is disclosed. The on-board electrical system has a low-voltage subsystem for at least one low-voltage load, and has a high-voltage subsystem for at least one high-voltage load, and has a starter generator, wherein the high-voltage subsystem is connected to the low-voltage subsystem by means of a coupling unit, wherein the on-board electrical system has a battery which has at least two battery units having individual voltage taps which are routed to the coupling unit. In this case, the coupling unit is designed such that, in a first operating state, the high-voltage subsystem is fed from all of the battery units and the low-voltage subsystem is fed from one battery unit, and, in a second operating state, the high-voltage subsystem is fed from one battery unit and the low-voltage subsystem is fed from at least one battery unit.
