The invention relates to a system having an energy storage device and a DC voltage supply circuit, wherein the energy storage device has at least two energy supply branches, which are each coupled at a first output to at least one respective output terminal of the energy storage device in order to generate an AC voltage at the output terminals, and at a second output to a shared bus, wherein each of the energy supply branches has a plurality of energy storage modules connected in series. The energy storage modules each comprise an energy storage cell module having at least one energy storage cell and a coupling device having a coupling bridge circuit made from coupling elements. The coupling elements are designed to selectively connect the energy storage cell module to the respective energy supply branch or to bypass the energy supply branch. The DC voltage supply circuit has: a bridge circuit having a plurality of first feed terminals, each of which is coupled to one of the output terminals of the energy storage device; two feeding nodes, at least one of which is coupled to the bridge circuit; and a module-tapping circuit that has at least one module switching branch having a commutating diode. Each of the at least one module switching branches connects a coupling node between two energy storage modules of one of the energy supply branches switchably to a feeding node.
