An inverter includes a DC/AC converter connectable to a DC power grid, at least one DC/DC converter arranged upstream of the DC/AC converter and providing a galvanic isolation, and a DC voltage link at the input of the at least one DC/DC converter and connectable to at least one DC power source. The inverter also includes at least one further DC voltage link which is galvanically isolated from the first DC voltage link by the DC/DC converter, on-board voltage rails supplying a controller and other auxiliary devices of the inverter with electric energy; and an on-board supply unit. The on-board supply unit is configured and adapted to feed the electric energy into the on-board voltage rails both out of the first DC voltage link and out of the at least one further DC voltage link.
