摘要

The invention relates to an inverter (10) comprising at least two direct current inputs (11a, 11b) which are coupled to a shared DC intermediate circuit that is connected to an inverter bridge (14). The inverter (10) is characterised in that at least one of said direct current inputs (11a, 11b) is coupled to an additional DC intermediate circuit. The invention also relates to a PV installation comprising such an inverter (10), as well as to a method for controlling such an inverter (10) of a PV installation, in which a power flow of at least one of the direct current inputs (11a, 11b) is directed, as a function of a correspondingly-coordinated actuation of the voltage converter (12a, 12b) and an additional voltage converter (22) associated with the additional DC intermediate circuit, into said DC intermediate circuit and/or said additional DC intermediate circuit.
