摘要： An inverter for a photovoltaic system includes a substantially planar baseplate having a front and a rear, wherein the rear forms an outer rear wall of the inverter, and having at least one platform-like elevation that rises in the direction of the front of the baseplate. The inverter also includes a printed circuit board having one or more heat-generating components mounted thereon, wherein the printed circuit board is installed on the baseplate such that the one or more heat-generating components are arranged on the printed circuit board in the region of the platform-like elevation and are in thermal contact with the platform-like elevation. The inverter further includes a potting compound that fills a space on the front of the baseplate and surrounds at least partially the printed circuit board, and a cover arranged on or in the potting compound that adjoins the baseplate, so that the baseplate and the cover surrounding at least part of the potting compound form a housing, The inverter also includes at least four DC connectors that are arranged in pairs on at least one of the lateral end faces of the housing and at least part of which is cast in the potting compound, and an AC connector that is arranged on one of the lateral end faces of the housing, wherein electrical contacts of the AC connector are connected to the printed circuit board.

摘要： An inverter includes a DC/AC converter, a DC intermediate circuit on the direct current input side of the DC/AC converter, multiple DC/DC converters connected in parallel to one another on the output side to the DC intermediate circuit, multiple inputs each coupled to one of the DC/DC converters, and an EMC filter connected between the inputs and the DC/DC converters. The EMC filter includes chokes in all current-carrying lines between the inputs and the DC/DC converters and filter capacitors between the inputs and the DC/DC converters leading from all the current-carrying lines to ground. The chokes in all current-carrying lines from the at least two inputs are formed by means of choke windings on a common core of a current-compensated choke.
