The invention relates to a mounting (6) for a dc-ac converter (3) in a photovoltaic system (1), the mounting being designed to detachably accommodate the converter (3). The converter (3) can be connected to at least one solar module (2) and an alternating current supply (4) via at least one connection cable (5). The invention also relates to a method for fitting a dc-ac converter (3) to a mounting (6) of this type. To allow the simple and rapid fitting of the dc-ac converter (3), a first part (8) of a connector (7) for connecting the connection cable (5) of the dc-ac converter (3) and also a device (9) for guiding the converter are provided on the mounting (6), the guide device (9) being designed to automatically bring the first part (8) of the connector (7) into contact with a second part (10) of the connector (7) that is located on the dc-ac converter (3).
