Abstract: A solar inverter assembly has a first housing part, which is used as a heat sink, and a second housing part for holding electronic components of the solar inverter. The first housing part has a first air inlet opening, a first air outlet opening and a first air channel connecting the air inlet and air outlet openings. Air flows on the basis of natural convection through the first air channel. The second housing part has a second air inlet opening, a second air outlet opening, and a second air channel which connects the second air inlet opening to the second air outlet opening. Air flows on the basis of natural convection through the second air channel. At least one electronic component, which is insensitive to dust, of the solar converter, for example a transformer or an inductor, is mounted in the second housing part in direct thermal contact with the first housing part and within the second air channel.

Abstract: A mount module for an inverter includes a housing element with a recess being open to the front face, for holding a single inverter. The upper face and the lower face of the housing element are complementary to one another, and/or the right side and the left side of the housing element are complementary to one another, and/or the rear face of the housing element is complementary to itself. The respective side or sides and face or faces of the housing element each have at least one connection device. A relatively large number of the mount modules can be disposed one above the other, alongside one another, and/or with their rear faces against one another and can be connected to one another in order, for example, to form a central inverter unit for large photovoltaic installations.

Abstract: In order to enable an electrical appliance, in particular for a domestic appliance, an economically produced control panel for different models of the appliance is provided. The control panel has a sensor film forming a switch panel with a plurality of individual switch zones. Each of the switch zones can be selected independently of each other. A specific selection of the switch zones is activated depending on what devices are fitted in the electrical appliance. In addition, the sensor film is assigned an externally accessible keypad having a plurality of individual visually identified button zones assigned to each of the activated switch zones. The sensor film is in particular a film having a printed piezo-layer from which the individual switch zones are formed.

Abstract: A housing part for a domestic appliance, preferably a dishwasher, a refrigerator, a freezer, a washing machine or a laundry dryer is uniquely constructed. The housing part has a load-bearing component part formed of an expanded thermosetting plastic, in particular of polyurethane integral foam. In particular, the housing part forms a door or a cover of a domestic appliance.
