  • Patent number: 10010011
    Abstract: The disclosure relates to an inverter having a first housing module, a second housing module, removably connected to the first housing module, and power-electronic components in both housing modules, wherein a cooling air channel, opening in the surroundings of the inverter, is delimited in the circumferential direction partially by the first housing module and partially by the second housing module. The first housing module is configured to mount to an external structure and the second housing module is configured to mount to the first housing module. The cooling air channel extends at a distance to a mounting plane of the inverter defined by the first housing module opposite the external structure.

  • Patent number: 7955134
    Abstract: A photovoltaic inverter with an inverter housing includes at least a first chamber and a second chamber separated by a wall. The first chamber has a higher Ingress Protection (IP) rating than the second chamber. The first chamber accommodates at least one electronic component part of the photovoltaic inverter. A surface of the wall facing the second chamber provides a plurality of fuse housings. Each of the fuse housings accommodates a fuse and being coupled to a plug connector electrically connected to the fuse. The plug connectors provide electrical connections to the first chamber.
