A connecting device which can be arranged relative to a photovoltaic module for the purpose of electrically connecting a plurality of photovoltaic modules to one another and/or to an inverter device comprising at least a housing. The housing includes a first housing element and a second housing element; first connection devices for electrical connection to the photovoltaic module arranged in the first housing element; and second connection devices for electrical connection to a further connecting device or to the inverter device of a semiconductor circuit having at least one semiconductor component arranged in the second housing element. The connecting device further includes first contact devices, which are associated with the first housing element, and second contact devices, which are associated with the second housing element. The semiconductor circuit arrangement can be electrically connected to the first connection devices.
