The present disclosure proposes: a distributor measuring box designed to be installed on a photovoltaic solar module, having a housing with a support section embodied to be supported on the solar module, an encompassing side wall, and a cover, and string line feedthroughs and/or string line connectors, and having a string current measuring module that includes a measuring component and an evaluation unit for measuring the string current in the distributor measuring box; a photovoltaic solar module having a plurality of solar cells, in which a distributor measuring box is mounted to the back of the solar module oriented away from the sun; and a photovoltaic system having a plurality of photovoltaic solar modules, having a plurality of string lines, having a generator junction box, and having at least one inverter for supplying the electrical power produced by the photovoltaic generator.

Distributor load cell for determining phase current in photovoltaic installations

A generator junction box for a photovoltaic generator is presented, which has a junction box housing with a back wall and a surrounding side wall, and input modules, each with an integrated quick connector for connecting a generator string line to the associated input module, wherein the input modules are situated directly against the surrounding side wall of the junction box housing in such a way that it is possible to connect the string lines directly to the quick connector of the associated input module from the outside.

Generator connection box for photovoltaic installations

A device for detachably fastening a current conductor to a current transformer housing includes the current transformer housing, a retaining element that is guided through the current transformer housing, a fastening element that is guided through the retaining element, and a clamping element. The fastening element and/or the retaining element are seated against at least some regions of the surface of the current conductor when the current conductor is fastened to the current transformer housing. The fastening element can be rotated about the longitudinal axis thereof so as to fasten and/or detach the current conductor. The clamping element is arranged movably on the current transformer housing so that, in a first position, it allows a translatory displacement of the retaining element along the longitudinal axis. In a second position, the clamping element prevents the transtatory displacement of the retaining element along the longitudinal axis thereof.
