Frame for photovoltaic modules
The invention relates to a frame for photovoltaic modules into which connection sockets and module electronics can be integrated so as to be easily accessible and which is simultaneously used as a guide system for connection cables.
1. A module frame for photovoltaic modules, characterized in that the module frame comprises vertical webs that are offset from an outer edge of the module frame by at least a distance d in the direction of the frame module center, such that a cross-section through the module frame forms an outer volume that is at least partially open having at least one vertical web of the vertical webs limiting said outer volume toward the center of the module frame, wherein the outer volume is designed for cable routing and for integrating connection sockets or module electronics, wherein the module frame has a connection socket integrated into the outer volume of the module frame and a connection plug with two or more contacts, wherein the module frame comprises a module electronics, wherein the module frame has webs for engaging in grooves of module electronics, wherein the module electronics are fixed by snapping one or more grooves located in the housing of the module electronics into said webs, wherein the snapped-in module electronics are slidable onto the connection plug of the connection socket within the frame.
2. The module frame according to claim 1 , characterized in that the module frame consists of metal.
3. The module frame according to claim 1 , characterized in that the length of the distance d is in the range of 3 mm to 40 mm and that the module frame has a height h in the range of 25 mm to 40 mm.
4. The module frame according to claim 1 , characterized in that the module frame has additional guide lips or guide channels for cable routing.
5. The frame module according to claim 1 , wherein the cross-section of the outer volume is u-shaped, wherein a basis of the “u” is formed by the vertical webs.
6. The frame module according to claim 1 , wherein the vertical webs are arranged in pairs, wherein a first vertical web of each pair is arranged at the distance d toward the center of the frame module, wherein a second vertical web of each pair is arranged in parallel to the first vertical web at a distance greater than d towards the center of the frame module.
7. The frame module according to claim 1 , wherein the connection socket is fitted into the outer volume of the module frame, such that the connection socket does not protrude from the module frame.
8. A photovoltaic module with a module frame according to claim 1 .
9. The photovoltaic module according to claim 8 , characterized in that the connection socket is equipped with a plurality of by-pass diodes.
10. The photovoltaic module according to claim 8 , characterized in that connection cables are guided in the outer volume of the module frame.
11. The photovoltaic module according to claim 8 , characterized in that it has a microinverter integrated in the module frame.
