Embodiment Construction

[0059] figure 1 A known generator terminal box 2 is shown, which has a terminal box housing 4 with a surrounding side wall 6 and a rear wall 5 . The surrounding side wall 6 has an opening 8 for the passage of the column conductors 24 . Different modules are arranged inside the generator junction box 2, including an input module 10a, a measurement module 32, a connection module 34 and other modules, such as an overvoltage protection module, and a main disconnect switch 38 is also arranged.

[0060] exist figure 1 The input module 10a for the positive pole shown on the left in the center is connected with five column conductors 24 .

[0061] exist figure 1 The string conductors shown in are individually guided through the opening 8 of the surrounding side wall and connected to the input module 10 a inside the generator terminal box 2 by means of screw connections. The input modules 10a are simple terminal blocks in the example shown.

Abstract

A generator connection box for a photovoltaic generator is presented, which comprises a connection box housing having a rear wall and a circumferential side wall and input modules each having an integrated quick connector for connecting a generator string line to the associated input module, wherein the input modules are arranged directly on the circumferential side wall of the connection box housing in such a way that the string lines can be connected to the quick connector of the associated input module directly from outside.

Description

technical field [0001] The invention relates to a generator junction box for a photovoltaic generator and an input module for installation in the generator junction box. Background technique [0002] In photovoltaic generators for generating electrical power from sunlight, the total generator is usually divided into several strings / strangs, which consist of a plurality of photovoltaic solar modules connected in series. The individual strings of photovoltaic generators are connected in parallel with each other. [0003] Usually an electrical connecting wire is routed from each parallel-connected string to the generator junction box. Thus, the conductors of all strings are brought together in the generator junction box. [0004] The connection wires of each photovoltaic generator set, referred to as the string wires, usually enter the generator junction box through the housing wall separately, and are connected to the devices located here inside the generator junction box. ...
