Cable Module for Module Inverter of a Photovoltaic Generator

摘要

The disclosure relates to alternating-current cabling for a photovoltaic generator having a plurality of photovoltaic modules equipped with module inverters. The alternating-current cabling comprises an alternating-current trunk line and branch cables connected thereto for feeding the alternating current from the plurality of module inverters into the common alternating-current trunk line, such that the alternating-current trunk line can be routed at a distance from the module inverters, and is composed of a plurality of pre-assembled cable modules. The pre-assembled cable modules each comprise the following components: a first and a second trunk-line plug connector; a trunk-line cable segment that connects the first and second trunkline plug connectors; and a branch cable electrically connected to the trunk-line cable segment.

主权项

1. An alternating current cabling system for a photovoltaic generator which comprises a plurality of photovoltaic modules equipped with module inverters, comprising an alternating current trunk line and drop cables connected thereto for feeding the alternating current from the plurality of module inverters into the common alternating current trunk line, so that the alternating current trunk line can be installed spaced from the module inverters, the alternating current cabling system being composed of a plurality of preassembled cable modules, each of the pre-assembled cable modules comprising the following components:
a first and a second trunk line connector; a trunk line cable section connecting the first and second trunk line connectors; and a drop cable electrically connected to the trunk line cable section; wherein the cable modules are serially connected together by means of their first and second trunk line connectors to form a chain so that the trunk line cable sections serially connected in this manner form the alternating current trunk line; wherein each of the module inverters has associated therewith a cable module including a drop cable, so that the module inverters are connectable to the alternating current trunk line by means of the respective associated drop cable; and wherein one cable end of each of the drop cables is directly connected and hardwired to one of the first or second trunk line connectors of the associated cable module.
