Photovoltaic assembly wire connection box

The utility model discloses a photovoltaic assembly wire connection box comprising a box body, multiple groups of input ends and bypass diodes, multiple illuminating diodes, and multiple current-limiting resistors, wherein the multiple groups of input ends and bypass diodes are arranged in the box body, the illuminating diodes are respectively connected with the bypass diodes in parallel, positive electrodes of the illuminating diodes are connected with positive electrodes of the bypass diodes, the current-limiting resistor are respectively connected with the illuminating diodes in series, and the current-limiting resistors are respectively connected with corresponding bypass diodes in parallel. When the bypass diodes are powered on, the illuminating diodes can be powered on at the same time and can illuminate, positions of battery sheets which do not work in a normal way can be indicated, and therefore targeted measures can be taken. The problem that because part of an assembly is damaged and is not disposed
