More Information
Summary:The utility model belongs to the technical field of photovoltaic equipment, and particularly relates to a fault positioning device and a photovoltaic system, and the fault positioning device comprises a plurality of turn-off assemblies and a fault alarm module. When a certain turn-off assembly breaks down, the turn-off assembly periodically sends out fault signals, and the fault alarm module is close to the turn-off assembly to give an alarm. When any turn-off assembly works normally, the turn-off assembly periodically sends out a normal working signal, and the fault alarm module is close to the turn-off assembly for indication; according to the utility model, through the arrangement of the turn-off assembly and the fault alarm module, after the turn-off assembly breaks down, the turn-off assembly sends out a wireless fault signal, the fault alarm module is close to the intelligent photovoltaic assemblies one by one for detection, and the state is indicated through the corresponding indicating lamp and the bu
