Title:
PHOTOVOLTAIC POWER GENERATION SYSTEM AND INSPECTION METHOD
Document Type and Number:
Japanese Patent JP2017200286
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To simplify an inspection of a bypass diode provided in a photovoltaic power generation module.SOLUTION: A photovoltaic power generation system 1 including a bypass diode, comprises n string systems 11-1 to 11-n. A string has switches 13-1 to 13-n on a plus terminal side and one of switches 14-1 to 14-n on a minus terminal side. When switching to a bypass diode inspection state from an electric power generation state, an intercept 51 of the pulse terminal side and a pulse contact point 53 are connected to each other in a switch part. On the basis of a state in which an intercept 52 of the minus terminal side and a minus contact point 54 are connected to each other, the intercept 51 of the pulse terminal side and the minus contact point 54 are connected to each other and the intercept 52 of the minus terminal side and a contact point 55 of the plus terminal side are connected to each other.SELECTED DRAWING: Figure 1
