Zusammenfassung:The present invention relates to a system for diagnosing an abnormality of a photovoltaic panel based on a voltage and, more specifically, to a system for diagnosing an abnormality of a photovoltaic panel based on a voltage that can distinguish between a state of an actual failure occurrence and a state of a temporary abnormality occurrence. The present invention shows effects in the following manner. According to the present invention, the system can distinguish between a state of an actual failure occurrence and a state of a temporary abnormality occurrence, so it is possible to reduce a frequency of AS call-out and costs by recognizing seriousness according to a type of the abnormality state in advance and can detect the abnormality state only by measuring the voltage, so it is possible to reduce costs for manufacturing. 본 발명은 전압 기반 태양광 발전패널 이상진단 시스템에 관한 것으로, 보다 상세하게는 실제 고장발생 상태와 일시적인 이상발생 상태에 대한 구분이 가능한 전압 기반 태양광 발전패널 이상진단 시스템이다. 본 발명은 다음과 같은 효과를 발휘한다. 즉, 본 발명에 따르면, 실제 고장발생 상태와 일시적인 이상발생 상태에 대한 구분이 가능하기 때문에, 이상상태의 유형에 따른 심각성을 사전에 파악하여 AS 출동 빈도 및 비용절감이 가능하고, 전압측정만으로 이상상태를 감지할 수 있기 때문에, 제조단가를 낮출 수 있다는 장점이 있다.
