Abstract

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Fehlererkennung in einer Photovoltaik-Anlage (1). Dabei wird eine erste Ausgangsspannung (U0, UMPP) der Anlage (1) und/oder eines aus dieser Ausgangsspannung (U0, UMPP) abgeleiteten ersten Parameters zu einem ersten Zeitpunkt in einem ersten Betriebszustand der Photovoltaik-Anlage (1) ermittelt. Zu einem zweiten Zeitpunkt in einem dem ersten Betriebszustand vergleichbaren zweiten Betriebszustand wird eine zweite Ausgangsspannung (U0, UMPP) und/oder ein aus dieser Ausgangsspannung (U0, UMMP) abgeleiteter zweiter Parameter der Anlage (1) ermittelt. Schließlich wird eine Abweichung zwischen erster und zweiter Ausgangsspannung (U0, UMPP) und/oder zwischen erstem und zweitem Parameter ermittelt und eine Fehlermeldung ausgegeben, wenn die Abweichung einen vorgebbaren Schwellwert überschreitet.
