Abstract

Die Erfindung betrifft ein Verfahren zur Trennung von Photovoltaikmodulen (6) einer Photovoltaikanlage von einem Wechselrichter (1) und einem Wechselrichter (1) zur Umwandlung in einer in Photovoltaikmodulen erzeugten Gleichspannung (UDC) in eine Wechselspannung (UAC) mit Zuleitungen (11, 12) zur Verbindung mit den Photovoltaikmodulen (6), wobei eine durch mechanische Trennelemente (16) in den Zuleitungen (11, 12) gebildete Trennschaltung (14) zur Trennung der Photovoltaikmodule (6) vom Wechselrichter (1) vorgesehen ist. Zur einfachen Trennung von Photovoltaikmodulen (6) auch mit besonders hohen Gleichspannungen ohne den Einsatz entsprechend aufwändiger Lastschalter ist zur Entlastung des Ausschaltvorganges der mechanische Trennelemente (16) beim Trennen der Photovoltaikmodule (6) zumindest ein Entlastungskondensator (17) vorgesehen.
