Spannungen zwischen Plus- und Minuspol messen.
Wenn folgende Ergebnisse gleichzeitig vorliegen, liegt ein Erdschluss in der PV-Anlage
vor:
Alle gemessenen Spannungen sind stabil.
Die Summe der beiden Spannungen gegen Erdpotenzial entsprechen annähernd
der Spannung zwischen Plus- und Minuspol.
3. Wenn ein Erdschluss vorliegt, über das Verhältnis der beiden gemessenen Spannungen den
Ort des Erdschlusses ermitteln und Erdschluss beseitigen.
4. Wenn kein eindeutiger Erdschluss messbar ist und die Meldung weiterhin angezeigt wird,
Isolationswiderstandsmessung durchführen.
5. Strings ohne Erdschluss wieder an den Wechselrichter anschließen und Wechselrichter wieder
in Betrieb nehmen (siehe Installationsanleitung des Wechselrichters).
Ort des Erdschlusses
Das Beispiel zeigt einen Erdschluss zwischen dem zweiten und dritten PV-Modul.
