DC-overspanning > Generator loskopp.
Overspanning op de DC-ingang. De omvormer kan onherstelbaar beschadigd
raken.
Deze melding is tevens te herkennen aan snel knipperende led's.
Oplossing:
Schakel de omvormer onmiddellijk spanningsvrij (zie hoofdstuk10,
pagina61).
Controleer of de DC-spanning onder de maximale ingangsspanning van
de omvormer ligt. Ligt de DC-spanning onder de maximale
ingangsspanning van de omvormer, sluit de DC-connectoren dan
opnieuw op de omvormer aan.
Ligt de DC-spanning boven de maximale ingangsspanning van de
omvormer, controleer dan of de PV-generator correct geconfigureerd is
of neem contact op met de installateur van de PV-generator.
Neem contact op met de afdeling Service als deze melding vaak
optreedt (zie hoofdstuk15 "Contact", pagina98).
