Sichere PV-Anlagen: Fraunhofer ISE testet Lichtbogendetektoren

(PresseBox) (Freiburg, )
Das Fraunhofer-Institut für Solare Energiesysteme ISE hat einen einzigartigen modularen Prüfstand entwickelt, an dem Photovoltaik-Wechselrichter mit integrierten Lichtbogendetektoren getestet werden. Diese im Wechselrichter integrierten Warnsysteme erhöhen die Sicherheit von Solaranlagen, da sie bei Lichtbögen automatisch stromlos schalten. Mit der nun veröffentlichten inter-nationalen Norm IEC 63027 sollen die Detektoren noch zuverlässiger und realitätsnaher getestet werden. Das Fraunhofer ISE war auch an der Entwicklung der Prüfnorm beteiligt, die am 3.Mai 2023 erschienen ist.

Serielle Lichtbögen in PV-Anlagen entstehen als Folge von Kontaktproblemen, z.B. durch fehlerhafte Lötstellen im Modul oder in der Gleichstromverdrahtung des Wechselrichters. Die hohen Temperaturen an fehlerhaften Kontaktstellen können im Srigcfayh rvr Xjpfk jml Glumnv frhsgc.
