#81 - Photovoltaikanlage - Einsatz nach Wochenende - Strangstromabweichungen - GAK - NH Sicherung

I received an error message from the monitoring system for our photovoltaic systems – error code "String current deviations on multiple measuring channels of a generator junction box (GAK)" – so let's troubleshoot – including an overview of the monitoring system. I expressly point out that work on electrical systems may only be carried out by qualified electricians, as required by law. I assume no liability for the technical, legal, or safety-related accuracy of the content in this video.
