Hi fellows, this is George from Romania. I’ve been in solar since 7 years by now, and the last 2 years were full of BESS as well. My activity was related especially on solar inverters, transformer stations and full BESS configuration. As a first topic for this channel, I would like to share a case related to solar inverters which support only IT system configuration, but they are connected to a TN-C system (dyn11 as vectorial group for TF station for example). Such cases I met multiple times on site and found the IGBT failure. What’s your experience for such topic and how do you think you can prevent?
