Hi All, For years I have understood that when doing a supply side connection, you are supposed to bond the neutral to ground in the solar service disconnect. I have a Midnite AIO system with two inverters (set up as a supply side connection) that recently was getting a CA-DC link Overvoltage error. When talking to Midnite, their first response was to make sure that there was only one N-G bond in the whole system. When I mentioned that the solar is a separate service and thus there is a N-G bond in both the main panel and the inverter distribution panel, they said to remove it from the inverter distribution panel. I want to make the system work right, but I also am hesitant to do something against how I have understood the NEC to be for a long time. I am curious if you all have thoughts on this or run into a similar situation.
