I have 14 inverters and panels on one breaker and 10 each on another breaker both go to 1 disconnect.
I got everything off of the roof and have isolated one m215 that does not put out any current, but it does boot up correctly.
I found some m215 on ebay for 40-60$.
I do not understand why the one array would not come online. When go back up with the system I will install a few at a time, test, install more, test, etc.
