of course it is the array on the pole barn with 61 degree roof that I had to rent a telehandler for.. figures.

Oh no!!
What is the series/parallel config for the array?
How many panels? Wattage of individual panels?
10 panels in series per array, 6 arrays, goes straight to inverter, no parallel/combiner boxes etc, 400 watt (500 with biracial) panels

Ok, so if it was open, you would get nothing. The fact that you got 1/4 kinda seems like miss wired.
If it was a bad connection I might be arcing at heating up.. Bad news.
If its a bad panel it would certainly bring the whole series string down like that.
If I were you I would disconnect the string tonight tho and inspect later. BE CAREFUL
yeah I will go and disconnect that string and see what I can figure out tomorrow. I will try swapping it into another input on the inverter tomorrow also, make sure it is not that input on the inverter itself.

Tonight just think you only connected 3 out of the 10.
I did that once. I actually shorted the other ones. Luckily no damage! Spent 3 days shorted!
Well they are all connected, when not under load/not connected to the inverter they were producing the same ~350 volts the other 5 arrays are producing.. so something is up.. I will swap inputs on the inverter first thing tomorrow and see if the problem follows, if so then I know it is something with the array and not the inverter.Tonight just think you only connected 3 out of the 10.

Well I turned the disconnect off on the problem string and the disconnect for the other array into that 6000xp and swapped them in the inverter from pv1 to pv2, turn both array disconnects back on and now both arrays are producing normal power and voltage, so very strange! I will keep an eye on it and see how it performs throughout the day, currently with complete overcast at 1:30 I am getting 2200 watts.

Very interesting

It was difficult to see in the video, but I’m wondering if the wire insulation might have been touching the MPPT, preventing a solid connection.
Yeah it could have been, it was on the center inverter as well, the one pictured there. I just swapped pv 1 and 2 around with each other and no issues all day. It must have been a bad connection somehow.. glad that is all it was, or at least seems to have been.
