Hi William, I have had a similar experience here in New Zealand on a FP2 fitted
with VFXR3024E inverters. Factory wired with a Mate3. Ran ok for around 2
months then random errors with “FX Firmware incompatible” then “FX Firmware OK”
until eventually the slave inverter shut down with a message
I think the other poster's idea that the cables could have been switched
is possible. It could explain the Master getting switched. I'm
certainly not saying a complete internal glitch wasn't it either. We've
all seen our share of those as well.

I have no reason to believe anyone has been meddling. No one knows the
password. It does look like some serious glitch.

Electrical noise coming in from the utility side
can also cause an arc fault code.

Hi Dane,
It was a few years ago, but I believe we had an arc fault with the same
type of array setup (although I'm wondering now if they were -12s - I'm
pretty sure they were -22s). After checking everything twice, we ran 1
string at a time and still got the arc fault. After badgering tech support
This array is a ground mount, so not on a roof, and no radio towers nearby.
As for grounding, The array and the shed with the interconnection point are
in the same area.
There are a couple ground rods there, which everything on the AC side is
connected to,
including a #6 wire from each inverter. t
