Evan, I am not sure if this is the same issue, but I have seen a lot of arc fault issues with the E20-327 modules paired with SMA inverters. Every system that we have done repairs on have had the Yukita junction boxes, and there were a handful of failed solder joints on the diodes in the junction boxes. Sunpower is having contractors cut out the diodes and install an external diode per module. The issues related to this have popped up a lot in the past few years, even though the modules were installed roughly around 2015-2018.
