[RE-wrenches] Sunpower connectors

[Dave Tedeyan]

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.

Cheers,
Dave
