[RE-wrenches] SunPower AC Modules non-Enphase

[Jamie Elmlinger]

Hey Jason,
I think I can confirm a couple of things, but I'll include the spec sheet
for you as well.
That micro is just a white labeled Enphase. Believe it or not they are
still being installed today.
So if it's the same module I think it is, you can install them just like
normal.  However, the tricky part is module thickness, you can't use the
new Ironridge stopper sleeve and you have to find the matching stopper
sleeve to go with a UFO that supply has dwindled on.  I haven't found any
other mids and ends to accommodate.  I know Pegasus is working on it.
Hope this helps.
