Glenn,
I don't know if this may help About 7 months ago I also
replaced 2 SWR2500's with a SB5000TL. Sunwise PVs, system installed
about 10 years ago. Just FYI I have had no issues with AFCI however,
these are installed on a comp roof, DC behind the PVs is USE-2 to the
adjace

If you read some of the proposed changes for the 2017 NEC, it is looking life

Be nice William ;-)
Hi Gary,
DC can not be transformed without converting it to AC first then back to DC
again. Probably not feasible to do while tracking the MMP.

In most cases the modules have the thick double insulated whips, now with
some of the older trinas we replaced the whips as they as field
serviceable, as I recall the sharps have not been a problem. there can be
an issue when we get to the old Jbox hard wire systems
