[RE-wrenches] Re-mounting a legacy Grid-tied system, after re-roofing

[Howie Michaelson]

Hi All,
I think I know the answer to this, but wasn't 100% sure:

I have a potential client who had roof mounted grid-tied panels (Sun Power
205s, and Sun Power Inverter) and a Sunny Island for backup (batteries are
currently flat, so don't know if either they are recoverable or if the SI
is working).

Before the current owner moved in a few months ago, the panels and racking
were removed (maybe a year ago), seemingly for a reroofing.  No pictures
appear to exist of how or where they were mounted and I believe the racking
has disappeared (I have not been to this location, just have info from the
current owner and a report commissioned by the owner from a somewhat
knowledgeable energy consultant). The owner wants the panels remounted and
the SI restored to operation.

My question is can I reuse the existing equipment (no RSD) as this appears
to be a maintenance procedure, or do I need to bring the system up to
current code?  No permits will need to be pulled and there are essentially
nor AHJs involved (this is a rural site), so any adherence to code would be
for covering my a-- and making sure things were safe.  So can I, by code,
remount this system (with new racking) somewhere on the same roof, without
changing out the inverter?

I realize this might have a variable answer, but looking for the basic.

Thanks,
Howie
