[RE-wrenches] old sanyos failing Iso test

[Kirk Herander]

I now have two systems with older Sanyos(Panasonic), circa 2004, which
consistently fail the inverter (Solaredge) startup Insolation test in wet
weather. Usually 200 - 550 kohms, just below the inverters 600k limit.
Confirmed by my meggering. I discovered this after convincing the owners to
upgrade the inverters from old SMA's which don't test for it. Anyone else
see this issue in older panels, in particular Sanyos?
