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?
