Jay,
If there is a PV ground fault, putting a short across the fuse holder
may cause damage by drawing an arc. Use a multimeter to measure voltage
across the fuse holder (should be the same as measuring voltage between
PV negative and ground); if there is no voltage then there probably
isn't
Question about the fuses. For testing could you put a short test wire across the ends of the fuse holder and use a clamp on to test for current? Would it cause any damage?Instead of potentially going through lots of fuses? JayOn Jan 19, 2025, at 7:48 AM, Mac Lewis via RE-wrenches wrote:Hello Dan
Hello Dana,
Ground faults are tricky. Here is how I would tackle this on a sunny day:
1. Visual inspection of array, looking for backsheet, wire damage, broken
glass, critter stuff (nests and bite marks). Look for water intrusion or
evidence that water has been somewhere that it shouldn't.
2.
Yes I have 2 FM100s

Do you have multiple FM 100s? If so only one should have the GFI fuse.
Broken panel with water getting into glass?
Turn it off and wait 5 min and turn
John have u recently upgraded firmware. This has been an issue w/ the
Schneider XWpro inverters off grid applications. Probably not an issue here
but FYI. As for transformers
Sola volt is what I usually use but Tformers are not too smart. Tump
