Ground fault [RE-wrenches]

I'm not ready to add PVGFP's to all my installs. I think that's overkill,
and not addressing the problem of adequate installation (by whoever installs
the panels).

When we install a string, we test voltage at our termination box (usually
just before we penetrate the roof) and check for proper level. Any bad
wiring, pinched connections, etc., and it shows up here. We learned to do
this after one piece of bad wiring by us, and one bad module from a
manufacturer. (backwards diode).

Lie all the other stuff we talk about here, adding components is not going
to make the system safe under any and all cases of bad installs. Same for
non-PV installs. Let's not jump on the technology fix here.
