Folks,
I have an Enphase D380 micro inverter sitting on my workbench (such as
it is).
With my ohm meter I can detect continuity between the chasis and the
AC equipment ground pin, between the chasis and the DC- pin, and
between the AC equipment ground pin and DC- pin.
My assumption is that each of these three is electrically identical
and solidly connected inside the inverter. But, I don't know.
The folks at Enphase tech support will not tell me whether or not this
is true.
Anyone out there have any ideas about this?
I believe those inverters may have internal Ground Fault Protection and
would connect, at least,
the DC negative to Chassis (earth) ground via a resettable (hopefully
resettable) fuse.
One could measure this if they knew what they were doing.
Not sure about the AC side continuity.
