A PV array (just the array) that is ground-fault device protected is not grounded except when intentionally testing (tripping) the ground-fault device.

During normal operation, i.e., a no-ground-fault-present mode, the PV
array(s) are grounded.  That is, the negative conductor is connected to
ground, right?  Or am I not understanding you properly, Joel?

aloha,
marco

"Residential roof-mounted PV arrays are ground-fault protected per Article
690.5 so they are floated ungrounded."
