System Grounding vs. Equipment Grounding
To fully understand PV system grounding, it is essential to first differentiate between system grounding and equipment grounding.
System grounding requires a Grounding Electrode Conductor (GEC), which connects the current-carrying circuit to ground, including:
the negative or positive of a DC array
the neutral of a split single-phase AC system
the neutral of a bi-polar DC system
Equipment grounding requires an Equipment Grounding Conductor (EGC), also known as bonding, which connects all non-current carrying metal parts to ground, including:
metal enclosures
racking
module frames
With Enphase Microinverters, the EGC is bundled into the Engage Cable wiring system, which forms a ground connection with the enclosure of the microinverter. Plus, Enphase Microinverters with Integrated Ground do not require a GEC because the unit physically isolates the DC circuit within the microinverter from ground, thus meeting the NEC requirements for Ungrounded Photovoltaic Power Systems described under section 690.35.
