About EN4 Bulkhead Microinverters

If your PV modules have TE PV4S SOLARLOK connectors, or other connectors Listed and identified for
intermatability with the Enphase EN4 bulkhead connector, you may plug them directly into the IQ 7 Series
microinverter with EN4 bulkhead. For other connector combinations, Enphase bulkhead adapters are
required. For models with the suffix "-E", the bulkhead connectors are evaluated for use with specific DC
connectors. See the Listed connectors in the following table:

Grounding Considerations

The Enphase Microinverter models listed in this guide do not require grounding electrode conductors
(GEC), equipment grounding conductors (EGC), or grounded conductor (neutral). Your Authority Having
Jurisdiction (AHJ) may require you to bond the mounting bracket to the racking. If so, use UL2703
hardware or star washers. The microinverter itself has a Class II double-insulated rating, which includes
ground fault protection (GFP). To support GFP, use only PV modules equipped with DC cables labeled
PV Wire or PV Cable.
