Planning for Microinverter Installation
The Enphase IQ 6 Micro is compatible with 60-cell PV modules, and the IQ 6+ Micro supports PV
modules with 60 or 72 Cells. Both install quickly and easily. The microinverter housing is designed for
outdoor installation and complies with the NEMA 250, type 6 environmental enclosure rating standard:
NEMA 6 rating definition: Indoor or outdoor use primarily to provide a degree of protection
against hose-directed water, the entry of water during occasional temporary submersion at a
limited depth, and damage from external ice formation
The Enphase Q Cable is available in multiple connector spacing options for landscape and portrait
orientations in 60 and 72-cell PV modules to meet varying site requirements. For Enphase Q Cable
ordering information, see “Enphase Q Cable Planning and Ordering” on page 31.
Compatibility
The Enphase IQ 6 and IQ 6+ Micros are electrically compatible with PV modules as listed in the
following table. For specifications, see “Technical Data” on page 45 of this manual. You can refer to the
Enphase Compatibility Calculator at:
enphase.com/en-us/support/module-compatibility to verify PV
module electrical compatibility. To ensure mechanical compatibility, be sure to order the correct
connector type for both microinverter and PV module from your distributor.
WARNING: Risk of fire. The PV module DC conductors must be labeled "PV Wire" or "PV
Cable” to comply with NEC for Ungrounded PV Power Systems.

Grounding Considerations
The IQ 6 Micro and the IQ 6+ Micro do not require grounding electrode conductors (GEC) or equipment
grounding conductors (EGC). 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.
