Planning for Microinverter Installation
The Enphase IQ 7 Micro is compatible with 60-cell PV modules, and the IQ 7+ Micro supports PV
modules with 60 or 72 Cells. The IQ 7X requires a 96-cell PV module. All of them 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 28.
Compatibility
The Enphase IQ Series Micros are
electrically compatible
with PV modules as listed in the following
table. For specifications, see
“Technical Data” on page 30 of this manual. You can refer to the Enphase
enphase.com/en-us/support/module-compatibility
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 Series Micros 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.
