IQ7 Micro Installation

IQ 7 / IQ 7+ / IQ 7X Micro Installation and Operation

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 with connector spacing options to accommodate installation of PV

modules in portrait or landscape orientation. 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

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 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.
