Planning for Microinverter Installation

The Enphase IQ8 Micro is compatible with 60-cell PV modules, and the IQ8+, IQ8M, IQ8A and IQ8H Micro
support PV modules with 60-cell or 66 cell or 72 cell in both full and split cell configuration. All of them installs
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 IQ Cable is available with connector spacing options to accommodate installation of PV modules in
portrait or landscape orientation. For Enphase IQ Cable ordering information, see "Enphase IQ Cable Planning and
Ordering" on page 30.

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 32 of this manual. You can refer to the Enphase Compatibility
Calculator at: enphase.com/en-us/support/module-compatibility
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.
