Planning for Microinverter Installation
The Enphase IQ 7 Micro is compatible with 60-cell PV modules, and the IQ 7+ Micro and IQ 7A Micro
support 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
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 31 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.

* The Enphase IQ Series EN4 Bulkhead Microinverters include AC and DC connectors integrated into the
microinverter bulkhead. The AC port of the Enphase EN4 bulkhead connects to an Enphase Q Cable or
Enphase Field Wireable Connector. The DC port of the EN4 Bulkhead has been evaluated by UL for
intermatability with TE PV4-S SOLARLOK connectors and other connectors as indicated in this
document.
If your PV modules have TE PV4-S SOLARLOK connectors, or other connectors Listed and identified
for intermatability with the Enphase EN4 bulkhead connector, you may plug them directly into the IQ7
Series microinverter with EN4 bulkhead. For other connector combinations, Enphase bulkhead
adapters are required.
