Installation Guide
QUICK INSTALL GUIDE
Install the Enphase IQ 7A Microinverter
To install Enphase IQ Series Microinverters, read and follow all warnings and instructions in this guide and in the Enphase IQ 7 and IQ 7+ and IQ 7X
Microinverter Installation and Operation Manual at: enphase.com/support. Safety warnings are listed on the back page of this guide.
The Enphase Microinverter models listed in this guide do not require grounding electrode conductors (GEC), equipment grounding conductors (EGC), or
grounded conductor (neutral). The microinverter 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.
IMPORTANT: Enphase IQ Series Microinverters require the Q Cable and are not compatible with previous Enphase cabling. An IQ Envoy is required to
monitor performance of the IQ Microinverters. The Q Accessories work only with Enphase IQ Series Microinverters.
E ) Protect your system with lightning and/or surge suppression devices. It
is also important to have insurance that protects against lightning and
electrical surges.
F ) Plan your AC branch circuits to meet the following limits for maximum
number of microinverters per branch when protected with a 20-amp
over-current protection device (OCPD).
Maximum*

IQ 7A Micros
(208V single phase)
11
* Limits may vary. Refer to local requirements to dene the number of
microinverters per branch in your area.
G ) Size the AC wire gauge to account for voltage rise. Select the correct
wire size based on the distance from the beginning of the Enphase Q
Cable to the breaker in the load center. Design for a voltage rise total
of less than 2% for these sections. Refer to the Voltage Rise Technical
Brief at
enphase.com/support for more information.
Best practice: Center-feed the branch circuit to minimize voltage rise
in a fully-populated branch. Using the Q Aggregator is a convenient way
to do this.
PREPARATION
A ) Download the Enphase Installer Toolkit mobile app and
open it to log in to your Enlighten account. With this app,
you can scan microinverter serial numbers and connect
to the Enphase IQ Envoy to track system installation
progress. To download, go to enphase.com/toolkit or
scan the QR code at right.
B ) Refer to the following table and check PV module electrical compati-
bility at: enphase.com/en-us/support/module-compatibility.

Pair with 60- or 72-cell modules
C ) In addition to the Enphase Microinverters, PV modules and racking,
you will need these Enphase items:
• Enphase IQ Envoy (model ENV-IQ-AM1-240) communications
gateway or IQ Combiner (model X-IQ-AM1-240-B, X-IQ-AM1-240-2,
X-IQ-AM1-240-3, X-IQ-AM1-240-3C): is required to monitor solar
production.
• Tie wraps or cable clips (Q-CLIP-100)
• Enphase Sealing Caps (Q-SEAL-10): for any unused connectors on
the Enphase Q Cable
• Enphase Terminator (Q-TERM-10): one needed at the end of each
AC cable segment
• Enphase Disconnect Tool (Q-DISC-10)
• Enphase Q Cable:
