Q U I C K I N S T A L L G U I D E
Installing Enphase IQ 7, IQ 7+ IQ 7X and Microinverters
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+ Microinverter
Installation and Operation Manual at: . Safety warnings are listed on the back of this guide.enphase.com/support
The Enphase Microinverter models listed in this guide do not require grounding electrode conductors (GEC) or equipment grounding conductors (EGC).
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 or .PV Wire PV Cable
IMPORTANT: Enphase IQ Series Microinverters require the Q Cable and are not compatible with previous Enphase cabling. An Envoy-S is required
to monitor performance of the IQ Microinverters. The Q Accessories work only with Enphase IQ Series Microinverters.
D ) Check that you have these other items:
• An AC junction box.
• Tools: screwdrivers, wire cutter, voltmeter, torque wrench,
sockets, and wrenches for mounting hardware
• Field Wireable Connectors (Q-CONN-R-10M and Q-CONN-R-10F
for single phase Q Cable or Q-CONN-3P-10M and Q-CONN-
3P-10F for multiphase Q Cable): optional male and female
connectors.
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). For
multiphase installations, use a 3-pole 20A OCPD.

Multiphase 48 39 36
* 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. Refer to the
Voltage Rise Technical Brief at for more enphase.com/support
information.
Center-feed the branch circuit to minimize voltage Best practice:
rise in a fully-populated branch.

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 Envoy-S to track system installation
progress. To download, go to or enphase.com/toolkit
scan the QR code at right.
B ) Refer to the following table and check PV module compatibility at:
enphase.com/en-us/support/module-compatibility.
Model DC connector PV module cell count
IQ7-60-2-INT MC-4 locking type Pair only with 60-cell modules.
IQ7PLUS-72-2-INT MC-4 locking type Pair with 60- or 72-cell modules.
IQ7X-96-2-INT MC-4 locking type Pair only with 96-cell modules.
C ) In addition to the Enphase Microinverters, PV modules and racking,
you will need these :Enphase items
• An Enphase Envoy-S (model ENV-S-WM-230 or ENV-S-WB-230-F/G/I)
communications gateway is required to monitor solar production and
may be required to propagate a grid prole to the microinverters.
NOTE: Depending on your region, IQ Series Microinverters may not
produce until an Envoy-S is installed and congured with the appropri-
ate grid prole. See the Envoy-S Quick Install Guide for details.
• Enphase Q Relay, single phase (Q-RELAY-1P-INT) or Enphase Q Relay,
multiphase (Q-RELAY-3P-INT).
• Tie wraps or cable clips (ET-CLIP-100) - works with both multiphase
and single-phase cable
• Enphase Sealing Caps (Q-SEAL-10): for any unused connectors on
the Enphase Q Cable
• Enphase Terminator (Q-TERM-R-10 for single phase or Q-TERM-
3P-10 for multiphase): one for each AC cable segment end.
• Enphase Disconnect Tool (Q-DISC-10)
• Enphase Q Cable for single-phase or multiphase:
