QUICK INSTALL GUIDE
Install the Enphase IQ8 Series Microinverter
To install Enphase IQ8 Series Microinverters, read and follow all warnings and instructions in this guide and in the Enphase IQ8 Series 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 IQ8 Series Microinverters require the IQ Cable. An IQ Gateway is required to monitor performance of the IQ Microinverters. The Q
Accessories work only with Enphase IQ8 Series Microinverters.
Note: After you log in to your Enphase Installer Platform account from Enphase Installer app, Scan the microinverter QR code and connect to the
Enphase IQ Gateway to track the system installation progress.
D ) Check that you have these other items:
•
AC junction box.
•
Tools: screwdrivers, wire cutter, voltmeter, torque wrench, sockets,
and wrenches for mounting hardware
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* IQ8 Series Microinverters per AC branch circuit (sin-
gle-phase)
IQ8 (240V) IQ8+ (240V) IQ8M (240V)
16 13 11
IQ8A (240V) IQ8H (240V) IQ8H (208V)
11 10 9
* 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 IQ
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.
PREPARATION
A ) Download the Enphase Installer App and open it to log
in to your Enphase Installer Platform account. With this
app, scan the microinverter QR code and connect to
the Enphase IQ Gateway 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.

IQ8PLUS-72-2-US
IQ8M-72-2-US
IQ8A-72-2-US
MC-4 locking type Pair with 60 cell / 120-half-cell, 66
cell, or 72 cell / 144-half-cell
IQ8H-240-72-2-US
IQ8H-208-72-2-US
MC-4 locking type Pair with 60 cell /120-half-cell, 66
cell, or 72 cell / 144-half-cell
* Enphase IQ8 Series Microinverters are compatible with bi-facial PV modules if
the temperature adjusted electrical parameters (maximum power, voltage and
current) of the modules, considering the front side electrical parameters (i.e., 0%
back side gain), are within the allowable microinverter input parameters range.
C ) In addition to the Enphase Microinverters, PV modules and racking,
you will need these Enphase IQ8 Series Microinverters:
• Enphase IQ Gateway (model ENV-IQ-AM1-240) communications
gateway or Enphase IQ Combiner (check enphase.com for models):
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 IQ Cable
• Enphase Terminator (Q-TERM-10): one needed at the end of each
AC cable segment
• Enphase Disconnect Tool (Q-DISC-10)
• Enphase IQ Cable:
