enphase IQ8 Series Quick Install Manual

Q U I C K I N S T A L L G U I D E
Install IQ8 Series Microinverters with integrated MC4 connectors
To install IQ8 Series Microinverters, read and follow all warnings and instructions in this guide and in the IQ8 Series Microinverters Installation and
Operation Manual at: https://enphase.com/en-gb/installers/resources/documentation. Safety warnings are listed on the back page of this guide.
IMPORTANT: The IQ8 Series Microinverters include both AC and DC connectors integrated into the bulkhead. The AC port connects to IQ Cable or
Enphase Field Wireable connector. The DC port has been evaluated by TUV for intermateability with Stäubli made MC4 connectors, whose cable
coupler models are "PV-KST4/...-UR, PV-KBT4/...-UR, PV-KBT4-EVO2/...-UR, and PV-KST4-EVO2/...-UR". The DC port of the inverter must be mated
with Stäubli made MC4 connectors.
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. Refer to local electrical codes and standards for grounding requirements of PV array and racking.
IQ8 Series Microinverters require the IQ Cable. An IQ Gateway is required to monitor performance of the IQ8 Series Microinverters.
NOTE: 1) After you log in to your Enphase account from Enphase Installer App, scan the microinverter serial numbers (standard 1D bar code) and connect
to the IQ Gateway to track the system installation progress. Please ensure you are using the latest version of Enphase Installer App 3.28 (3.28.0 and above).
2) Installer must check the manufacturing date of the products to ensure that the installation date is within one year of the manufactured date of the
products. Contact your local distributor to validate the date code.
PREPARATION
A ) Download the Enphase Installer App and open it to log in to your
Enphase Installer Portal account. With this app, scan microinverter serial
numbers (standard 1D bar code) and connect to the IQ Gateway to track
system installation progress. To download, go to
installers/apps or scan the below QR code:
Android iOS
B ) Refer to the following table and check PV module compatibility at:
UK: https://enphase.com/en-gb/installers/microinverters/calculator
ANZ: https://enphase.com/en-au/installers/microinverters/calculator
You can check the intermateable cable coupler models of Stäubli made

* 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 electrical parameters including the
Bifacial gain, are within the allowable microinverter input parameters range. In
evaluating the amount of Bifacial gain, follow the recommendations of the module
manufacturers.
** IQ8MC is not available for ANZ, South Africa and India.
*** IQ8AC is not available for South Africa and India.
C ) In addition to the PV modules, racking and Enphase microinverters you
will need these Enphase items:
An IQ Gateway (model ENV-S-EM-230 or ENV-S-WM-230 or ENV-
•
S-WB-230) is required to monitor solar production and required to
propagate a grid profile to the microinverters
IQ Relay, single-phase (Q-RELAY-1P-INT) or IQ Relay, multi-phase
•
(Q-RELAY-3P-INT). For Italy region, use IQ Relay (Q-RELAY-2-3P-ITA or
IQ-RELAY-2-3P-ITA) for both single-phase and multi-phase application.

The mutli-phase IQ Relay also provides phase coupling to allow
•
microinverters on all phases to communicate with the IQ Gateway.
Use a Phase Coupler (LPC-01) for multi-phase system for phase
coupling if IQ Relay is not installed in the multi-phase system.
NOTE: In Germany only, for PV systems greater than 30 kVA, an
off-the-shelf DIN VDE V 0124-100 compliant central protection relay
must be added to the system.
