this guide and the IQ Gateway Metered Installation and Operation Manual at https://enphase.com/contact/support. Safety warnings are
listed at the end of this guide.
PREPARATION
A ) Download the latest version of the Enphase Installer App
and log in to your Enphase Installer App account. With
this app, you can connect to the IQ Gateway Metered
to track system installation progress. To download, go
to https://enphase.com/installers/apps or scan the QR
code at the right.
B ) Check the box for the following items:
• IQ Gateway Metered
• Two split-core Current Transformers (CTs) for production and
consumption metering
• DIN rail for mounting
• Quick Install Guide (this document)
• EMI Line Filter
C ) Check that there is space in the switchboard to install CTs. Do not
install the CTs in a panel where they exceed 75% of the wiring space
of any cross-sectional area within the panel.
D ) Install the IQ Gateway Metered in an IP54-rated, or better enclosure
with conduit attachment when installing outdoors. Do not drill
holes on the top of the enclosure or anywhere that allows moisture
ingress. Metallic enclosures may impair Wi-Fi signal strength. Use
an appropriately rated enclosure if installing the IQ Gateway Metered
indoors.
E ) If you are installing the IQ Gateway Metered in a multi-phase applica-
tion, make sure you have the following items:
• Additional CTs (CT-100-SPLIT-ROW) for multi-phase installations.
Make sure you have one CT for each phase monitored, for both
production and consumption.
• The IQ Gateway box contains a label to identify the line on which
a CT is installed. Stick a small label denoting the line on a CT and
wrap the corresponding bigger label on the end of the lead wire
after stripping, and install the CT on the appropriate line.
• A phase coupler. If installing on a three-phase site, install a phase
coupler on the load side of the overcurrent protection device.
See the Technical Brief on Phase Coupling for your region at
https://enphase.com/contact/support. Consult Enphase Support
for compatible devices.
F ) Decide how to connect the IQ Gateway Metered to the internet:
choose to use Wi-Fi, a Mobile Connect modem, or Ethernet.
G ) Make sure you have the following optional items, if needed:
• Mobile Connect modem (order CELLMODEM-02)
• Ethernet cable [802.3, Cat5E or Cat6, unshielded twisted pair
(UTP)]. Do not use shielded twisted pair (STP) cable.
H ) Install the PV system as directed by the installation manuals.
I ) If an Enphase PV system is or will be installed at the site, create a
paper installation map to record device serial numbers and positions
in the array. Scan this map later using the Enphase Installer App and
your mobile device.
• As you did with the microinverters (and Enphase AC batteries, if in-
stalled), peel the removable label from the bottom of the IQ Gateway
Metered and afx it to the paper installation map.
• Always keep a copy of the installation map for your records.
NOTE: If needed, you can nd an installation map with any Enphase
Microinverter Quick Install Guide.
NOTE: RCD is recommended to be installed on-site for fault
protection. Follow local regulations on installing RCD on-site with
IQ Gateway and IQ Series Microinverters.

bDevice detection issues
If the Device communications LED lights are solid red, it may be a result of low
light levels. If there is not enough sunlight to power up the microinverters, they cannot
communicate with the IQ Gateway.
If there is sufcient daylight for the microinverters to power up, the issue may be that
the IQ Gateway Metered is having difculty communicating over the power lines. To
troubleshoot this issue:
• Check the Enphase Installer App to see which devices are not
communicating.
• Check that the circuit breaker(s) for the PV array are in the “ON” position.
• Verify that the PV modules are connected to the microinverters.
• Verify the PV module DC voltage is within the allowable range for the microinverter.
cPower production issues
If the Power production LED lights are solid red, check the Enphase Installer App to
see which microinverters are not producing:
• If none of the microinverters are producing power, there may be a grid or wiring
issue. First, verify that there is proper input voltage and frequency from the grid.
Next, check the breaker and wiring, starting at the switchboard.
• If all of the non-productive microinverters are on the same branch, check the
breaker and wiring starting at the junction box for the affected branch.
• If only one or scattered microinverters are not producing power, rst check to see
that the AC connectors are fully seated in the IQ Cable connectors. Next, check
that each module is providing the required startup voltage for the microinverter.
A PV module that is failing or that is undersized may not generate enough power
for AC conversion.
dInternet connection issues
If you are using Wi-Fi and the Network communications LED remains OFF:
• The WPS connection window may have timed out. Retry the connection steps.
• Make sure that the broadband router is operational by checking that other devic-
es at the site can access the network.
• Be aware that metal enclosures or obstructions impede wireless communication.
• If you cannot see your router or access point in the list on the IQ Gateway, or
cannot maintain a connection, it may be necessary to add a wireless repeater to
extend the network range.
If you are using Wi-Fi and the Network communications LED lights solid red, make sure
that the broadband router is connected to the Internet by checking that other devices
at the site can access the Internet.
If you are using the Mobile Connect modem and the Network communications LED
remains off or lights solid red, see Troubleshooting in the Mobile Connect Installation
Guide.
For any connection method, you can troubleshoot network issues with the Enphase
Installer App by tapping the Network button, then Diagnostic Tools.
If you replace the broadband router, congure the IQ Gateway Metered Wi-Fi settings
for the new Wireless Network Name (SSID) and password.

A) Before running CT wires through the conduit, use coloured tape to mark each
of the CTs and the free ends of its wires with a different colour. You can run
multiple CT wires through a single conduit.
B ) Wire the IQ Gateway Metered for power.
• Depending on the number of phases you will wire, use a one-pole, two-
pole, or three-pole (20 A maximum) circuit breaker for the supply wiring.
• Make sure the supply wiring is 2.5 mm2copper rated at 75ºC or better.
• Locate the screw on the terminal block door, and loosen it with a screw-
driver to unlock the door and ip it open.
• Connect Line 1 to L1, Line 2 to L2, Line 3 to L3, and Neutral to N, as
required.
• Tighten all connections to 0.56 N m.
C ) Install the Production CTs on phases as required:
• Locate the arrow on the CT label.
• To monitor production on Line 1:
- Connect the white wire to the “I1•” terminal and the blue wire to the “I1”
terminal.
- Clamp the CT on active Line 1 of the solar production circuit with the
arrow pointing toward the load (away from the solar array).
• To monitor production on Line 2:
- Connect the white wire to the “I2•” terminal and the blue wire to the “I2”
terminal.
- Clamp the CT on active Line 2 of the solar production circuit with the
arrow pointing towards the load (away from the solar array).
• To monitor production on Line 3:
- Connect the white wire to the “I3•” terminal and the blue wire to the “I3”
terminal.
- Clamp the CT on active Line 3 of the solar production circuit with the
arrow pointing towards the load (away from the solar array).
• Tighten all connections to 0.56 N m.
D ) Install the Consumption CTs in phases as required:
• Locate the arrow on the CT label.
• Make sure that the AC mains wire(s) are de-energised until you have
secured the CT wires in the terminal blocks.
NOTE: Only run active conductors of the same phase through each CT.
Each CT can monitor multiple active conductors.
• To monitor consumption on Line 1:
- For the rst CT, connect the white wire to “I1•” and the blue wire to “I1”.
- Clamp the CT on the main supply Line 1 (active). When the Consump-
tion CT is on Line 1 (active) conductor, the arrow must point towards the
load (away from the grid).
NOTE: Due to variance in switchboard design and main power feed, there may not always be
enough space to install CTs.
Match CT and voltage sense phases. Make sure to consistently identify all the AC lines at three
points: The main switchboard feed, the IQ Gateway, and the solar production circuit breaker. Wire
colours may not always consistently identify Lines 1, 2, and 3. If in doubt, use a multimeter to
check.
DANGER! Risk of electric shock. Always de-en-
ergise circuits before wiring for power and CTs.
DANGER! Risk of electrocution! Do not install
CTs when current is owing in the sensed
circuit. Always install CT wires in the terminal
blocks before energising the sensed circuit.
WIRING INSTRUCTION SHEET FOR EUROPE

REVISION DATE DESCRIPTION
140-00355-02 December 2023 Updated the “Installation in Europe using IQ7 Series Microinverters” section.
140-00355-01 October 2023 Initial release.
NOTE: Refer to Gateway SLDs for CT guidelines when using the IQ Gateway Metered.
Installation in Europe using IQ7 Series Microinverters
For installations in Europe using IQ7 Series Microinverters, Enphase requires the installation of an EMI Line Filter (ELF-020-1P) to prevent electromagnetic interfer-
ence (EMI) noise above permissible limits from reaching home loads and the utility grid. The device is rated for 20 A, 50 Hz, and up to 250 VAC operation.
Note that the EMI Line Filter does not improve power line communication between the gateway and the microinverters. It is for EMI noise suppression. Ensure the
EMI Line Filter is installed indoors or in an IP54 or higher rated enclosure.
To minimize noise-coupling, do not place incoming and outgoing cables of the EMI Line Filter, next to each other. To plan the installation of the EMI Line Filter, see
the following wiring diagrams.
NOTE: For three-phase systems, three EMI Line Filters must be installed on the site.
