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) for multi-phase installations. Make
sure you have one CT for each phase monitored, for both produc-
tion and consumption.
• 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.

bDevice detection issues
If the Device Communications LED lights solid red, it may be a result of low light
levels. If there is not enough sunlight to power up the microinverters, they can’t com-
municate with the IQ Gateway.
If there is sucient daylight for the microinverters to power up, the issue may be that
the IQ Gateway Metered is having di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 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 Engage Cable connectors.
Next, check that each module is providing the required startup voltage for the
microinverter (minimum start up voltage of the microinverter being installed). 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 Enphase Mobile Connect modem and the Network Communica-
tions LED remains off or lights solid red, see Troubleshooting in the Enphase 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.

WIRING INSTRUCTION SHEET FOR INDIA
The IQ Gateway Metered uses terminal blocks for power and metering connections. Wire these terminal blocks as described in the following.
You will need to install one split-core CT per monitored phase for production metering and one split-core CT per monitored phase for consumption metering.
Use a protected route in conduit (raceway) for the CT wires to the IQ Gateway Metered. If you need to extend the leads (up to 200 meters), refer to the Enphase IQ Gate-
way Metered Installation and Operation Manual at: https://enphase.com/contact/support.
DANGER! Risk of electric shock. Always de-energise 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.
A) Before running the CT wires through conduit, use coloured tape to
mark each of the CTs and the free ends of its wires, marking each
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-, two-,
or three-pole (20 A maximum) circuit breaker for the supply wiring.
• Make sure supply wiring is 2.5 mm2copper rated at 75ºC or better.
• Locate the screw on the terminal block door, and loosen it with a
screwdriver 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 on 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
Consumption CT is on Line 1 (active) conductor, the arrow
must point towards the load (away from the grid).
• To monitor consumption on Line 2:
- For the second CT, connect the white wire to “I2•” and the
blue wire to “I2”.
- Clamp the CT on the main supply Line 2 (active). When the
Consumption CT is on Line 2 (active) conductor, the arrow
must point towards the load (away from the grid).
• To monitor consumption on Line 3:
- For the third CT, connect the white wire to “I3•” and the blue
wire to “I3”.
- Clamp the CT on the main supply Line 3 (active). When the
Consumption CT is on Line 3 (active) conductor, the arrow
must point towards the load (away from the grid).
•Tighten all connections to 0.56 N m.
NOTE: Because of variance in switchboard design and main power
feed, there may not always be enough space to install CTs.
NOTE: It is important to match CT and voltage sense phases. Be
sure to consistently identify all the AC lines at three points: the main
switchboard feed, the Envoy, 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.
E ) Install DRM support and a central disconnect as required for Aus-
tralia. The multi-phase IQ Gateway Metered gateway supports DRM
(Demand Response Management). The IQ Gateway Metered (ENV-
S-WM-230 ) has a pre-installed 15 kΩ resistor that provides DRED
bypass when DRED is not required.
NOTE: In systems where a central disconnect (contactor) is installed,
you must congure the meters as described in Step 6 before device
discovery can complete.

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.
NOTE: Because of variance in switchboard design and main power
feed, there may not always be enough space to install CTs.
NOTE: It is important to match CT and voltage sense phases. Be
sure to consistently identify all the AC lines at three points: the main
switchboard feed, the Envoy, 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.
D ) Install the Consumption CTs on 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
Consumption CT is on Line 1 (active) conductor, the arrow must
point towards the load (away from the grid).
• To monitor consumption on Line 2:
- For the second CT, connect the white wire to “I2•” and the blue
wire to “I2”.
- Clamp the CT on the main supply Line 2 (active). When the
Consumption CT is on Line 2 (active) conductor, the arrow must
point towards the load (away from the grid).
• To monitor consumption on Line 3:
- For the third CT, connect the white wire to “I3•” and the blue wire
to “I3”.
- Clamp the CT on the main supply Line 3 (active). When the
Consumption CT is on Line 3 (active) conductor, the arrow must
point towards the load (away from the grid).
•Tighten all connections to 0.56 N m.
E ) Install DRM support and a central disconnect as required for Aus-
tralia. The multi-phase IQ Gateway Metered gateway supports DRM
(Demand Response Management). The IQ Gateway Metered (ENV-
S-WM-230 ) has a pre-installed 15 kΩ resistor that provides DRED
bypass when DRED is not required.
NOTE: In systems where a central disconnect (contactor) is installed,
you must congure the meters as described in Step 6 before device
discovery can complete.
