The Enphase IQ Gateway
The Enphase IQ Gateway is an integral component of the Enphase Microinverter System. It operates
between the Enphase Microinverters and the Enphase Enlighten™ web-based monitoring and analysis
software. The IQ Gateway-Monitors the microinverters that are connected to the PV modules. It
collects energy and performance data from the microinverters over on-site AC power lines, and it
forwards thatdata to Enlighten, via the Internet, for statistical reporting.
•The IQ Gateway-M uses precision Current Transformers (CTs) to measure PV productionand
home energy consumption.
How the Enphase Microinverter System Works
The Enphase Microinverter converts the DC output of the PV module into grid-compliant AC power. In
addition to performing the DC to AC conversion, it maximises energy production by using a sophisticated
Maximum Power Point Tracking (MPPT) algorithm. This integrated system maximises energy harvest,
increases system reliability, and simplifies design, installation, and management.
The IQ Gateway operates as a gateway between the Enphase Microinverters and Enlighten. The
EnphaseEnlighten web-based monitoring and analysis software analyses the data collected by each
communicating microinverter. Enlighten automatically detects any shortfall in energy production,
identifies possible causes, and suggests solutions. Enlighten constantly monitors every Enphase
Microinverter connected to the IQ Gateway and is essential for system monitoring and troubleshooting.
Enlighten provides a wide range of information on system performance. You can even access Enlighten
on your mobile device and view current performance information wherever you are.

Installation Planning and Preparation
Installation and operation of the IQ Gateway require no specialised equipment or unique computer or
networking expertise. To the Local Area Network (LAN), the IQ Gateway is just another host on the
network,much like a personal computer. The IQ Gateway simply connects to the on-site router or
Enphase Mobile Connect™ (cellular modem) for communications with the Enphase Enlighten monitoring
and analysis website. The IQ Gateway communicates with the microinverters using the site’s power lines.
After the IQ Gateway is installed and the microinverters are scanned or provisioned, it maintains an
internal database of all known Enphase Microinverters at the site it manages. At regular intervals, the IQ
Gateway polls each microinverter for its energy data. Using its Internet connection, the IQ Gateway then
forwards thatinformation to Enlighten. The IQ Gateway also reports any error conditions that affect it or
the microinverters.You can view both energy data and error conditions in Enlighten.
The IQ Gateway incorporates power line and Internet communications functions. One "side" of the IQ
Gatewaycommunicates with the microinverters through power lines at the site. The other "side" of the
IQ Gateway communicates with Enlighten over the Internet.

•Two split core current transformers (CTs) for production and consumption
•Length of DIN rail for mounting
•Enphase IQ Gateway Quick Install Guide
Plan the Power Connection
You must hard wire the IQ Gateway indoors or in an NRTL certified, NEMA type 3R (or better)
enclosure. Use an appropriately rated enclosure if hard-wiring indoors. Make sure that the site is
near the AC switchboard in which the IQ Gateway can be hardwired. Do not use a power board.
Use a Phase Coupler for a Three-Phase Site
If you are installing the IQ Gateway in a three-phase application, the power line communication signal
mustbe “coupled” between the three phases to allow the Envoy to communicate with all the
microinvertersin the system. Install a phase coupler on the load side of the over-current protection
device. See the Enphase Technical Brief on Phase Coupling for your region at enphase.com/support.
Consult Enphasesupport for compatible devices.

higher, Internet Explorer 11, Microsoft Edge for Windows, Safari 8 or higher.
Metering Considerations
The IQ Gateway-M includes a production CT and a consumption CT. When installing 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 or refer to local standards for guidance.
To install the production CT, which measures power production through a connection to the solar supply
main switch:
•Ensure there is sufficient space to install the production CT around Line (active) of the solar
supply main switch.
To install consumption CT, which measures energy consumption through a connection to the AC mains:
•For net consumption metering, ensure there is sufficient space to install the CT around Line
(active) from the main feeds.
•For total (gross) consumption metering, ensure there is sufficient space to install the CT
around the line that feed the consumption circuit.
Required Items
If you hard-wire the IQ Gateway outdoors, you must install it in an NRTL certified NEMA type 3R (or
better) enclosure with conduit attachment. Note that Metallic enclosures may impair Wi-Fi signal
strength.
Use an appropriately rated enclosure if hard-wiring indoors. Do not drill holes for conduit at the top of the
enclosure or anywhere that allows moisture ingress.
Optional Items
Make sure you have the following optional items, if needed:
•Ethernet over power line communication (PLC) bridge with Ethernet cables [order EPLC-02
(EU), EPLC-03 (UK) or EPLC-04 (AU) separately]
•Ethernet cable (use 802.3, unshielded Cat5E or Cat6). Do not use shielded twisted pair
(STP) cable.
Create the Map and Install the PV Modules and Microinverters
Create the map and install the PV modules and microinverters. You will scan this map later using
Installer Toolkit and your mobile device. (See “Method A: Provision Microinverters with Installer Toolkit”
on page 18.)
NOTE: If needed, you can find an installation map at the back of any Enphase Microinverter
manual.
•Create a paper installation map to record microinverter serial numbers and positions in the
array. Peel the removable serial number label from each microinverter and affix it to the
respective location on the installation map.
•Peel the removable label from the bottom of the IQ Gateway and affix it to the installation map.
•Always keep a copy of the installation map for your records.

Install the CT for Consumption Metering (optional)
Install one split-core CT to provide consumption metering. Create a protected route with conduit for the
CT wires to the IQ Gateway.
DANGER! Risk of electrocution! CTs must be installed with no current flowing in the sensed
circuit. Always install CT wires in the terminal blocks before energising the sensed circuit.
DANGER! Risk of electric shock. Be aware that installation of this equipment includes risk of
electric shock. If you wire the IQ Gateway at the sub-board, always de-energise the sub-
board before beginning wiring. If it cannot be de-energised, a qualified electrician may safely
installthe CT as directed, making sure to connect the leads and then place the CT around
the wireand latch.
WARNING! Do not install the CT in a panel where they exceed 75% of the wiring space of
any cross-sectional area within the panel or refer to local standards for guidance.
a. Make sure that the AC mains wire(s) are de-energised until you have secured the CT wires in the
terminal blocks.
b. Connect the white wire to “IA•” and the blue wire to “IA”.
c. Clamp the CT on the solar supply Line (active). When the consumption CT is on the line (active)
conductor, the arrow should point toward the load. Unlatch the CT and place Line (active) in
through the opening. Latch the CT and listen for the click as it closes.
NOTE: Only run active conductors through the CT. The CT can monitor multiple active
conductors.
d. Tighten the terminal block screws to 0.56 Nm.
Extend Consumption CT Leads, If Needed
If needed, an electrician may extend the leads of the consumption CT using the following guidance:
WARNING! To extend the CT leads, the electrician must use appropriately rated, 0.75mm2
to 1.5mm2, twisted pair wire and install it in accordance with all applicable electrical codes.
NOTE: Be advised that this step applies only to the IQ Gateway-M (model ENV-S-WM-230
or ENV-S-AM1-230-60) and not to the IQ Gateway Standard (model ENV-S-WB-230). The
terminal block on EnvoyS Standard cannot be used for metering and as these connections
are not internally complete in the IQ Gateway Standard and cannot provide metering
features.
The electrician may add as much as three ohms round trip resistance to the consumption CT or up to 1.5
ohms per wire. For reference, the following maximum lengths at 75° C by gauge are:
•64 meters of 0.75 mm2 7-strand Cu = 1.5 ohms
•85 meters of 1 mm2 7-strand Cu = 1.5 ohms
•128 meters of 1.5 mm2 7-strand Cu = 1.5 ohms
Resistance figures may not be appropriate for all geographies or installation conditions. A qualified
electrician must determine the wire gauge and type to obtain a maximum round trip resistance of three
ohms.
Select wire that is code type and rated for voltage and temperature for the specific application.
Mechanically protect the wires in a code type conduit or raceway. Use certified connectors for splices
and insulated splices from one another and from the raceway, conduit, or junction box, if metallic.
Buried wires must be certified for direct burial and follow the code for installation. Do not bury splices
unless in a certified junction box rated for the application and use a certified moisture resistant
connection method.

microinverters. On the Overview screen, check that the new profile is set on all the microinverters. This
may take up to 5 minutes.
c. Set up metering for the IQ Gateway-M (model ENV-S-WM-230 or ENV-S-AM1-230-60):
• Tap the Meters button and check that Production Metering is enabled.
• If you installed consumption metering CTs, tap the > to the right of Consumption Meter.
−If the circuit that passes through the consumption CTs includes load with solar production, leave
the type set to Net.
−If the circuit that passes through the consumption CTs includes load only, change the type to
Total (Gross).
• Tap Enable Consumption Meter.
• Return to the Overview screen and verify the meter reading(s).
WARNING! If using consumption metering, be sure to set the meter type correctly. You
cannot change this setting once the meter is enabled.
NOTES:
•Net metering considers the generation of the PV system and the household’s
consumption and calculates the net outcome.
•Total or gross metering measures the entire output of your system separate from
your electricity consumption.
If you used Installer Toolkit to detect microinverters, the Power Production LED lights solid green when
all expected microinverters are producing power. If you did not use Installer Toolkit, it lights solid green if
all communicating microinverters are producing power. It flashes green when microinverters are
upgrading. Check Installer Toolkit for production status details. If the Power Production LED remains
solid red, see “Issue: Installer Toolkit Indicates that Scanning is Inhibited ”on page 35.
8. Connect to Enlighten
The IQ Gateway requires a connection to the Internet for reporting to Enlighten. You can provide this
connection through an existing broadband router, other Wi-Fi access point at the installation site, or by
using the Enphase Mobile Connect cellular modem.
WARNING! Risk of Equipment Damage. Do not remove power from the IQ Gateway if the
LEDsare flashing green. This indicates that a software upgrade is in progress.
Connect to a broadband router using one of these methods, described in the following sections:
•Method A: Integrated Wi-Fi
•Method B: Enphase Mobile Connect (order CELLMODEM-02 separately)
•Method C: Ethernet cable (not included, installer must provide). This method requires that you

use the ferrite bead included with the IQ Gateway.
•Method D: Power Line Communication Bridges [order EPLC-02 (EU), EPLC-03 (UK) or EPLC-04
(AU) separately]. This method requires that you use the ferrite bead included with the IQ
Gateway.
Method A: Integrated Wi-Fi
The IQ Gateway integrated Wi-Fi operates at both 2.4GHz and 5GHz and supports several wireless
securityprotocols in addition to Wi-Fi WPS. These include WEP Open System, WEP Shared Key, WPA-
PSK, WPA2-PSK, WPA-EAP, and WPA2-EAP.
To use the Enphase integrated Wi-Fi, you need a wireless
router.
a. On the IQ Gateway, verify that no Ethernet
cable isplugged into the RJ45 port.
b. If your router supports WPS, press and hold the
WPS button on the wireless router for a few
seconds. On most routers, a WPS LED begins flashing.
c. If you are using the Installer Toolkit mobile app, go to your system and tap Installer Toolkit Step 4
(Envoy connectivity), tap Wi-Fi, and then tap your Network from the list of available networks. If the
wireless router does not support WPS, you may be prompted to enter a password.
If you are not using the Installer Toolkit mobile app, you can only connect using WPS. Initiate a
WPS connection by pressing and holding the AP Mode button for 5 seconds.
The Network Communications LED begins flashing green. Within three minutes the Network
Communications LED lights solid green, indicating a successful connection to the Internet and to
Enlighten. If the Network Communications LED remains off or lights solid red see “Internet
Connection Issues” on page 36.
Method B: Ethernet Cable
To use this method, you need an Ethernet cable and a broadband router. To install the cable and ferrite
bead:
a. Select a Cat5E or Cat6 Ethernet cable unshielded twisted pair (UTP). Do not use shielded
twisted pair (STP) cable.
b. Place a ferrite bead on the new cable, near one end, and close the latch.
c. Plug the cable end with the ferrite into the IQ Gateway Ethernet port.
d. Secure a cable tie on the cable on each side of the ferrite bead.
e. Tighten an additional cable tie around the ferrite bead.
f. Trim any cable tie excess.
g. Plug the other end of the Ethernet cable into the network

Within two minutes the Network Communications LED lights solid green, indicating a successful
connection to the Internet and to Enlighten.
When you use Ethernet cable, two small LEDs on the Ethernet port indicate Ethernet link and activity.
The link LED is solid green when the cable is connected correctly, and the activity LED flashes green or
yellow when data is sent or received.
Method C: Power Line Communication Bridges
Order EPLC-02 (EU), EPLC-03 (UK) or EPLC-04 (AU) separately.
If you need to locate the IQ Gateway away from the router, at a distance where an Ethernet cable is not
practical, or the wireless signal does not reach, use power line communication bridges with the IQ
Gateway.Bridges allow the IQ Gateway to communicate with the broadband router over the site’s power
lines. To install power line communication bridges:
a. Plug one of the bridges into the same AC socket that the IQ Gateway is using.
b. Place the bead on the cable, near one end, and close the latch.
c. Plug the cable end with the ferrite into the IQ Gateway Ethernet port.
d. Secure a tie wrap on the cable on each side of the ferrite bead.
e. Tighten an additional tie wrap around the ferrite bead.
f. Trim any tie wrap excess.
g. Plug the other end of the Ethernet cable into the bridge.
h. Plug the other bridge into an AC socket near the broadband router.
i. Connect one end of a second Ethernet cable to the second bridge and connect the other end of
the Ethernet cable into the broadband router.
Within two minutes the Network Communications LED lights solid green, indicating a
successful connection to the Internet and to Enlighten.
If the Internet Connection Fails
After using any of these connection methods, if the IQ Gateway does not connect to the Internet within
fiveto ten minutes after you attempt a connection, see “Internet Connection Issues”on page 36.
9. Send System Summary Report
When you have completed your system setup, you can generate and email a summary report.
a. From Installer Toolkit, tap step 7 of the system workflow to view the report. The report displays Envoy
and system information with a list of device serial numbers, their last power reports, and information
about the grid profile applied to the microinverters.
b. Tap to email the report as needed as a record of successful system installation and for evidence of
grid profile settings.
NOTE: If your mobile device is connected to the Envoy using AP mode, the email stays in
the email outbox to be sent when the mobile device reconnects to the Internet. To disconnect
from the Envoy network, go to Settings on your mobile device and disconnect from the IQ
Gateway Wi-Fi network “Envoy_nnnnnn” (where “nnnnnn” represents the final six digits of
theEnvoy serial number).
NOTE: If you connect to an Envoy after associating it to a system, the report includes a
system name and address. For more information, refer to the Enphase Installer Toolkit
