The IQ Gateway
The IQ Gateway is an integral component of the Enphase Home Energy Solution. It operates
between Enphase Microinverters, or other PV system, and the Enphase Installer App™web-based
monitoring and analysis software. When used with Enphase devices, the IQ Gateway can control
grid management functions and monitor PV production and site consumption. When used with non-
Enphase PV systems, it can collect production and consumption data, but it does not control grid
management functions.
The IQ Gateway Metered uses precision Current Transformers (CTs) to measure PV production from
the solar main supply switch and home energy consumption from the AC mains.
How the Enphase Home Energy System Works
This integrated system maximises energy harvest, increases system reliability, and simplifies design,
installation, and management.
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
sophisticatedMaximum Power Point Tracking (MPPT) algorithm.
The IQ Gateway operates as a gateway between the Enphase Microinverters and Enphase Installer
App. It collects energy and performance data from the PV system over on-site AC power lines, and it
forwards that data to Enphase Installer App, via the Internet, for statistical reporting. Enphase
Installer App analyzes the data collected by each communicating device. Enphase Installer App
automatically detects any shortfall in energy production, identifies possible causes, and suggests
solutions. Enphase Installer App constantly monitors every Enphase device connected to the IQ
Gateway and is essential for system monitoring and troubleshooting.
Enphase Installer App provides a wide range of information on system performance. You can access
Enphase Installer App onyour computer or mobile device and view current performance information
at any time.

Installation Planning and Preparation
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 Installer App monitoring and
analysis website. The IQ Gateway communicates with the Enphase Microinverters and AC Batteries
using the site’s power lines.
After the IQ Gateway is installed and all devices (microinverters and/or batteries) are scanned or
provisioned, the IQ Gateway maintains an internal database of all known Enphase devices at the
site it manages. At regular intervals, the IQ Gateway polls each Enphase device for its energy data.
Using its Internet connection, the IQ Gateway then forwards that information to Enphase Installer App.
The IQ Gateway also reports any error conditions affecting itself or other Enphase devices. You can
view both energy data and errorconditions in Enphase Installer App.
The IQ Gateway incorporates power line and Internet communications functions. One "side" of the IQ
Gateway communicates with the Enphase devices through power lines at the site. The other "side" of the IQ
Gatewaycommunicates with Enphase Installer App over the Internet.

oAn iOS device running iOS 8 or later.
Box Contents
Check the shipping box for the following items:
• IQ Gateway Metered
• Current transformers (CTs): Two split core CTs, one for production and one for consumption
metering. You must order additional CTs (CT-100-SPLIT-ROW-ROW) to separately monitor
multiple phases.
• Length of DIN rail for mounting
• Ferrite bead to attach to your Ethernet Cable, if used
• IQ Gateway Quick Install Guide
Plan the Enclosure Type
Install the IQ Gateway in an IP54-rated, or better enclosure. Use an appropriately rated enclosure if
hard-wiring indoors.
Use a Phase Coupler for a Multiphase Site
If you are installing in a multiphase application, the power line communication signal must be
“coupled” between the phases to allow the IQ Gateway to communicate with all the Enphase
devices in the system.Install a phase coupler on the load side of the over-current protection device.
See the Enphase TechnicalBrief on Phase Coupling for your region at enphase.com/support or
consult Enphase support for compatible devices.
Plan the Internet Connection
To use the Enphase Installer App web-based monitoring and analysis software, additional requirements are:
• Internet connection for the IQ Gateway through a traditional router or modem or Enphase
MobileConnect (Enphase model CELLMODEM-02). Decide whether to connect the IQ
Gateway to the Internet using integrated Wi-Fi, an Enphase Mobile Connect modem, or
using a PLC bridge with Ethernet cables.

Metering CT Considerations
The IQ Gateway uses readings from CTs to report measurement data for PV energy production and
energy consumed by the home or business. When current transformers (CTs) are wrapped around a
live wire, the current going through the wire induces a current on the CTs primary internal winding,
which in turn induces a current on the CTs secondary internal winding. The current on the
secondary winding is proportional to the current on the original circuit and this is used for making
measurements. Install the CTs as shown in the wiring instruction for your region.
• Production CTs measure power production through a connection to the solar supply
main switch.
• Consumption CTs measure energy consumption through a connection to the AC mains.
To install the CTs, use a protected route in conduit for the CT wires to the IQ Gateway. Install one
split-coreCT per monitored phase for production metering and one split-core CT per monitored
phase for consumption metering. If you need to extend the CT leads (up to 148 meters), see “Extend
CT Leads, If Needed”on page 16.
Required Items
If you hard-wire the IQ Gateway outdoors, you must install it in NRTL certified NEMA type 3R (or
better) enclosure. 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.
The IQ Gateway Metered includes a production CT and a consumption CT. You must order
additional CTs (CT-100-SPLIT-ROW-ROW) for multiphase installations. Make sure you have one
CT for each phasemonitored, for both production and consumption.
Optional Items
Make sure you have the following optional items, if needed:
• Enphase Mobile Connect modem (order Enphase CELLMODEM-02)
• Ethernet over power line communication (PLC) bridge with Ethernet cables [order EPLC-02
(EU), EPLC-03 (UK) or EPLC-04 (AU/NZ) separately]
• Ethernet cable (use 802.3, unshielded Cat5E or Cat6). Do not use shielded twisted pair
(STP)cable.

3. Install CTs for Metering
The IQ Gateway Metered (ENV-S-EM-230) uses terminal blocks for power and metering connections.
NOTES:
When wiring the IQ Gateway for production and consumption metering, be sure to install the
current transformers (CTs) exactly as described for your application.
When using CTs, do not energise the PV system before the CT installation is complete.
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.
You can run more than one wire through the CT if all wires are on the same phase and they
fit the opening in the CT.
Install one split-core CT (model CT-100-SPLIT-ROW) per monitored phase for production metering
and one split-core CT (model CT-100-SPLIT-ROW) per monitored phase for consumption metering.
Use a protected route in conduit (raceway) for the CT wires to the IQ Gateway. If you need to
extend the leads (up to 148 meters, see “Extend CT Leads, If Needed”on page 16.
Preparation
a. Before running the CT wires through conduit, use coloured tape to mark each of the CTs and
thefree ends of its wires, marking each with a different colour. You can run multiple CT
wires through a single conduit.
b. When installing CTs, 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 IQ
Gateway, and the solar production circuit breaker. Wire colours may not always consistently
identify Lines 1, 2and 3. If in doubt, use a multimeter to check.

solarproduction circuit with the arrows pointing toward the load (away from the solar
array).
e. Tighten all connections to 0.56 Nm.
Install the CT for Consumption Metering (optional)
Install one split-core CT for each monitored phase to provide consumption metering. For single-phase,
connect only L1. For three-phase, connect L1, L2 and L3.
DANGER! Risk of electric shock. Always de-energise circuits before wiring power and CTs.
DANGER! Risk of electric shock. 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
install the CTas directed, making sure to connect the leads and then place the CT
around the wire and 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 theterminal blocks.
b. Take care to identify L1, L2 and L3.
c. Connect the white wire from Line 1 to “I1•” and the blue wire to “I1”.

15 Nov, 2022
16
WARNING! To extend the CT leads, the electrician must use appropriately rated, 0.75
mm2 to 2.5 mm
2
, twisted pair wire and install it in accordance with all applicable electrical
codes.
The electrician may add as much as three ohms round trip resistance to the 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
• 213 meters of 2.5 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
threeohms.
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 insulate 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.
4. If Required, Install DRM Support and a Central
The multiphase IQ Gateway Metered supports DRM (Demand Response Management). If required for
your region, an electrician can install DRM support and add a central disconnect. The IQ Gateway
(ENV-S-WM-230) has a pre-installed 15kΩ resistor that provides DRED bypass when DRED is not
required.
NOTE : In systems where a central disconnect (contactor) is installed, you must use
Installer App to configure the meters as described in Step 8 before device discovery can
complete.
To configure DRM support use the terminals shown:
