To install the Enphase Envoy-S Metered™ gateway with integrated meter, read and follow all warnings and instructions in this Guide

and in the Enphase Envoy-S Installation and Operation Manual at: enphase.com/support. Safety warnings are listed on the back of

this guide.

PREPARATION

A ) Download the latest version of the Enphase Installer

Toolkit mobile app and open it to log in to your Enlighten

account. With this app, you can connect to the Envoy-S

to track system installation progress. To download, go to

enphase.com/toolkit or scan the QR code at right.

B ) Check the box for the following items:

•Enphase Envoy-S Metered gateway

•Two split-core current transformers (CTs) for production and

consumption metering

•Length of DIN rail for mounting

•Ferrite bead to attach to your Ethernet Cable, if used

•Quick Install Guide (this document)

C ) Check that there is enough 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 Envoy-S 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 appro-

priately rated enclosure if installing the Envoy-S indoors.

E ) If you are installing the Envoy-S in a multi-phase application, 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. Install a phase coupler on the load side of the

over-current protection device. See the Technical Brief on Phase

Coupling for your region at enphase.com/support. Consult En-

phase support for compatible devices.

F ) Decide how to connect the Envoy-S to the Internet: choose to use

Wi-Fi, an Enphase Mobile Connect modem, or Ethernet.

G ) Make sure you have the following optional items, if needed:

•Enphase Mobile Connect™ modem (order CELLMODEM-02)

•Ethernet over power line communication (PLC) bridge with Ether-

net cables [order EPLC-02 (EU), EPLC-03 (UK) or EPLC-04 (AU/NZ)]

•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. You will scan this map later using Installer Toolkit and

your mobile device.

• As you did with the microinverters (and Enphase AC Batteries, if

installed), peel the removable label from the bottom of the Envoy-S

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.

Detect Devices and Select the Grid Prole

Use one of the following methods to detect devices (Enphase Microinvert-

ers and/or Enphase AC Batteries).

Method A // Provision devices with Installer Toolkit

Use the Installer Toolkit mobile app to congure the Envoy-S with the

serial numbers of the installed devices.

A ) Select the system you are working with, or tap [+] to add a system.

B ) If the serial number for the Envoy-S you are installing is not displayed

on the System Overview screen, tap the [+] next to the word “Envoys”.

When the app displays the serial number of the Envoy-S, tap it to add

it to the system.

C ) Following the on-screen instructions to create the arrays and scan the

serial numbers from the installation map..

D ) Tap the Connect button. This provisions the scanned devices on the

Envoy-S.

E ) When prompted, conrm the number of devices that you installed and

select the grid prole.

The Device Communications LED lights solid green if all of the provisioned de-

vices are communicating or solid amber if any devices are not communicating.

Method B // Discover devices with Installer Toolkit

Use the Installer Toolkit mobile app to set the number of devices the

Envoy-S should search for on the power line.

A ) Tap Connect to an Envoy.

B ) When prompted, enter the number of devices that you installed and

select the grid prole.

C ) When prompted to start a device scan, tap OK.

The Device Communications LED ashes green while scanning. It lights

solid green when all of the devices you installed are communicating or

solid amber if any devices are not communicating.

With all methods

If the Device Communications LED remains solid amber, see Trouble-

shooting b.

Verify System Conguration

While still connected to the Envoy-S with Installer Toolkit, check the Over-

view screen for the following:

A ) Conrm that the expected number of devices are detected and com-

municating.

B ) On the Overview screen, check that the new prole is set on all the

devices. This may take up to 5 minutes for a typical system.

C ) Tap the Meters button.

D ) If there is a check next to Production Meter, the production meter

is enabled. If a gear is shown, you must enable the meter:

• Tap Production Meter. If the meter mode is Multi-Phase, select

the number of Phases Metered. This is based on how your Envoy-S

is wired. For example, if the Envoy-S is wired for three, select three

phases.

• Follow the on-screen instructions to enable the Production Meter.

E ) If you installed consumption metering CT(s), tap Consumption Meter

to enable the meter.

• If the meter mode is Multi-Phase, select the number of Phases Me-

tered. The available options will match or exceed the value selected

for the Production Meter.

• Based on where you installed the consumption CT, indicate whether

the circuit that passes through the consumption CT includes:

- Load with solar production (net) or

- Load only (total or gross), for example, in the case of a line-side

tap.

• Follow the on-screen instructions to enable the Consumption Meter.

If you change the number of Phases Metered to exceed the number

selected for the Production Meter, the system increases the number

for both meters and prompts you to conrm.

F ) Return to the Overview screen and verify the meter reading(s).

If you used Installer Toolkit to detect devices, 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 ashes green

when microinverters are upgrading. Check Installer Toolkit for production

status details. If the Power Production LED remains solid amber, see

Troubleshooting c.

NOTE: In systems where a central disconnect (or contactor)

is installed, you must congure the meters as described in

Step 6 before device discovery can complete.

INSTALLATION

Choose a location for the Envoy-S

A ) Install the Envoy-S Metered near the switchboard and consider the

length of the CT leads (4 meters) when choosing the location. If

you need to extend the leads (up to 148 meters), refer to the Enphase

Envoy-S Installation and Operation Manual at: enphase.com/support.

B ) Install the Envoy-S Metered in a protected dry space. If outdoors,

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 Envoy-S 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 75º C 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 Nm.

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 Nm.

The Envoy-S 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 Envoy-S. If you need to extend the leads (up to 148 meters), refer to the Enphase Envoy-S

Installation and Operation Manual at: enphase.com/support.

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 Nm.

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.

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.

bDevice detection issues

If the Device Communications LED lights solid amber, it may be a result of low

light levels. If there isn’t enough sunlight to power up the microinverters, they can’t

communicate with the Envoy.

If there is sufcient daylight for the microinverters to power up, the issue may be that

the Envoy-S is having difculty communicating over the power lines. To troubleshoot

this issue:

• Check the Installer Toolkit mobile 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 amber, check the Installer Toolkit mobile

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 micro-

inverter (22V). 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 Envoy, 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 amber, 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 amber, see Troubleshooting in the Enphase Mobile

Connect Installation Guide.

For any connection method, you can troubleshoot network issues with the Installer

Toolkit mobile app by tapping the Network button, then Diagnostic Tools.

If you replace the broadband router, congure the Envoy-S Wi-Fi settings for the new

Wireless Network Name (SSID) and password.
