The Enphase Envoy Communications Gateway
The Envoy® Communications 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 Envoy functions as a gateway and monitors the microinverters
that are connected to the PV modules. The Envoy collects energy and performance data from the
microinverters over on-site AC power lines. It then forwards that data to Enlighten, via the Internet, for
statistical reporting.
The three key elements of an Enphase system are the:
Enphase Microinverter
Enphase Envoy Communications Gateway
Enphase Enlighten web-based monitoring and analysis software
This integrated system maximises energy harvest, increases system reliability, and simplifies design,
installation and management. The following diagram shows the Envoy in the system.

Envoy Installation and Operation
7 2014 Enphase Energy Inc. 141-00014 Rev 04
Other Elements in the Enphase System
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 Enphase Enlighten web-based monitoring and analysis software analyzes 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 Envoy and is essential for monitoring and troubleshooting.
How the Envoy Communications Gateway Works
Installation and operation of the Envoy require no specialised equipment or unique computer or
networking expertise. To the Local Area Network (LAN), the Envoy is just another host on the network,
much like a personal computer. The Envoy simply connects to the on-site router for communications with
the Enphase Enlighten monitoring and analysis website. The Envoy communicates with the individual
microinverters using the existing power lines in the residence or business.
IMPORTANT! The Envoy is required for each installation. It provides monitoring and
allows you to configure the Grid Profile on the microinverters. You must configure the
Grid Profile before the microinverters can export power.
After the Envoy is installed and completes its initial scan, it maintains an internal database of all known
Enphase Microinverters at the site it manages. At regular intervals, the Envoy polls each microinverter for
its energy data. Using the site’s broadband router, the Envoy then forwards that information to Enlighten.
The Envoy also reports any error conditions that affect it or the microinverters. You can view both energy
data and error conditions in Enlighten.
The Envoy incorporates power line and Internet communications functions. As shown in the diagram, one
"side" of the Envoy communicates with the microinverters through power lines at the site. The other
"side" of the Envoy communicates with the Internet using a standard Ethernet/network cable plugged into
the broadband router.

Installation Planning and Preparation
Review the following preinstallation checks before you install the Envoy.
System Sizing
The Envoy is capable of monitoring up to 600 Enphase Microinverters.
Preinstallation Checks
1. Before installing the Envoy, make sure that the site meets the following minimum requirements:
Standard AC outlet is available near the AC mains. Do not use a power strip.
Laptop or other computer is available for set up
2. To use the Enlighten web-based monitoring and analysis software, additionalrequirements are:
Always-on broadband Internet connection
Broadband router with spare Ethernet port or a wireless router if using the optional Enphase
wireless adapter.
Up-to-date web browser to view Enlighten. Supported browsers are Internet Explorer 8 or
higher, Firefox 11 or higher, Chrome 5 or higher, and Safari 5 or higher. Enlighten requires
Adobe Flash Player 10 or higher. For Internet Explorer 8 users, install the Google Chrome
Frame plug-in. Enlighten is compatible with Internet-enabled mobile devices running iOS 5 or
higher and Android 4 or higher.
3. If you are installing the Envoy (ENV-230) in a three-phase application, the power line
communication signal must be “coupled” between the three phases to allow the Envoy to
communicate with all of the microinverters in the system. Install a phase coupler (Enphase
number LPC-01), or wire a capacitor into the system. With either solution, install the device on
the load side of the over-current protection device. See the Enphase Technical Brief on Phase
Coupling for your region at http://www.enphase.com/support.
4. Check the Envoy shipping box for the following items:
Envoy Communications Gateway
Ethernet cable
AC power cord
Envoy Communications Gateway Quick Install Guide
5. If you plan to wall-mount the Envoy, you need two #8 (4.166 mm diameter) screws and a
screwdriver.

Installation Sequence

Envoy Installation and Operation
10 2014 Enphase Energy Inc. 141-00014 Rev 04
Install the Envoy
To install the Envoy, perform the following steps.
BEST PRACTICE: When powered up and connected for the first time, the Envoy may
retrieve an automatic upgrade from Enphase. Because this upgrade may take up to 15
minutes, connect the Envoy first at the site (connect to both AC power and the broadband
router) so that it performs the upgrade well before the solar module installation is complete.
WARNING! Do not remove power from the Envoy if the LCD displays:
“Upgrading. . . Do Not Unplug.”
1. Find the Envoy Serial Number
The serial number label is on the back of the Envoy, near the left mounting bracket. You can build the
system map manually, by peeling the serial number label from the Envoy and placing the label on the
installation map, or you can use the ArrayGun feature from the Enphase Installer Toolkit to easily build
and configure a system. Refer to http://enphase.com/products/arraygun/ for more information.
To manually build the installation map:
a. Remove the Envoy’s removable serial number label.
b. Attach the serial number label to the microinverter installation map, or make note of it for
registration in the next step.
If needed, you can find an installation map at the back of the Enphase Microinverter manual.

3. Find a Location for the Envoy
Place the Envoy as close to the AC mains as possible. This ensures that the Envoy receives the
strongest possible communications signal from each microinverter. Place the Envoy indoors or in an
environmentally protected location. For wall mounting instructions, see “Wall Mounting”on page 16.
NOTE: If you are installing the Envoy (ENV-230) in a three-phase application, the power line
communication signal must be “coupled” between the three phases to allow the Envoy to
communicate with all of the microinverters in the system. Install a phase coupler (Enphase
number LPC-01), or wire a capacitor into the system With either solution, install the device
on the load side of the over-current protection device. See the Enphase Technical Brief on
Phase Coupling for your region at http://www.enphase.com/support.
a. Locate an indoor AC outlet close to the AC mains.
b. Place the Envoy so that its AC cord can reach this outlet.
c. Plug the AC power cord into the AC input on the Envoy.
d. Plug the other end of the power cord into a dedicated AC outlet (not a power strip).
WARNING! When an Envoy is plugged in and powered up for the first time, it is important to
allow the database initialization process to complete in its entirety, without unplugging or
removing power. This does not apply during subsequent power-downs, even if power is
removed during the boot process.
As an alternative if signal strength is poor, power the Envoy from the solar production circuit (where local
electrical code allows for monitoring equipment on the same circuit). This provides the best possible
power line communications. Remember that you must locate the Envoy indoors (a garage, attic,
basement, or other cool, dry location) or in an outdoor weatherproof enclosure. Remember also to allow
for Ethernet access.
WARNING! Do not plug the Envoy into a power strip, surge protector, or uninterruptable
power supply (UPS). The surge suppression or filtering within these devices impede power
line communication performance. Also, if possible, do not plug a power strip into the same
outlet that the Envoy is using. The surge suppression or filtering components of a power strip
may still interfere with communications if they are near the Envoy.
4. Connect to the Internet
The Envoy requires a connection to the Internet, usually through an existing broadband router or other
access point at the installation site. To accomplish this connection, many customers use the included
CAT5 Ethernet cable. However, if using this cable is not possible, Enphase offers two other solutions.
You can purchase either of these solutions separately:
Power line communications bridge pair: Order EPLC-02 (EU), EPLC-03 (UK) or EPLC-04 (AU).
Wireless adapter (also known as a “Wi-Fi USB stick”). Order WF-01.
Connect to a broadband router using one of these three methods, described in the following sections:
Ethernet Cable
Enphase Power Line Communication Bridges
Enphase Wireless Adapter (Wi-Fi)
When using the Ethernet cable, two small LEDs on the Ethernet port indicate Internet link and activity.
One LED will be solid green, and the other will blink green or yellow every few seconds.

Envoy Installation and Operation
13 2014 Enphase Energy Inc. 141-00014 Rev 04
Method A: Ethernet Cable
a. Plug the Ethernet cable into the Ethernet port on the
Envoy.
b. Plug the other end of the cable into a spare port on the
broadband router.
WARNING! Do not remove power from the Envoy if
the LCD displays:
“Upgrading. . . Do Not Unplug.”
Method B: Power Line Communication Bridges
Order EPLC-02 (EU), EPLC-03 (UK) or EPLC-04 (AU) separately.
If you need to locate the Envoy away from the router, at a distance where an Ethernet cable is not
practical, use power line communication bridges with the Envoy or purchase a wireless Ethernet bridge.
Bridges allow the Envoy to communicate with the broadband router without the need for additional
Ethernet cabling. To install the power line communication bridges:
WARNING! Do not remove power from the
Envoy if the LCD displays:
“Upgrading. . . Do Not Unplug.”
a. Plug one of the bridges into the same AC outlet that
the Envoy is using.
b. Connect one end of the Ethernet cable to the
Ethernet port on the Envoy.
c. Connect the other end of that Ethernet cable to the
bridge.
d. Plug the other bridge to an AC outlet near the
broadband router.
e. Connect one end of a second Ethernet cable to the
second bridge.
f. Connect the other end of the Ethernet cable into the broadband router.
g. If the broadband router is operational, press and hold the Envoy menu button. Release the
button when the LCD displays Get New IP Address. Wait for 5 minutes. If this fails, unplug the
Envoy, wait for 15 seconds, and plug it back in. Wait 5 minutes for connection.
Method C: Enphase Wireless Adapter (Wi-Fi)
Order WF-01 separately.
To use the Enphase wireless adapter, you need a wireless router. To install the wireless adapter, do the
following:
NOTE: If using a wireless adapter, you must use the Enphase-provided wireless adapter,
and the router or access point must support wireless connections (Wi-Fi). Other wireless
adapters may not operate correctly and
are not supported by Enphase.
a. On the Envoy, verify that no Ethernet cable
is plugged into the Envoy RJ45 port.
b. Verify that the wireless router you are
connecting to supports Wi-Fi WPS. On the
router, look for a button labelled “WPS”. If

c. Verify that the start-up message on the LCD screen reads "R3.8" or later.
If it does not, upgrade the Envoy by connecting the Envoy Ethernet port to the broadband
router with the Ethernet cable that came with the Envoy.
WARNING! Do not remove power from the Envoy if the LCD displays:
“Upgrading. . . Do Not Unplug.”
After the upgrade completes, unplug the Ethernet cable from the Envoy.
d. Once you have verified that the Envoy is running release R3.8 (or later), plug the wireless
adapter into the left USB port (looking at Envoy from the front), and wait for 10 seconds.
e. Press and hold the WPS button on the wireless router (or access point) for two seconds. On
many routers, the WPS button flashes at this point.
f. Within two minutes, return to the Envoy. Press and hold the Envoy menu button until the Envoy
Menu appears. Release the Envoy menu button when Enable Wi-Fi WPS appears on the LCD
screen.
g. Within two minutes an updated IP address appears on the Envoy LCD screen. This IP address
begins with a “W” to indicate that a wireless connection is established.
h. If the updated IP address does not appear, retry the previous steps as the connection window
may have timed out.
i. Within a minute, the Envoy LCD screen displays +Web, indicating a successful connection to
Enphase.
NOTE: The operating temperature range for the Enphase-provided wireless adapter is 0˚C to
40˚C (32˚F to104˚F).
NOTE: If the wireless router does not support WPS or you aren't using WPS for Wi-Fi setup,
see “Network Basics and Troubleshooting” on page 30.

6. Check the Internet Connection
a. Look for the “+Web” indication.
b. If it still shows “-Web” five minutes after connecting to the broadband router, see “Network Basics
and Troubleshooting” on page 30.
NOTE: Power production shows as 0W
and 0kWh until the microinverters are
discovered, the Envoy has reported to
Enlighten, and monitoring begins. Power
production also shows 0W and 0kWh for about a minute whenever the Envoy powers up.
7. Install the Modules and Microinverters
a. Install the PV modules and the microinverters as directed by the installation manuals.
b. Use the ArrayGun to scan the microinverters. For more information, go to http://enphase.com.
c. As an alternative, you can manually build the map: peel the removable serial number label from
each microinverter and affix it to the respective location on the map.
8. Check the Envoy’s Progress
a. Check the device count (shown as “2” in the illustration). An automatic device scan will to detect
microinverters when the DC and AC connections are completed and the AC circuit is energised.
If the device scan isn't running, start a new one:
Press and hold the Envoy menu button
(on the right side of the Envoy).
Release the button when the LCD
window displays Enable Device Scan.
b. Check the power line communications. The number of “Level” bars on the Envoy LCD
Level/Devices screen should be three or more. (The illustration shows three bars.) If there are
fewer than three bars, see “Power Line Communication Troubleshooting” on page 29. If the
communication check isn't running, start a new one:
Press and hold the Envoy menu button (on the right side of the Envoy).
Release the button when the LCD window displays Enable Communication Check.
NOTE: The Envoy may display “Priority Scan is Active” on the LCD screen during the device
scan.
c. Check that the Envoy LCD shows a complete device count after about 20 minutes. If it does not,
see “Power Line Communication Troubleshooting” on page 29.
d. Check that all microinverters are discovered. As soon as all microinverters at the site have been
discovered, use the Envoy Device Scan Control menu to stop the device scan:
Press and hold the Envoy menu button (on the right side of the Envoy).
Release the button when the LCD window displays Disable Device Scan.
NOTE: The number of devices shown in the Device Scan screen may not match the
number of devices shown on the Home screen until the device scan is complete.
NOTE: For sites with neighbouring Enphase systems, do not allow a device scan to run
overnight because it may discover neighbouring microinverters when they first power-up in
the morning. Always stop the device scan in the afternoon, before leaving the site.
e. Refer to “LCD Screen Display”on page 19 for more information.

Envoy Operation
First Scan for Microinverters
A newly installed Envoy automatically performs an initial scan to discover all of the microinverters that
are installed and powered up at the site. This initial scan continues to search for new microinverters for
eight hours from initial start up of the Envoy. This one-time scan is not repeated automatically. During the
scan, you will notice some values increasing on the Envoy display.
NOTE: If the eight-hour scan expires before installation of microinverters is complete, you
must initiate a new scan. To start a new device scan, see page 22 of this manual.
NOTE: If the Envoy was not factory built with software release 3.2, the initial scan will run for
seven days. With release 3.2, the initial scan time was reduced from seven days to eight
hours. If the Envoy upgrades to release 3.2 after an initial scan has begun, the initial scan
duration remains at seven days.
WARNING: Stop the scan once all of the devices are detected (see page 15). For sites with
neighbouring Enphase systems, do not allow the device scan to run overnight because it
may discover neighbouring microinverters when they first power-up in the morning.
The Envoy identifies each device by its unique serial number. If a microinverter is added or replaced at
the site, you must initiate a new scan so that the Envoy can discover the new microinverter. To start a
new device scan, see page 22 of this manual.
After the Envoy has detected at least one new device, it automatically enters Priority Scan mode. The
LCD screen displays the following, where “nnnn” represents the number of microinverters (devices)
detected.
When the Envoy does not detect a new device during a polling interval (usually five minutes), it exits
Priority Scan mode. If, subsequently, the Envoy detects another new device, it returns to Priority Scan
mode. It remains in this mode until it again completes an interval where no new devices are detected.
Priority Scan is
Active. Devs: nnnn

LCD Screen Display at Initial Start Up
When the Envoy starts up for the first time, it goes
through the initial boot sequence. During this initial
boot sequence, the Envoy LCD screen displays start-
up progress as shown:
Initial Communications Check
The last two screens in the initial sequence alternate
until the Communications Check ends, after 20
minutes. The Envoy normally displays
"-Web" for two to three minutes after the first start up.
It then sends the first report to Enlighten. When
Enlighten responds, the Envoy displays “+Web”.
Subsequent Start Up
After a power outage or Envoy shut down, the Envoy
is ready to work just five minutes after reapplying
power. You will know the Envoy has completed
booting and has started normal operation when it
displays both an IP address and the “+Web” status
indication in the LCD screen. The normal, post-
installation boot sequence is similar to the initial start
up, although the “Initializing Data” screen is not
repeated.

Envoy Installation and Operation

Normal Operation
Once the Envoy completes a scan, normal operation begins or resumes. At this point, the indicators in
the LCD screen show current values for your system. This is the home screen:
It may be a few minutes before energy data appears or increases on the home screen after starting up
the Envoy or initiating a scan. Information shown during normal operation includes:
Local IP address, for example: 192.168.2.140 (your actual local IP address will be different). The
Envoy attempts to get a dynamically assigned DHCP (Dynamic Host Configuration Protocol) IP
address during power-up sequence. The Envoy uses the DHCP IP address as a route to the
Internet. If 169.254.120.1 is shown, the Envoy has not yet acquired a dynamic IP. Refer to
“Troubleshooting”on page 29, if this address continues to display.
Web connection indication: +Web. The web status indicates whether the Envoy is connected to
Enlighten. The status -Web indicates that the Envoy is not connected to Enlighten.
Indication of the present power-production, in watts: (n)W (where n is a number)
Indication of the life time kilowatt hours reported to this Envoy: (n)kWh (where n is a number)
Indication of the number of online microinverters producing power, reporting in to the Envoy, and
not having any error conditions: (n) (where n is a number). At night, the number of microinverters
displayed is zero.
After the Envoy establishes an IP address and the web connection, the Envoy periodically contacts an
NTP (Network Time Protocol) server to maintain an accurate local time.
