The Enphase Envoy Communications Gateway
The Envoy is an integral component of the Enphase Energy 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 in-home 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
the Enphase Envoy Communications Gateway
the Enphase Enlighten™ web-based monitoring and analysis
This integrated system maximizes energy harvest, increases system reliability, and
simplifies design, installation and management. The following diagram shows the
Envoy in the system.
Other Elements in the Enphase System
The Enphase Microinverter is a fully integrated device that converts the DC output of
the PV module into electric utility compliant AC power. In addition to performing the DC to
AC conversion, it maximizes the PV modules' energy production by using a sophisticated
Maximum Power Point Tracking (MPPT) algorithm. This integrated system maximizes
energy harvest, increases system reliability, and simplifies design, installation and
management.

The Enphase Enlighten web-based monitoring and analysis system analyzes the
per-module data collected by each communicating microinverter. Enlighten
automatically detects any shortfall in energy production, identifies possible causes,
and suggests solutions. Enlighten constantly monitors every microinverter connected
to the Envoy.
How the Envoy Communications Gateway Works
Installation and operation of the Envoy requires no special computer or networking
knowledge, nor any specialized equipment. The Envoy simply connects to the on-site
router for communications with the Enphase Enlighten monitoring and analysis
website. The Envoy is required for all Enphase Microinverter installations, and
communicates with the individual microinverters using the existing power lines in
the residence or business.
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. The Envoy is
used to configure the microinverters with the appropriate grid profile. The
microinverters must be configured with the appropriate grid profile as part of the
commissioning process or they will not produce power.
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 the
Enphase Enlighten monitoring and analysis website. The Envoy also reports any
error conditions that affect itself or the microinverters. You can view both energy
data and error conditions in the Enphase Enlighten web-based monitoring and
analysis system.
The Envoy incorporates power line and Internet communications functions. As
shown in the following 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 your broadband router.

3. Find a Location for the Envoy
Enphase recommends that the Envoy be placed as close to the load center as
possible. This ensures that the Envoy receives the strongest possible signal from
each microinverter.
a. Locate an electrical outlet close to the site’s load center. Place the Envoy
so that its AC cord can reach this outlet.
b. The Envoy can be placed on a table or it can be wall mounted. For wall
mounting instructions, see Wall Mounting on page 11.
4. Connect to AC Power
a. Plug the AC power cord into the AC input on the Envoy.
b. Plug the other end of the power cord into an ordinary power outlet (not a
power strip). For best results, the outlet should be near the load center.
WARNING! Do not plug the Envoy into a power strip, surge protector, or
uninterruptable power supply (UPS). The surge suppression or filtering from
a power strip or other protective device can substantially diminish
communication performance. If possible, do not plug a power strip power
cord 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 close to the Envoy.
5. Connect Ethernet Cabling
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.
The Envoy needs to obtain a DHCP (Dynamic Host Configuration Protocol) IP address
and have a path to the Internet. The Envoy will request a dynamically assigned
(DHCP) IP address from the broadband router during the power-up sequence.
Two small green LEDs on the Ethernet port indicate link and activity. One LED will be
solid green, and the other will blink green every few seconds.
6. Connect Power Line Communication Bridges (Optional)
If the Envoy needs to be located away from the router, at a distance where an
Ethernet cable is not practical, use the power line communication bridges provided
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.
Install the power line communication bridges:
a. Plug one of the bridges into the same wall socket that the Envoy’s power-
cord is plugged in to.
b. Connect one end of the Ethernet cable into the Ethernet port on the Envoy.
c. Connect the other end of that Ethernet cable into the bridge.

into a wall-socket
near your broadband
router.
e. Connect one end of a
second Ethernet
cable into that
second bridge.
f. Connect the other
end of that Ethernet
cable into the
broadband router.
g. Reapply power to the
Envoy to force it to
refresh its IP
address.
7. Select Language
After the Envoy starts up it will request that you set the Language.
a. The Envoy LCD panel will scroll through the available language settings.
When you see the setting you need, press the Menu button and hold for two
seconds.
8. Check the Envoy’s Progress

9. Wall Mount the Envoy (Optional)
NOTE: Before mounting the Envoy, it is best to perform a Communication
Check as described on page 20 to optimize the location of your Envoy.
After you have positioned your Envoy for optimal communications and it is has
begun to detect devices, you may want to mount the Envoy on a wall. To do this:
a. Select a cool, dry, indoor location for the Envoy.
b. Use two drywall screws or wall anchors (not included in kit) to affix the Envoy
to the wall, mounted at the dimensions shown. You will need two #8 (4,166
mm or 0,164 inch diameter); maximum screw head diameter is 8.9mm (0,35
inches). A #8 screw is recommended.
c. Slide the Envoy onto the mounting screws, aligning the Envoy screw holes
with the screws installed in step b.

10. Configure the Grid Profile
The following steps describe how to configure the grid profile. After all of the
microinverters at the site are detected, you can apply the grid profile.
If you need to change the grid profile subsequent to this procedure, follow the steps
in Change the Grid Profile on page 32.
Each Grid Profile contains a set of trip points. Trip points are input voltage or
frequency values that trigger the microinverters to shut down. These trip points vary
from region to region. You will need to set the grid profile.
NOTE: Enphase Microinverters will not begin exporting power until the Envoy
Communications Gateway is installed and has detected all of the microinverters
at the site. In addition, the grid profile must be configured and the Envoy must
have propagated these settings to the microinverters.
a. Open the Internet browser application on a computer that is connected to the
same local network as the Envoy.
b. In the browser address window, enter the IP address displayed in the LCD
screen of the Envoy.
Once the browser has successfully connected with the Envoy, the System Overview
screen is displayed in the browser window.
c. From the Language menu, select your preferred language.

Envoy Operation
Initial Screen Displays
It takes less than five minutes for the Envoy to be ready to work after applying
power. This five-minute period is known as a boot sequence. 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. This
information is displayed on the “home screen”. The boot sequence is shown:
The Envoy normally displays "-Web" for 2 to 3 minutes after the first start up. It
then sends the first report to Enlighten. If Enlighten responds, the Envoy displays
+Web. Power production will show as 0W and 0kWh until the microinverters are
discovered, the grid profile is applied, and power production begins.
