Step 2: Connect The Envoy Communications Gateway - enphase M250 Installation And Operation Manual

Step 2: Connect the Envoy Communications Gateway

The Envoy operates between the Enphase Microinverters and the Enphase Enlighten® web-based
monitoring and analysis software. 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 Envoy is capable of monitoring up to 600 Enphase Microinverters.
a. Connect the Envoy to power and Internet according to the Envoy Quick Install Guide.
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, 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.
b. During start up, the Envoy LCD panel scrolls through the available language settings. When
you see the setting you prefer, press the Menu button and hold for two seconds.
c. Wait for the "+Web" indication on the Envoy's LCD screen.
d. Leave the Envoy running while you install the microinverters so that any required Envoy
software upgrade completes.
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 20
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."
