Page 5: Important Information
Follow the instructions in this manual. These instructions are key to the installation and maintenance of the Enphase Envoy® Communications Gateway (Envoy). To ensure the safe installation and operation of the Envoy, note the following safety symbols that appear throughout this document to indicate dangerous conditions and important safety instructions. -
Page 6: The Enphase Envoy Communications Gateway
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. -
Page 7: Other Elements In The Enphase System
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. -

Page 10: Install The Envoy
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. -
Page 11: Register The Envoy
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. h. Under Modules, enter total number of modules, type, etc. -
Page 12: Find A Location For The Envoy
Envoy Installation and Operation 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. -
Page 13: Method A: Ethernet Cable
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. -
Page 14: Select Language
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. -
Page 15: Check The Internet Connection
