Envoy Installation and Operation
2014 Enphase Energy Inc. 141-00011 Rev 05
To use the Envoy Menu button to initiate a communications check:
1. Press and hold the Menu button on the right side of the Envoy to bring up the Envoy menu on the
LCD screen.
2. When the LCD screen displays “Enable Communication Check”, release the Menu button.
The LCD screen then reads:
The Envoy begins a 20-minute communications check to assess the signal strength between the
Envoy and the microinverters detected at the site. Until the Envoy begins detecting
microinverters, the display reads:
NOTE: The communications check displays communication levels for devices already in the
Envoy database; it does not scan for new devices.
When the Envoy begins detecting microinverters, the display shows power line communication
Level and Device count:
To the right of the word “Level”, you’ll see brackets enclosing zero to five bars. The example
above shows three bars.
NOTE: Until microinverters are detected, the Level indicator shows no bars.
Signal strength is acceptable if three to five bars are displayed and all devices are accounted for.
One to two bars may not be sufficient for consistent communication.
3. If, after 15 minutes, fewer than three bars are displayed, refer to “Power Line Communication
Troubleshooting” on page 29.
The “Devices” counter displays the number of microinverters detected and will increase until all
microinverters are detected. Ultimately, the number of microinverters detected should match the
number of installed microinverters.
4. After 20 minutes, the communications check stops. To stop the communications check before it
times out, press and hold the menu button to activate the Envoy menu. When “Disable
Communication Check” is displayed, release the menu button.
