Issue: LCD Screen Displays “Envoy Failure +Web or -Web”
This message displays after the Envoy has tried unsuccessfully three times to initialise.
Unplug the Envoy from the AC outlet and plug it in once again. Leave it in place for at least
15 minutes.
If it continues to display Envoy Failure or if it never moves beyond the Initialization stage,
contact Enphase Customer Support (support@enphaseenergy.com).
Issue: The Envoy has Good Signal Strength but is Too Far from the Router
In this case, you may need to use power line communication bridges or a wireless Ethernet
bridge.
Replacing an Envoy
If problems remain after following the troubleshooting steps above, contact Enphase at
support@enphaseenergy.com. If Customer Support authorises an Envoy replacement (RMA), follow the
steps below.
1. Disconnect the Ethernet cable and power cord from the old Envoy.
2. When the replacement Envoy arrives, connect it to the Ethernet cable and power cord.
3. Verify that the new Envoy powers up. The Envoy LCD may display "Upgrading... Do Not
Unplug" for up to 15 minutes. Wait for this to complete before proceeding.
4. Verify that the new Envoy indicates +Web within 15 minutes. If not, follow the network
troubleshooting steps above.
5. Verify that the new Envoy start discovering microinverters within 20 minutes of starting up. If
necessary, use the LCD menu (or the Enlighten Envoy page) to start a new device scan
during daylight hours. (See Using the Envoy LCD Menu on page 21.)
6. After all microinverters have been discovered, stop the new device scan using the LCD
menu. (See Using the Envoy LCD Menu on page 21.)
7. Assess the power line communications by running a Communication Check from the LCD
menu (or from the Enlighten Envoy page) during daylight hours. (See Using the Envoy LCD
Menu on page 21.) If fewer than three bars are shown, relocate the Envoy for better power
line communications.
8. Ship the old Envoy to Enphase using the supplied RMA shipping label.
