LCD is completely blank

1. Try another outlet (just in case).
2. If this fails, the Envoy unit must be replaced. There are no field replaceable parts for the Envoy.
Contact Enphase Customer Support support@enphaseenergy.com.

LCD displays "Reset Clock"

If the Envoy has a current Internet connection, let it use this connection to retrieve an upgrade from
Enlighten. This may take up to 20 minutes, depending upon the speed of the connection. You may need
to contact Enphase Customer Support to initiate the upgrade.

LCD displays "Envoy Failure"

This message displays after the Envoy has tried unsuccessfully three times to initialize. This may happen
when the Envoy has been moved, and its initialization process interrupted.
1. Unplug the Envoy from the electrical outlet, and then plug it in again. Leave the Envoy in place for
at least 15 minutes.
2. If it continues to display Envoy Failure or if it never moves beyond the Initialization stage, contact
Enphase Customer Support.

LCD displays "Scanning Inhibited"

This message displays after an installer has used the Installer's Toolkit to provision the Envoy. Leave the
Envoy in this condition for normal operation. If you need to re-enable scanning, contact Enphase
Customer Support (support@enphaseenergy.com).
