Envoy and Communications Issues
The following sections describe possible problems and
solutions. Areas include:
Envoy Issues
Networking and Internet Issues
Power Line Communication Issues between
the Envoy & Microinverters
WARNING: Do not attempt to repair the
Enphase Envoy; it contains no user-
serviceable parts. Tampering with or
opening the Envoy will void the warranty. If
the Envoy fails, contact Enphase customer
service to obtain an RMA (return
merchandise authorization) number and
start the replacement process.
Envoy Issues
A physical Ethernet connection is not
practical at the site
The location for the Envoy yields a good signal-
strength between the Envoy and the Microinverters
(over the power lines), but it is remote from the
router. An Ethernet cable from the broadband router
to this spot is not practical.
Try these solutions:
Use an Enphase Wireless Adapter (order
WF-01) as shown.
Use Enphase power line communication
bridges (order ELPC-01) with the Envoy as
shown.
Or, you can use a third-party wireless
Ethernet bridge (available at computer
stores).
