Local Area Networking Troubleshooting - Enphase Energy Envoy Manuel D'installation

• Run another scan during daylight hours.
•
Check that the circuit breaker(s) for the PV array are in the "ON" position.
For the Envoy to communicate with the microinverters, the circuit breakers
must be in the "ON" position in the load-center.
• Verify that the PV modules are connected to the microinverters.
3. Envoy plugged into a circuit on the primary load center, but the PV
circuit breakers are on a downstream subpanel: The primary load center is
full and doesn't have additional capacity to add circuit breakers.
• Add a subpanel with a small subset of circuit breakers. In this case, it is best
to add an additional 5-Amp circuit breaker and then run an outlet off that
subpanel. Plug the Envoy into that outlet, so that it can be close to the PV
circuit breaker.

Local Area Networking Troubleshooting

PROBLEM: IP address issues. If the IP address displayed on the Envoy's LCD
screen is 169.254.120.1, or if the IP address does not match the DHCP subnet on
your internal network, this means that the Envoy was unsuccessful in obtaining a
DHCP lease from your router.
• Check network connectivity to the router or other DHCP server. You may also
wish to contact your Internet Service Provider or refer to your router
documentation for assistance.
• Check that you are using a network router and not a switch or a hub. Many
hubs and switches cannot provide a DHCP lease and may not allow the Envoy
to connect to the web.
• Use the Envoy menu button to "Get New IP Address". See page 19 for more
information.
• Unplug all units in the chain, applying power again in this order: Modem,
Router, and Envoy. Allow a few minutes for the IP address to be reassigned.
PROBLEM: LCD screen displays "-Web". This means that the Envoy has no
connection to the Enlighten website.
•
Check network connectivity to the router. You may also wish to contact your
Internet Service Provider or refer to your router documentation for
assistance.
• Allow a few minutes longer. If the Envoy has recently received a valid IP
address, it will likely display +Web momentarily.
PROBLEM: LCD screen displays "Envoy Failure +Web or -Web". This message
displays after the Envoy has tried unsuccessfully three times to initialize.
• Unplug the Envoy from the electrical 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, call Enphase Customer Support.
PROBLEM: The Envoy is in a location that yields a good signal-strength, but
using an Ethernet cable here is not practical:
• In this case, you may need to use Power line Ethernet bridges or a wireless
Ethernet bridge.
