Internet Connection Issues; Issue: Network Communications Led Is Amber Or Off - enphase IQ Envoy Installation And Operation Manual

solid amber when any microinverter that is expected to produce does not. Use Installer Toolkit to see which
microinverters are affected.
If none of the microinverters are producing power, there may be a grid or wiring issue. First, verify
•
that there is proper input voltage and frequency from the grid. Next, check the breaker and wiring
starting at the load center.
If all of the non-productive microinverters are on the same branch, check the breaker and wiring
•
starting at the junction box for the affected branch.
If only one or scattered microinverters are not producing power, first check to see that the AC
•
connectors are fully seated in the Engage Cable connectors. Next, check that each module is
meeting the required start-up voltage for the microinverter (usually 22 V). A PV module that is failing
or that is undersized may not generate enough power for AC conversion.
Microinverters will not report production if they are not communicating with the IQ Envoy. Refer to
•
"Device Detection Issues" on page 34 for troubleshooting steps.

Internet Connection Issues

To the Local Area Network (LAN), the Envoy is just another host on the network, much like a personal
computer. Enphase offers technical support at
Enphase's Support responsibility does not extend to the premises network or LAN.
The Envoy must obtain a DHCP (Dynamic Host Configuration Protocol) IP address and have a route to the
Internet. The Envoy will request this IP address from the broadband router during the power-up sequence.
Two small green LEDs on the Ethernet port indicate Internet link and activity. During the sequence, one LED
will be solid green, and the other will blink every few seconds.

Issue: Network Communications LED is Amber or Off

The IQ Envoy is configured to perform a DHCP broadcast when it first boots up, and requests an an IP
address from a DHCP source. This source can be a server/computer, but almost all consumer-grade
broadband routers also provide DHCP services. When the Network Communications LED
the IQ Envoy has a local network connection only and failed to connect to Enlighten after its scheduled
reporting time (five minutes). When the LED is off, there is no network connection.
If you are using the Enphase Mobile Connect modem and the Network Communications LED
or lights solid amber, see Troubleshooting in the Enphase Mobile Connect Installation Guide.
For any connection method, you can troubleshoot network issues using the Installer Toolkit mobile app by
tapping the Network button, then Diagnostic Tools.
Allow 10 minutes after initial installation. If the Envoy has recently received a valid IP address, the
•
LED will likely turn green momentarily.
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 help.
Check that you are using a broadband 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 Installer Toolkit to Get New IP Address, and then allow 30 to 60 seconds for the Network
•
Communications LED
When the IQ Envoy is connected to the LAN via Ethernet cable, two small LEDs on the Ethernet port
•
indicate Internet link and activity. One LED will be solid green, and the other will blink green or yellow
every few seconds. If either LED is neither on nor blinking, try using a new Ethernet (CAT5) cable in
place of the existing cable.
