Envoy Installation and Operation

Issue: Envoy Displays Zero Bars

The following conditions may exist.

Is there a phase imbalance?

 Ask the electrician to measure the conductors and neutral line to verify that the phases are

balanced. If the phases are not balanced, electricians must recheck the wiring.

Is the system energised? PV modules power microinverters, PV modules provide power only

during daylight hours, and microinverters communicate only when powered.

 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 PV circuit breakers must be in the “ON” position in

the electrical AC mains.

 Verify that the PV modules are connected to the microinverters.

The Envoy is plugged into a circuit on the primary AC mains, but the PV circuit breakers are on

a downstream subpanel: The primary AC mains 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 AC outlet, so that it can be close to the PV circuit breaker.

Local Area Networking Troubleshooting

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 support@enphaseenergy.com for Envoy issues, but

Enphase's Support responsibility does not extend to the premises network or LAN.

Issue: IP Address Problems

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 the internal network, this means that the Envoy was unsuccessful in

obtaining a DHCP lease from the 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 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 Envoy menu button to “Get New IP Address”, and then allow 30 to 60 seconds for

the new IP address to appear on the Envoy LCD screen.

 Two small green LEDs on the Ethernet port indicate Internet link and activity. One LED will

be solid green, and the other will blink green every few seconds. If the LEDs are not both on

or blinking, try using a new Ethernet (CAT5) cable in place of the existing cable.

 Unplug all units in the chain, applying power again in this order: 1) modem, 2) router, and 3)

Envoy. Allow a few minutes for the IP address to be reassigned.

Issue: LCD Screen Displays “-Web”

This means that the Envoy has no connection to the Enlighten website. To troubleshoot the issue:

 Check network connectivity to the router. You may also wish to contact your Internet Service

Provider or refer to your router documentation for assistance.

 Unplug all units in the chain, applying power again in this order: 1) modem, 2) router, and 3)

Envoy. Allow a few minutes for the IP address to be reassigned.

 Allow a few minutes longer. If the Envoy has recently received a valid IP address, it will likely

display “+Web” momentarily.
