Troubleshooting

The following sections describe possible problems and solutions.
WARNING: Risk of electric shock. Risk of fire. Do not attempt to repair the Envoy-S; it
contains no user-serviceable parts. Tampering with or opening the Envoy-S will void the
warranty. If the Envoy-S fails, contact Enphase Customer Support for assistance
(enphase.com/global/support-request). Warranty void if cover removed. Refer servicing
to qualified personnel.

Device Detection Issues

Troubleshoot power line communication issues as follows.

Issue: Installer Toolkit Shows "Cross Domain Traffic Reported"

This means that communications from another Envoy(s) have been detected. To prevent this issue:
 When multiple Envoy-S units exist on a common switchboard or transformer, commission
only one Envoy-S system at a time during installation.
When multiple Envoy-S units on a common switchboard, use power line filters and separate

the conduits and wires by at least 32 cm (12 inches).
If this alert persists or if the Installer Toolkit Devices screen (or Enlighten) shows more devices than
expected, contact Enphase Customer support at enphase.com/global/support-request.

Issue: Device Communications LED is Solid Amber

If the Device Communications LED
not enough sunlight to power up the microinverters, they cannot communicate with the Envoy. If there is
sufficient daylight for the microinverters to power up, the issue may be that the Envoy is having difficulty
communicating over the power lines. To troubleshoot this issue:
Check the Installer Toolkit mobile app to see which devices are not communicating.

Check that the circuit breaker(s) for the PV array are in the "ON" position.

Verify that the PV modules are connected to the microinverters.

 Verify the PV module DC voltage is within the allowable range for the microinverter.

Issue: Installer Toolkit Detects Fewer Devices than Expected

The Microinverters detected count shown in Installer Toolkit is an indication of the number of online
microinverters producing power, reporting in to the Envoy, and not having any error conditions. If this
number is lower than expected, it may indicate that the Envoy is not done scanning/discovering the entire
array. Alternatively, it may indicate that the Envoy is having difficulty communicating over the power
lines. It could also be a result of low light levels or that the PV module voltage is too low for the
microinverter to power up. To troubleshoot the issue:
Check Enlighten or use the Installer Toolkit to connect to the Envoy to see if any devices are

not reporting in to the Envoy or having any error conditions.
Check the circuit that the Envoy-S is using. Appliances sharing a circuit with the Envoy may

interfere with power line communication.
