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
([e-mail]). Warranty void if cover removed. Refer servicing to qualified
personnel.
Microinverter Detection Issues
Troubleshoot power line communication issues as follows.
Issue: Microinverter Communications LED is Solid Amber
If the Microinverter Communications LED lights solid amber, it may be a result of low light levels. If there
is 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 microinverters 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 Microinverters than Expected
The Microinverters detected count 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 microinverters
are not reporting in to the Envoy or having any error conditions.
 If installing the Envoy-S Standard, make sure that the Envoy is plugged directly into the wall and
not into a power strip or surge protector. Unplug any other device that is sharing the outlet with
the Envoy. Or, as an alternative, plug the Envoy into a circuit that supports fewer electronic
appliances. Appliances sharing a power receptacle with the Envoy may interfere with power line
communication.
 Relocate your Envoy as close to the AC mains as possible. This ensures that the Envoy receives
the strongest possible signal from each microinverter.
 If this problem occurs when light levels are low, try again during daylight hours.
Issue: No Microinverters are Reporting
Check for the following conditions.
Has a device scan been run while the array was active? A device scan may have been run while
the array was not connected to the grid or when the array was not powered by sunlight.
 Run another scan during daylight hours.
