IQ Envoy Installation and Operation
Troubleshooting
The following sections describe possible problems and solutions.
WARNING : Risk of electric shock. Risk of fire. Do not attempt to repair the IQ Envoy; it contains no user-serviceable parts. Tampering with or opening the IQ Envoy will void the warranty. If the IQ Envoy fails, contact Enphase Customer Support for assistance
( enphase.com/en-us/support/contact ). 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 other Envoy(s) have been detected. To prevent this issue:
•
When multiple IQ Envoy units exist on a common service panel or utility transformer, commission only one system at a time at installation.
•
When multiple IQ Envoy units on a common service panel, use power line filters and separate the conduits and wires by at least 32 centimeters ( 12 inches).
If this alert persists or if the Installer Toolkit Microinverters screen or Enlighten shows more microinverters than expected, contact Enphase Customer support at enphase.com/en-us/support/contact .
Issue: Device Communications LED is Solid Amber
If the Device 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 Envoy may be 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 insufficient PV module voltage to power the microinverter. 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.
•
Alternatively, wire the Envoy to 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.
