Microinverter Detection Issues

Troubleshoot power line communication issues as follows.

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 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:
