Where message is displayed:
Description

Module added
Description: The Envoy has detected and is now associated to a new
microinverter.
No action is required.
Microinverter
failed to report
Failed to report
Recommended Action: You can ignore occasional instances of this error.
Communications will likely recover on the next reporting cycle.
If communications do not recover immediately, make sure that the Envoy
is plugged in very near to the AC mains. Also, if other devices are sharing
the outlet with the Envoy, remove those devices from the outlet to improve
communication signal strength.
If the Enphase Envoy was recently relocated or if new devices or
appliances were added to the circuit, it is possible that the new situation is
not suitable for power line communication. The Envoy may need to be
relocated to improve signal strength and reduce interfering noise on the
power lines.
To determine the quality of the Envoy’s location for communication, please
run a Communications check by holding down the Envoy’s menu button
until the LCD display reads “Enable Communication Check” and then
release the menu button. The Envoy will then broadcast a signal to the
microinverters. Within 5 minutes, a “Comm Level” indication of 0 to 5 bars
will display on the Envoy LCD display. The Envoy requires a minimum of 3
bars to communicate effectively with the microinverters.
Description: The Envoy reporting this condition is unable to communicate
with the microinverters over the power lines.
If the condition persists: See “Power Line Communication
Troubleshooting” on page 29, or contact your installer, or refer to the
Troubleshooting Guide at http://www.enphase.com/downloads/.
