Description
Description: The Envoy has detected and is now associated to a new
microinverter.
No action is required.
Recommended Action: Ignore occasional instances of this event.
Communication usually recovers on the next reporting cycle.
If communications do not recover immediately, ensure that the Envoy is
plugged in very near the AC mains. Also, if other devices are sharing the
outlet with the Envoy, remove those devices from the outlet to improve
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, 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 "Communication 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/support.
Description: The attempt to change the grid profile for the microinverters
has failed after five tries. The Envoy will continue to attempt to change the
grid profile.
Recommended Action: No action is required.
Description: A failed attempt to change the grid profile for the
microinverters has cleared. The grid profile was successfully applied.
xx = number of attempts
Recommended Action: No action is required.
Description: The microinverter is off for the night.
Recommended Action: No action is required.
Recommended Action: Ask the installer to use the Envoy Gateway
interface to select a grid profile for this system. For more information, see
"Change or View the Grid Profile" on page 40
Description: The Envoy has not been set up with a grid profile for the
microinverters.
Description: The microinverter is too hot and is not producing power. This
very rare condition usually clears without intervention.
Recommended Action: No action is required unless the condition persists.
If it persists, contact Enphase Energy customer support.
Description: The microinverter is not producing power by user command.
This uncommon condition will occur only during isolated troubleshooting
procedures by Enphase personnel.
Recommended Action: No action is required.
