Description
GwFailure (Gateway
Failure)
Description: This condition occurs after the Envoy has tried unsuccessfully three
times to start up.
This condition does not affect your system’s ability to produce power. When the
connection is restored, the Envoy will catch up with the transmission of any/all
energy data it has stored.
Recommended Action: Unplug the Envoy from the AC outlet and plug it in once
again. Leave it plugged in and in place for at least 15 minutes.
If the condition persists: If the condition persists, contact your installer or refer to
the Troubleshooting Guide at enphase.com/support.
HardwareError
Recommended Action: Contact your installer to arrange for the installation of a
replacement microinverter.
Description: A hardware failure has occurred that prevents power conversion.
IupLinkProblem
Recommended Action: No action is required unless the condition persists.
Description: The IUP (Inter Microprocessor) is the internal communications link
between the two sides of a D380 Microinverter. The message indicates that the
Envoy detects a communications problem with the indicated D380(s).
If the condition persists: Contact Enphase Customer Support at
[e-mail] for a software upgrade. If the D380 does not respond
to the upgrade, it will need to be replaced.
ModuleAdd
Description: The Envoy has detected and is now associated to a new
microinverter.
No action is required.
Microinverter failed to
report
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 load center. 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.
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 34, or contact your installer, or refer to the Troubleshooting Guide at
enphase.com/support.

attempts, retrying
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.
Microinverter grid
configuration failure cleared
after xx attempts
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.
