IUP Link
Problem
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.

microinverter.
No action is required.

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 load center. Also, if other devices are
sharing the receptacle with the Envoy, remove those devices 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 Communication 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 and 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
24, or contact your installer, or refer to the
