Description
Recommended Action: No action is required unless the condition persists.
Description: The average current to the grid is too low for the configured grid
profile.
When the microinverter is operating normally, no DC current is injected into the
grid. If the DC current is too low (negative), this may indicate an issue with the
microinverter.
If the condition persists: Contact your installer or refer to the Troubleshooting
Guide at http://www.enphase.com/support.
Description: The Envoy has completed a change to the grid profile for the
microinverters. No action is required.
Recommended Action: Contact your installer to arrange for the installation of a
replacement microinverter.
Description: A hardware failure has occurred that prevents power conversion.
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

to the upgrade, it will need to be replaced.
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 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 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.
