Description
Recommended Action: Unplug the Envoy from the electrical outlet
and plug it in once again. Leave it plugged in and in place for at least
15 minutes.
Description: This message displays after the Envoy has tried
unsuccessfully three times to start up.
This condition does not affect your system's ability to produce power,
and when the connection is restored, the Envoy will catch up with the
transmission of any/all energy data it has stored.
If the condition persists: If the Envoy continues to display
Gateway (or Envoy) Failure or if it never moves beyond the
Initialization stage, contact your installer or refer to the
Troubleshooting Guide at http://www.enphase.com/support/.
Description: The Envoy file system integrity audit has failed.
For assistance, contact Enphase Energy customer support.
Recommended Action: In most cases no action is required. If there
is a power outage in your area and the system has stopped
production, solar production will resume when the utility restores
power to your area.
Verify that the circuit breaker(s) for the PV array are ON at the load
center. If all breaker(s) are on, the condition should clear itself.
Description: The microinverter detects no power coming from the
local Utility.
Enphase microinverters are "utility interactive" and require a
connection to the utility.
If the condition persists: If Grid Gone events persist, contact your
installer or refer to the Troubleshooting Guide at
http://www.enphase.com/support/.
Description: The microinverter is not producing power due to one or
more of these conditions: AC Frequency Out Of Range, AC Voltage
Out Of Range, or Grid Gone. Note that Grid Instability will remain for
about 5 minutes after the underlying conditions clear. No power is
produced during this time.
No action is required unless the condition persists. If it persists,
contact Enphase Energy customer support.
Recommended Action: No action is required unless the condition
persists.
Description: The average current to the grid is too high 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 high, 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/.
