GridProfile-
Incompatible
Recommended Action: Ask your installer to use the Envoy Interface to
select a grid profile that is compatible with the installed microinverters.
Description: This message displays when the selected grid profile is
incompatible with microinverter hardware.
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: Contact your installer or refer to “Change or
View the Grid Profile” on page 36.
Grid Gone
Grid Gone
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 AC mains. 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/downloads/.
Grid Instability
Grid Instability
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 five
minutes after the underlying conditions clear. No power is produced during
this time.
Recommended Action: No action is required unless the condition
persists. If it persists, contact Enphase Energy customer support.
Grid Offset Hi
Grid Offset Hi
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/downloads/.
Grid Offset Low
Grid Offset Low
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/downloads/.

Description: The Envoy has completed a change to the grid profile for the
microinverters. No action is required.
HardwareError
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.
