Description
Recommended Action: To clear this error using the Envoy interface, follow the
directions on page Error! Bookmark not defined.. After being reset, the condition
will clear unless the conditions causing the event remain or if the failure is
permanent.
Description: A microinverter has detected ground fault current greater than one
amp on the DC side. A GFI sensor in the microinverter detects changes in the DC
current and quickly opens (breaks) the circuit when there is a ground fault. These
ground faults can be due to DC wires making contact with grounded racking,
moisture, or overload.
If the condition persists: If the GFI event persists after clearing the condition from
the Envoy, contact your installer or refer to the Troubleshooting Guide at
http://www.enphase.com/support
For further assistance, contact Enphase Energy customer support at
support@enphase.com.
Recommended Action: The microinverters may need to have a software upgrade
in order to be compatible with the selected grid profile. (The selected grid profile
defines operating parameters that are compatible with your utility service.) If a
microinverter software upgrade does not start automatically a few minutes after the
after Envoy has discovered all microinverters, contact Enphase Energy customer
support. Note that the Envoy requires a minimum of 3 bars to communicate
effectively with the microinverters for the software upgrade.
Description: This message displays when the selected grid profile is incompatible
with microinverter software or hardware. This condition can affect your system's
ability to produce power.
If the condition persists: Contact
(support@enphase.com).
Recommended Action: In most cases no action is required. This occurs 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 has detected grid instability. In most cases, this
points to a problem with the utility service (e.g., a power outage). In other cases,
this may be a false positive and a microinverter may be incorrectly reporting grid
instability. In this case a microinverter software upgrade may be needed to help
resolve this issue.
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 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.
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.
