Description
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 Enphase Energy customer support at
http://www.enphase.com/support
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
AC mains. 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.
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.
