Description
Description: The Envoy has started a change to the grid profile for the
microinverters. This process may take a few minutes. No action is required.
xx = grid profile name
yy = Regional specification name.
Description: The microinverter is not producing power due to a software
problem.
Recommended Action: Contact Enphase Energy customer support.
Recommended Action: No action is required; it will automatically resume
normal operation momentarily.
Description: The microinverter was reset, either following a successful
software download or by user command.
Recommended Action: No action is required.
Description: The Envoy has received a control request made via the
Envoy interface (Administration > Device Conditions and Controls page) or
via Enlighten. This uncommon condition will occur only during isolated
troubleshooting procedures by Enphase personnel.
Recommended Action: This condition should correct itself. No action is
required.
Description: This rare condition occurs if the microinverter reports an
internal temperature that exceeds its rated range. It reacts by producing
less power to reduce internal temperature. This reflects internal
temperature coming from a sensor inside the microinverter, not the ambient
temperature. Once the internal temperature of the microinverter is once
again within normal limits, it will resume full power production and this event
message will clear.
If the condition persists: Contact your installer or Enphase Energy
customer support at http://www.enphase.com/support
Recommended Action: This condition should correct itself. No action is
required.
Description: This condition may occur at sunrise or sunset, while the
modules are covered with snow, or during very bad weather. This event
indicates that sunlight levels are too low for effective production. Once
sunlight levels increase, the microinverter resumes power production and
this event message will clear.
If the condition persists: Contact your installer or Enphase Energy
customer support at support@enphase.com.
Recommended Action: No action is required unless the condition persists.
Description: An insulation resistance (IR) sensor in the microinverter
measures the resistance between the positive and negative PV inputs to
ground. If either resistance drops below a threshold, the microinverter
raises this condition. This may indicate defective module insulation,
defective wiring or connectors, moisture ingress, etc.
If the condition persists: Contact your installer or refer to the
Troubleshooting Guide at http://www.enphase.com/support.
