Recommended Action:
Contact Enphase Energy customer support.
Description:
The microinverter is not producing power due to a software problem.
Bad Meter
Recommended Action:
Contact Enphase Energy customer support.
Description:
The metering functions of the Envoy-S have failed.
Calibration Corrupted
Recommended Action:

Description:
Metering calibration is incorrect.
CommandedReset
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.
ControlRequest
Recommended Action:
No action is required.
Description:
The Envoy has received a control request. This uncommon condition
will occur only during isolated troubleshooting procedures by Enphase personnel.
CriticalTemperature
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

DcPowerTooLow
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 extreme 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

.
DCResistanceLoPowerOff
Recommended Action:
Clear this error
via Enlighten’s Current Issues page. Note
that the condition will not clear after sensor reset if the cause of the failure is still
present.
If the condition persists, contact your installer.
Description
: An 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 stops power production and raises this condition. This
may indicate defective module insulation, defective wiring or connectors, moisture
ingress, etc. Although the cause may be temporary, this microinverter condition
persists until the sensor is manually reset.
If the condition persists
: If the event persists after clearing the condition, contact
your installer.
