AC Voltage Out
Of Range
AC Voltage Out Of
Range
Recommended Action: This condition should correct itself. No action is
required.
Description: The microinverter reports that the AC voltage coming from
the utility is either too low or too high as specified by applicable regional
standards.
When a microinverter detects the voltage out of range condition, it does
not produce power (per regulation) until the utility voltage returns within
acceptable limits for several minutes (time varies by region). If during that
time the utility voltage again goes beyond acceptable limits, the timer
restarts.
If the condition persists: Contact your installer or refer to the
Troubleshooting Guide at http://www.enphase.com/downloads/.
Applying grid
profile xx from
regulatory
specification yy
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.

Bad Flash Image
Description: The microinverter is not producing power due to a software
problem.
Recommended Action: Contact Enphase Energy customer support.
Commanded
Reset
Commanded Reset
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.
Control Request
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.
Critical
Temperature
Critical Temperature
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. Once the internal temperature
of the microinverter is once again within normal limits, it will resume full
power production and this error message will clear.
If the condition persists: Contact your installer or refer to the
Troubleshooting Guide at http://www.enphase.com/downloads/.
DC Resistance
Low
DC Resistance Low
Recommended Action: No action is required unless the condition
persists.
Description: A 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 issues due to moisture, overload, defective circuit, live wires
making contact with ground wire, or other conditions.
If the condition persists: Contact your installer or refer to the
Troubleshooting Guide at http://www.enphase.com/downloads/.
