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

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/.
