Event Messages
The following table lists messages that the Envoy local interface displays to indicate various conditions.
These messages appear on the computer screen when your computer is connected to the Envoy local
interface.
Where message is displayed:
AC Frequency
Changing Too
Fast
AC Frequency
Changing Too
Fast
Recommended Action: No action is required unless the
condition persists.
Description: AC frequency is the frequency at which voltage
varies on the utility grid. The microinverter reports that this value
is changing more rapidly than allowed. Frequency Changing Too
Fast events are usually transient and self-correcting by the utility.
AC Frequency
Out Of Range
AC Frequency Out
Of Range
Recommended Action: This condition should correct itself. No
action is required.
Description: The microinverter reports that the frequency coming
from the utility is either too low or too high as specified by
applicable regional standards.
AC frequency is the frequency at which voltage varies on the
utility grid. Frequency Out of Range events are usually transient
and self-correcting by the utility.
When the microinverter detects an out of frequency condition, it
must remain offline until the utility has been within acceptable
limits continuously for a short period of time (seconds to minutes,
varies by region). If, during that time, the utility again exceeds or
falls short of acceptable limits, the timer must restart and the
microinverter may not begin producing power for an additional
short period following the last out-of-bounds condition.
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 microinverter is temporarily unable perform
power conversion.
If the condition repeats or persists: Contact your installer to
arrange for the installation of a replacement microinverter.
Recommended Action: No action is required unless the
condition persists.
Description: The microinverter reports that the average AC
voltage coming from the utility over the past 10 minutes was too
high for the configured grid profile.
If the condition persists: Contact your installer or refer to the
Troubleshooting Guide at http://www.enphase.com/support.
