Event Messages
The following table lists messages that the Envoy can produce to indicate certain conditions.
These messages appear on screen when your computer is connected to the Envoy local interface.
Where message is displayed:
Description
Home Screen
Inventory Screen
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

ACMonitorError ACMonitorError
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.
AC Voltage
Average High
AC Voltage Average
High
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
