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
electricity network. 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 electricity network.
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
electricity network is either too low or too high as specified by applicable
regional standards.
AC frequency is the frequency at which voltage varies on the electricity
network. Frequency Out of Range events are usually transient and self-
correcting by the electricity network.
When the microinverter detects an out of frequency condition, it must
remain offline until the electricity network 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/downloads/.
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
Troubleshooting Guide at http://www.enphase.com/downloads/.
