Event Messages

The table below 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 and when the event is active. Some messages are specific
to a region and may not appear in regions where the message is not applicable.
Where message is displayed:

Description
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.
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 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/.
