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.

Description
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.
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/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.
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/support.
