Message Shown on
Events and Inventory
Screens
Description
ACFreqChangeTooFast
(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 power
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 grid.
AcFrequencyOOR (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 power
provider is either too low or too high as specified by applicable regional standards.
AC frequency is the frequency at which voltage varies on the power grid.
Frequency Out of Range events are usually transient and self-correcting by the
power provider.
When the microinverter detects an out of frequency condition, it must remain offline
until the grid has been within acceptable limits continuously for a short period of
time (seconds to minutes, varies by region). If, during that time, the grid 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
enphase.com/support
.
AcMonitorErr
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.
ACVoltageAverageHi (AC
Voltage Average Too High)
Recommended Action
: No action is required unless the condition persists.
Description
: The microinverter reports that the average AC voltage coming from
the grid 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
enphase.com/support
.
AcVoltageOOR (AC
Voltage Out Of Range)
Recommended Action:
This condition should correct itself. No action is required.
Description
: The microinverter reports that the AC voltage coming from the grid 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 grid voltage returns within acceptable limits
for several minutes (time varies by region). If during that time the grid voltage again
goes beyond acceptable limits, the timer restarts.
If the condition persists:
Contact your installer or refer to the Troubleshooting
Guide at

number 800-00(xxx-xxx)
Recommended Action:
No action is required.
Description:
