Warning Messages
A Warning message is caused by a noncritical inverter fault. When this occurs, the inverter will not
shut down, but will display a fault LED. One or more messages in this menu will change from
N
to
Y
.
A warning is also accompanied by an event message (see page 61).
Some warnings can become errors if left unattended. Frequency and voltage warnings are meant to warn
of a problematic AC source. See the inverter Operator’s Manual for more information on troubleshooting a
specific warning.
Figure 30
Inverter Warnings and Temperatures
Screen Items:
AC Freq Too High: The AC source is above the acceptable
frequency limit and prevents connection.
AC Freq Too Low: The AC source is below the acceptable
frequency limit and prevents connection.
Voltage Too High: The AC source is above the upper
acceptable voltage limit and prevents connection.
Voltage Too Low: The AC source is below the lower acceptable
voltage limit and prevents connection.
Input Amps > Max: AC loads are drawing more current from
the AC source than allowed by the input setting.
Temp Sensor Bad: An internal inverter temperature sensor
may be malfunctioning. This is indicated by an unusual
Transformer, Output FETs, or Capacitors reading.
Comm Fault: Probable failure on inverter’s control board which
has interrupted internal communications.
Fan Failure: The inverter’s internal cooling fan is not operating
properly. Lack of cooling may result in derated output wattage.
Soft Keys:
Inverter Temps screen, with the readings
for the inverter’s internal temperature sensors. One sensor is
attached to the main transformer, another is on the heat sink for
the Field Effect Transistors (FETs), and one is on the filter
capacitors. Normally all three sensors read approximately the
same. An unusually high or unusually low reading on one sensor
indicates a defective sensor. Contact OutBack Technical Support
if necessary (see inside front cover of this manual).
The screen is different for Radian-class inverters. Radian inverters
consist of twin power modules (right and left) with independent
sensors and readings for each module.
IEEE Warnings screen, with reasons why the
inverter might stop selling power, and
Y or N status messages.
This item and screen are only available in the Radian-class
inverters and are not visible in FX-class inverters.
NOTE: These messages,
AC Freq Too High, AC Freq Too Low,
Voltage Too High, and Voltage Too Low, have the same names
as those shown on page 62. However, these items do not have
the same function. They are only active in the Radian-class
inverter’s Grid Tied input mode. They only indicate whether the
inverter sells power, not whether it disconnects. (See the Radian
Operator’s Manual for limits on selling.)
