Error Messages
An error is caused by a critical fault. In most cases when this occurs, the ERROR indicator will
illuminate and the inverter will shut down. (See page 15 for the FXR inverter’s LED indicators.) The
MATE3 system display will show an event and a specific error message. This screen is viewed using
the MATE3 Home screen’s soft keys. (See the MATE3 manual for more instructions.) One or more
messages will display
Y
(yes). If a message says
N
(no), it is not the cause of the error.
Some errors will reset automatically when the cause is resolved. These are noted.
It is possible to clear an error by resetting the inverter. The inverter must be turned off, and then on,
to reset it. Other possible steps are shown below. Each should be followed by resetting the inverter.
Table 8 Error Troubleshooting
Message Causes Possible Remedy
Low Output Voltage
Inverter’s AC regulation cannot be maintained
under high load conditions.
Check loads and measure current draw. Remove
loads as necessary.
AC Output Shorted
Inverter exceeded its maximum surge current
due to severe overload.
Check the loads and wiring. This issue is usually
the result of a wiring problem (a short), as
opposed to a poorly-sized load.
AC Output Backfeed
Usually indicates another AC power source (out
of phase with the inverter) was connected to
the unit’s AC output.
Disconnect the AC OUT wires from the inverter.
Check the wires (not the inverter) with an AC
voltmeter. If an AC source is present, shut it off.
Stacking Error
Programming problem among stacked units.
(Often occurs if there is no master.)
Can also occur if
AC Output Backfeed
occurs.

Check stacking programming and
designation of master. (See page 43.)

Check for output backfeed from an external
source. Disconnect output if necessary.
Low Battery V
11
DC voltage is below low battery cut-out set
point, usually due to battery discharge. This
occurs after 5 minutes at this voltage.
This error can be triggered by other causes. It
can appear along with
Low Output Voltage
,
AC
Output Shorted
, or
AC Output Backfeed
errors.

If this error accompanies other errors, treat
those conditions as appropriate.

If it occurs by itself: Recharge the batteries.
The error will clear automatically if an AC
source is connected and the charger turns on.
High Battery V
10
DC voltage exceeded acceptable level. See
page 27.
Check the charging source. This problem is
usually the result of external charging.
Over Temperature
10
Inverter has exceeded its maximum allowed
operating temperature. See page 64.
Allow the inverter to remain off to reduce the
temperature, or add external cooling.
Comm Faul
t
The inverter has suffered an internal
communication failure.
Contact OutBack Technical Support.
12
Loose DC Neg
Terminals
Loose DC connection on internal power
module.
Tighten all DC connections between inverter and
battery. If this error is not resolved, contact
OutBack Technical Support.
11
Battery Voltage
Sense
Internal sensing has detected battery voltages
below 8 Vdc or above 18 Vdc for a 12-volt model
(or equivalent for higher-voltage models).
If these readings are not correct, contact
OutBack Technical Support.
12
A
C Relay Fault
AC transfer relay damaged. Contact OutBack Technical Support.

11
This error will clear automatically when the cause of the error is resolved. The inverter will begin functioning again when this occurs.
