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.
Message Causes
Inverter's AC regulation cannot be maintained
Low Output Voltage
under high load conditions.
Inverter exceeded its maximum surge current
AC Output Shorted
due to severe overload.
Usually indicates another AC power source (out
AC Output Backfeed
of phase with the inverter) was connected to
the unit's AC output.
Programming problem among stacked units.
Stacking Error
(Often occurs if there is no master.)
Can also occur if AC Output Backfeed occurs.
DC voltage is below low battery cut-out set

Low Battery V
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.
DC voltage exceeded acceptable level. See

High Battery V
page 27.
10
Inverter has exceeded its maximum allowed
Over Temperature
operating temperature. See page 64.
Comm Fault The inverter has suffered an internal
communication failure.
Loose DC Neg Loose DC connection on internal power
module.
Terminals
Internal sensing has detected battery voltages
Battery Voltage
below 8 Vdc or above 18 Vdc for a 12-volt model
Sense
(or equivalent for higher-voltage models).
AC Relay Fault AC transfer relay damaged.

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

Possible Remedy
Check loads and measure current draw. Remove
loads as necessary.
Check the loads and wiring. This issue is usually
the result of a wiring problem (a short), as
opposed to a poorly-sized load.
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.

Check stacking programming and
designation of master. (See page 43.)

Check for output backfeed from an external
source. Disconnect output if necessary.

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.
Check the charging source. This problem is
usually the result of external charging.
Allow the inverter to remain off to reduce the
temperature, or add external cooling.
Contact OutBack Technical Support.
Tighten all DC connections between inverter and
battery. If this error is not resolved, contact
OutBack Technical Support.
If these readings are not correct, contact
OutBack Technical Support.
