Troubleshooting

Error Messages

An error message is caused by a critical fault. In most cases when this occurs, the unit will shut down and the inverter’s ERROR LED (see page 11) will illuminate. See the system display manual for instructions on viewing errors. One or more messages will display yes in the MATE system display; Y in the MATE3. If a message says no (or N), it is not the cause of the error.

Error screens can only display errors; they cannot clear them. 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 (although it is still necessary to reset the inverter).

Possible Remedy

Check loads and measure current draw. Remove loads as necessary.

Check stacking programming and designation of master. (See page 25.)

Check for output backfeed from external source. Disconnect output if necessary.

Shut off the inverter to reduce the temperature, or add external cooling.

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 external AC source is connected and the inverter’s charger comes on.

Check the AC voltage on the inverter input terminals. If AC voltage is not present, problem is external. If AC voltage is present, the unit may be damaged. Contact OutBack Technical Support (see inside front cover of this manual).

Check the charging source. This problem is usually the result of external charging. This error will clear automatically if conditions are removed.

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.
