Troubleshooting
Message Definition
Fan Failure The inverter's internal cooling fan is not
operating properly. Lack of cooling may result
in derated inverter output wattage.

Temperatures

As shown in Table 9, the Inverter Warnings screen has an Inverter Temps selection for three internal
temperature readings. These readings can affect inverter operations in high temperatures. Table 10
shows the temperature limits used by each sensor and the effects on inverter operations.
Effect
Over Temperature error
Reduced charging or selling
Fan turns on
Fan turns off

GT Warnings

This screen is also available under Inverter Warnings. The GT (grid-tie) warnings in Table 11 indicate
why a grid-interactive inverter has stopped selling. These warnings are caused when the grid exceeds
one of the settings in the Grid Interface Protection menu. A GT warning may accompany a
Disconnect message (see Table 12) or a regular warning (see Table 9), depending on conditions.

Definition
The AC source has exceeded Grid Interface Protection frequency levels.
The AC source has dropped below Grid Interface Protection frequency levels.
The AC source has exceeded Grid Interface Protection voltage levels.
The AC source has dropped below Grid Interface Protection voltage levels.
Possible Remedy
Turn the battery disconnect off, and then on, to
determine if the fan self-tests. After this test,
contact OutBack Technical Support for the next
13
step. (The next step will depend on the results
of the test.)
NOTE: The system can continue to operate if the
inverter can be run at reasonable levels. External
cooling may also be applied.
In the MATE3, these values are given in degrees
Celsius.
If any reading does not seem to reflect the
inverter's temperature or conditions, contact
OutBack Technical Support.
