Message Definition Possible Remedy
Fan Failure
The inverter’s internal cooling fan is not
operating properly. Lack of cooling may result
in derated inverter output wattage.
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
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.
Transforme

D isplays the ambient temperature around the
inverter’s transformer.
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.

Temperature Events
The temperature sensor readings shown in Table 8 are used to limit the inverter operation in high
temperatures.

GT Warnings
This screen is also available under
Inverter Warnings
. The GT (grid-tie) warnings in Table 10 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 11) or a regular warning (see Table 8), depending on conditions.
