Table 8 Warning Troubleshooting
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.
Transformer
(in Temps menu)
Displays 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. 10
Output FETs
(in
Temps menu)
Displays the temperature of the FETs
(Field Effect Transistors) and heat sink.
Capacitors
(in
Temps menu)
Displays the temperature of the inverter’s
ripple capacitors.
Temperature Events
The temperature sensor readings shown in Table 8 are used to limit the inverter operation in high
temperatures. Table 9 shows the effects on the inverter and the temperature used by each sensor to
cause the effect.
