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. If it does not,
the unit may be damaged and requires repair.
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
screen)
D isplays the ambient temperature around
the inverter’s transformer.
In a MATE3-class system display, these
values are given in degrees Celsius.
If any reading does not seem to reflect the
inverter’s temperature or conditions, the unit
may be damaged and requires repair
Output FETs
(in
Temps
screen)
Displays the temperature of the FETs
(Field Effect Transistors) and heat sink.
Capacitors
(in
Temps
screen)
Displays the temperature of the inverter’s
ripple capacitors.
Temperatures
As shown in Table 8, the
Inverter Warnings
screen has an
Inverter Temps
selection for three
internal temperature readings. These readings can affect inverter operations in high
temperatures. Table 9 shows the temperature limits used by each sensor and the effects on
inverter operations.

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.
