Generator, external
fan, etc. fails to start
when signal is
provided by AUX
output.
AUX output is not connected.
Test the generator or device to confirm functionality. Test the
appropriate AUX terminals with a DVM. (If the RELAY AUX
terminals are in use, test for continuity. If the 12V AUX terminals
are in use, test for 12 Vdc.) If the proper results are present when
the menu indicates the function is
On (and the device still does
not work), then there is an external connection problem. If the
proper results are not present with the function
On, the AUX
circuit may be damaged. Contact OutBack Technical Support.
Wrong AUX terminals have
been programmed.
MATE3 system display only: Confirm that the AUX menu that was
programmed matches the terminals that are in use. The
Auxiliary
Output menu programs the 12V AUX terminals. The Auxiliary
Relay menu programs the RELAY AUX terminals.
Wrong AUX terminals are in use.
If generator or external device requires 12 Vdc, confirm the 12V
AUX terminals have been connected. The RELAY AUX terminals
do not provide voltage.
Advanced
Generator Start
(
AGS) fails to
activate when
conditions are met
(or starts when
conditions are not
met).
MATE3 system display only:
AGS
function does not work if
another valid input is present.
Check both inputs for a second AC source (utility grid). If the
inverter detects an acceptable AC source, it will not allow
AGS.
This is true even if it is internally disconnected from the source
(due to
HBX mode, Mini Grid mode, or similar programming).
MATE3 system display is not
present.
AGS programming is located in the MATE3 and cannot function if
the MATE3 is removed.
Other AUX functions are in
operation.
Gen Alert or another AUX function may try to start or stop the
generator using the wrong criteria. Make sure all other AUX
functions are disabled.
AGS or Gen Alert
functions start the
generator, but the
inverter does not
accept the power
and shuts off the
generator again.
The inverter’s
GRID input is in
use and the input priority is set
to
GRID.
If the input priority is set to
GRID and the
GRID terminals are
energized, an automatically controlled generator will shut down.
This could indicate that the generator has been wired to the
GRID
input, or it could indicate that another AC source is active on
the
GRID input while the generator is using the GEN input.
The
GEN input must be the only terminals in use when
automatically controlling a generator.
Either the
GRID or GEN input can be used when manually
controlling a generator.
Module Select
The GS8048A uses two high-frequency H-Bridge FET modules. The dual design allows half the inverter
to shut down for lower idle consumption. Normally this is automatically selected. If one module fails
or if troubleshooting is otherwise needed, the module selection can be performed manually. The
GS8048A can be directed to use a single, specified module (left or right), or it can be directed to turn
on both modules continuously. This procedure should only be performed if directed by OutBack
Technical Support

.
Although the GS4048A has only a single module, this command is still available. The default setting is
Left, which is the location of the module. Do not change this setting in the GS4048A.
The Module Select menu options are displayed as part of Table 16, which begins on page 65.
