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 GS7048E 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
GS7048E 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 (see inside the front cover of this manual).
Although the GS3548E 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 GS3548E.
The Module Select menu options are displayed as part of Table 16, which begins on page 67.
