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 17, which begins on page 63.

Possible Remedy
Check both inputs for a second AC source (utility grid). If the
inverter detects an acceptable AC source, it will not allow

source (due to HBX mode, Mini Grid mode, or similar
programming).
