The Grid Interface Protection settings are adjustable. However, this is only available to operators with
installer-level access. The reason for this limitation is that there are firm rules concerning the
acceptable voltage range, frequency range, clearance time during power loss, and reconnect delay
when exporting power back to the utility. The rules differ in different locations around the world,
although generally it is expected that the settings cannot be altered by the end user. For this reason,
the installer password must be changed from the default to get access to these settings.
Once this password has been changed, the Grid Interface Protection settings can be accessed by
using the installer password.
See the
Grid Tied mode on page 15 for more information. Also see Default Settings and Ranges.
Firmware Revision
This manual applies to inverter models GS8048A and GS4048A with Revision 001.005.xxx or higher.
Updates to the Radian’s firmware are periodically available. These can be downloaded from the
OutBack website www.outbackpower.com. See page 12.
Default Settings and Ranges
NOTES: Certain items are retained at the present setting even when the inverter is reset to factory
defaults. These items are noted with the letter “X” in the Item column.
Certain items, particularly those in the Auxiliary menus, share common set points. If one of these
items is changed in a mode menu, the change will appear in other menus that use the same set point
Certain menus are only visible when the installer password is used, particularly the Grid Interface
Protection menu. These menus are bordered in the table with a double line of this style:
