Programming
FLEXnet DC Advanced Control
IMPORTANT:
See the FLEXnet Owner’s Manual for detailed information about the
FNDC functions.
This menu allows certain advanced functions to be programmed into the FLEXnet DC (FNDC). The
FLEXnet DC is required to be part of the system before any of these functions can be used.
Set Points:

Enable Charge Termination Control - allows the battery charging to be stopped for all
inverters on the system, once the charging parameters of the FLEXnet DC have been met.
(See page 112 for these parameters.) Options are N (no) or Y (yes).

Enable Auto Grid-Tie Control - If grid-interactive inverters are present on the system, this
control allows their grid-interactive function to be turned off at midnight each night. If
grid-interactive inverters are not present, this item is inoperative. Options are N (no) or
Y (yes). When Y is selected, "grid-tie" mode will be enabled on grid-interactive inverters
anytime the battery monitor signals that charge parameters have been met.
NOTE: When grid-tie mode is enabled with this function, the Grid-Tie Enable menu item
(see page 101) will change to Y (yes). The inverter will become capable of selling even if
the function had been previously turned off.
The next two items are both related to the system indicators on the Home screen (see pages 33
and 151) and are titled Battery Status on the screen.
