Grid-Tie Sell
The following descriptions apply to grid-interactive inverter models only (both FX-class and Radian-class). In
other models, these menus are inoperative.
IMPORTANT: FX-class grid-interactive models only
The grid-interactive function can sell power using the input connection. This
function only operates if
Grid is selected in the AC Transfer Control menu. It
does not function if Gen is selected.
This menu controls the limits of the inverter’s “grid-tie” or grid-interactive function. See the inverter
Operator’s Manual for an explanation of the grid-interactive function and how it relates to the regular
charging process.

Set Points:
 Grid-Tie Enable – Enables or disables the inverter’s grid-interactive
function. If Y is selected, the function is turned on. If N is selected,
the function is turned off.
NOTE: If the MATE3’s Enable Auto Grid-Tie Control menu item
(see page 128) is set to Y (yes), Grid-Tie Enable may be turned on
according to MATE3 and FLEXnet DC automatic criteria, even if it is
manually turned off here.
Grid-Tie Enable will switch to Y.
 Sell Voltage – Sets the operating point for the grid-interactive
function. When a renewable source raises the batteries above this
point, the inverter exports power in order to bring the voltage back
down. (The inverter cannot import AC power to raise the batteries
to this level.) This means the Sell feature only functions when
excess DC power is available. (However, if the charger is operating,
it can also sell power using other charger set points. See the
inverter Operator’s Manual for more details.)
 Grid-Tie Window – Sets the requirements that the utility grid must
meet for the grid-interactive function to work. If the voltage and
frequency are within the ranges specified in each selection, the
inverter can sell power. Otherwise, the selling function will not
operate. The unit will display a message in the
Sell Status menu
(see page 39). Two selections are available, IEEE and user. Specific
settings for each set point are listed in the inverter Operator’s
Manual.
~ The IEEE selection has narrower settings than the user setting.
~ IEEE is required by most utilities in the United States. (For
American models, its voltage and frequency criteria are preset
to the requirements of UL1741 and IEEE 1547.)
