Grid AC Input Voltage Limits
The inverter will not connect to an AC source unless specific conditions are met. When Input Type is set to
Grid in the AC Input Current Limit screen (Figure 73 on page 78), this menu adjusts the limits on
acceptable voltage for the utility grid. (Frequency is not adjustable.) These limits will vary with the
inverter model. See the
Operator’s Manual for specific acceptance limits.
When the conditions are met, the inverter will accept the grid after a delay of approximately 15 seconds.
To access the
Grid AC Input Voltage Limits menu:
1. Access the Inverter menu as shown in Figure 71 on page 75.
2. Use the control wheel to highlight the Grid AC Input Voltage Limits menu.
Press the button in the center of the control wheel to accept the selection.
3. Use the control wheel to adjust each set point.
Press the button in the center of the control wheel to accept the selection.
This should cause the highlighting to advance to the next set point.
Repeat for each set point.
4. After setting the parameters for each set point, press the
TOP
navigation key to return to the
Main Menu screen.
Figure 74 Grid AC Input Voltage Limits
Set Points:

Lower Voltage Limit:
Sets the low limit on the acceptable AC voltage. If the source is above this
voltage, the inverter will accept it. If it drops below this voltage, the inverter will return to inverting, if
enabled.

Upper Voltage Limit: Sets the high limit on the acceptable AC voltage. If the source is below this
voltage, the inverter will accept it. If it rises above this voltage, the inverter will return to inverting, if
enabled.

Transfer Delay: Sets the duration that the input AC voltage or frequency may exceed limits before the
inverter disconnects itself. This may be preceded by a warning (see page 39), and may be followed by
a
Last AC Disconnect message (see page 54.)
