Basic Setup Programming
6–24 976-0043-01-01
13C Input Upper Limit VAC
This menu item sets the highest voltage at which the inverter is allowed to
connect to either AC1 or AC2 inputs. When this voltage is reached the
inverter disconnects from the grid or generator and provides power to the
loads from the batteries as long as the inverter selection in menu
01A Inverter is ON or SRCH.
The inverter reconnects to the AC source when the voltage drops below
this setting.
Guidelines for setting this menu item:
•
Ensure this value is within the upper limits of any AC operated
equipment connected to the inverter.
13D Input Lower Limit VAC
This menu item sets the lowest voltage at which the inverter is allowed to
connect to either AC1 or AC2 inputs.
This setting determines the voltage level at which point the inverter starts
drawing power from the batteries to aid to the grid power (AC1) or GEN
(AC2) power depending on which one is being used to meet the demands
of the loads.
When the AC voltage reaches this level, the inverter stops battery
charging and operates in parallel (in the inverter mode) with the AC
source, to aid the utility power to meet the demands of the load. This
reduces the loading effect on the AC source.
If the voltage drops below this level, the inverter disconnects the AC
source and powers the load directly from the batteries as long as the
inverter’s selection in
01A Inverter is ON or SRCH. This is part of the
AC support feature.
Guidelines for setting this menu item:
•
Ensure this value is within the lower limits of any AC operated
equipment connected to the inverter.

CAUTION: Damage to Loads
Adjusting upper and lower AC voltage parameters allows the
higher and lower voltages than the inverter output to pass
through to connected AC loads. Ensure that all connected AC
loads will not be damaged by the higher and lower settings.
