Generator Support Settings
Generator support allows power to be automatically drawn from the batteries to
assist an AC generator to support heavy loads (loads that exceed the available
current from the generator).
Generators have a limited output current and it is possible to reach this limit when
operating heavy loads. The XW Inverter/Charger is designed to assist the
generator when heavy current demands load down the generator by supplying
additional power from the batteries.
In addition, the battery charger can back off its charging current to the batteries so
the combined load of the charger and load support does not exceed the capacity of
the generator or trip its output breakers or fuses.
For default settings, see “Gen Support Menu” on page B–5.
Auxiliary Output Settings
The Aux menu allows you to enable and configure the auxiliary output. The
auxiliary output provides 12 Vdc at 250 mA to power a relay, indicator light or
alarm.
Note:
Running and Start-up (Peak) currents are limited to the maximum current limits
of the inverter.
Table 3-7 Gen Support Menu Values
Setting Description
GenSupp Mode Turns the Generator Support feature on and off.
GenSupp Amps Sets the generator load level at which the XW Inverter/Charger
supplies power from the batteries to support the generator.
Table 3-8 Aux Menu Values
Setting Description
Manual Aux Sets the state of the Auxiliary Output. ManualOn or ManualOff allow
manual control of the Auxiliary Output. When set to Automatic, a
trigger source can then be selected.
Active Lvl Sets the mode (polarity) of the aux output. When triggered, the output
can be active high (12 Vdc output turns on) or active low (output is
high until the trigger turns it off).
Trigger Src Selects the desired condition (Trigger Source) to activate the Aux
Output. The Trigger Source options are LowBattV, HighBattV,
LowBattTemp, HighBattTemp, and Fault.
Trigger Level Sets the voltage or temperature level (depending on the selected
trigger source) at which the aux output is activated. If the selected
Trigger Source is a Battery Voltage, the range also varies according to
the nominal battery voltage of your system.
