Description of Inverter Operations
The items in this section are operations common to all FXR inverters. These are used in most
or all of the input modes described in the preceding section.
Some of the items in this section are functions which can be manually selected, enabled, or
customized. Other items are general topics or applications for the inverter. These items may
not have their own menus, but their activity can still be influenced or optimized by changing
certain settings.
Any of these items may need to be adjusted so that the inverter is best matched to a particular
application. The operator should review these items to see which are applicable.
All items described as settable or adjustable have set points which can be accessed
using the system display. The default settings and ranges of adjustment are listed in the menu
tables which begin on page 66 of this manual.
Inverting
This is the FXR inverter’s primary task. The inverter converts DC voltage from batteries into AC
voltage that is usable by AC appliances. It will continue to do this as long as the batteries have
sufficient energy. The batteries can be supplied or recharged from other sources, such as solar,
wind, or hydroelectric power.
The inverter’s design uses a transformer and a high-frequency H-Bridge FET module to achieve
the required high-wattage output. The inverter can deliver the rated wattage continuously at
25°C. The maximum output is derated at temperatures exceeding 25°C. See pages 57 and 61
for these wattages.
Measure the total load wattage so that it does not exceed the inverter’s capacity. The inverter
cannot maintain its AC voltage under an excessive load. It will shut down with a
Low Output
Voltage
error.
DC and AC Voltages
The FXR inverter requires batteries to operate
. Other sources may not maintain DC voltages
that are consistent enough for the inverter to operate reliably.
CAUTION: Equipment Damage
Do not substitute other DC sources in place of the batteries. High or irregular voltages may
damage the inverter. It is normal to use other DC sources with the batteries and the inverter,
but not in place of the batteries.
The following items will affect the inverter’s operation. These are only used when the inverter is
generating AC power on its own.

Low Battery Cut-Out
: This function prevents the inverter from draining the batteries complete
ly.
When the DC voltage drops below a specified level for 5 minutes, the inverter
will stop functioni
ng.
The sy
stem display will give a
Low Battery V
error. This is one of the errors on page 52. It appea
rs
as an eve
nt on a MATE3-class system display
.
This fun
ction is intended to protect both the batteries and the inverter’s output. (Continuing
to invert
on a low
DC voltage may produce a distorted waveform.) This item is adjustabl
