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 76 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 67 and 71 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 completely. When the
DC voltage drops below a specified level for 5 minutes, the inverter will stop functioning. The MATE3 will
give a Low Battery V error. This is one of the error messages described on page 62. It appears as an event
on the MATE3 system display.
This function 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 adjustable.

Low Battery Cut-In: The recovery point from Low Battery Cut-Out. When the DC voltage rises above this
point for 10 minutes, the error will clear and the inverter will resume functioning. This item is adjustable.

Connecting an AC source for the inverter to charge the batteries will also clear a low battery error.
