Operation
Description of Functions
All items identified as settable or adjustable have set points which can be accessed using the remote system display. (See the system display manual for instructions on locating these set points.) The default settings and ranges of adjustment are listed near the end of this book, beginning on page 47.
Each function is accompanied by a symbol representing the inverter and that function:
TRANSFER
AC IN
DC
AC OUT
These items represent the input from the AC source, the output to the AC loads, DC functions (inverting, charging, etc), and the transfer relay. Arrows on each symbol represent current flow.
The symbols for each function may have other features depending on the function.
Inverting
A GFX inverter uses a transformer and a
The 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 in conjunction with the batteries and the inverter, but not in place of the batteries.
Certain features will affect the inverter’s operation. These features only operate when the inverter is generating AC power on its own. They do not function when the inverter is supplied by an AC source.

¾AC Output Voltage: The inverter’s AC output can be turned up or down by a certain amount to adjust for conditions. This item is adjustable.

The high battery
This function is intended to protect the inverter’s output and loads. Continuing to invert on a high DC voltage may produce a distorted waveform. Note that the high battery
