Functions

The items in this section are operations common to all Radian 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 remote

system display. (See the MATE3 System Display and Controller Owner’s Manual for instructions on

locating these set points.) The default settings and ranges of adjustment are listed beginning on

page 47 of this manual.
Each distinct operation is accompanied by a symbol representing the inverter and that function:

The symbols for each operation may have other features depending on the operation.

Inverting

The Radian 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 two transformers and two high-frequency H-Bridge FET modules to achieve

the required high-wattage output. When not in use, the dual design allows half the inverter to shut
down for lower idle consumption.
The Radian 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 being supplied by an
AC source.

Low Battery Cut-Out: This feature prevents the inverter from draining the batteries completely. It will stop
functioning and give a

Low Battery V error when the DC voltage drops below a specified level for 5 minutes.

This appears as an Event on the MATE3 system display, as described in the MATE3 Owner’s Manual. It is one of
the Error messages described on page 40. 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.

TRANSFER

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.
