Inverter Settings (
I
)
Many of the inverter settings in this section apply to all classes of inverters. However, some inverters use different
screens. In cases where screens are different or product-specific, the title indicates the inverter class.

I-1. Search
This function can minimize inverter power draw when no loads are present.
●
Name
— Adjusts the Search mode sensitivity while searching for loads.
Setting this item to zero will disable
Search
mode.
●
Pulse Length
— Adjusts the duration of search pulses (in single AC cycles).
Longer pulses will detect loads more quickly. This consumes more power.
●
Pulse Spacing
— Adjusts the time between
search pulses (in single AC cycles).
Shorter spacing will detect loads more
quickly. This consumes more power.
I-2. AC Input and Current Limit
This menu controls the input current that the inverter can draw. It has
independent settings for two AC sources. It is common for one source to be
the utility grid and the other is an AC generator. The settings are labeled
accordingly. (It also has an independent setting for the inverter’s charger.)
NOTE
: FX-class, FXR-class, and Radian-class inverters interact differently with
multiple AC sources. Note also that several items in this menu are also controlled
in the <
Input Select
>
soft key menu. See the
MATE3s Overview Guide
.
Adjust these settings to the size of the input circuit breaker or conductor.
This is for protection. If combined charging and loads exceed this setting,
the inverter automatically reduces its charge rate. (The loads receive
priority.) If the loads exceed the limit on their own, the charge reduces to
zero. This setting may be assisted by the Input Support function, if present.
Beyond this point, the input breaker may trip. This is accompanied by a
MATE3s event and the warning
Input Amps > Max
.
NOTE
: If multiple parallel inverters are installed with a limited AC source, the combined amperage settings must be less than
the AC input circuit. The MATE3s Profile Wizard can perform this calculation. (See page 45.)
●
Input Type
— (FX-class and FXR-class only;
A
,
C
,
D
) – The inverter has two choices for AC sources:
Grid
or
Gen
. It cannot use both
at once, but it can be switched between them using an external selector switch. The user can select between defined parameters for each
source. (See
I-3
. See page 44 for the effects of the Profile Wizard on this setting.)
●
In FX-class grid-interactive models, this sets the charging format and other parameters.
Gen
prevents the inverter from selling power.
●
Input Priority
— (Radian-class only;
B
) – The inverter can be wired to two AC sources:
Grid
or
Gen
. It can accept either source but
cannot use both at once. However, it will accept one input as a default selection if both sources are active at the same time.
●
Grid
and
Gen Input AC Limit
— Adjusts the inverter’s draw to the size of the appropriate input circuit or source. (See page 45.)
●
Charger AC Limit
— Adjusts the draw of the inverter’s charger. This setting can be limited to avoid accidentally overcharging the
batteries. It should not exceed the maximum charge rate of the battery bank. (See page 44.)
●
Charger Control
— (FXR-class and Radian-class only;
A
and
B
) – Turns off the charger for an individual inverter and prevents it from
responding to global charger commands.
●
Input Support — (FX-class only;
C
) – Enables the Input Support function, if present. Not all FX-class inverters have this function (
D
).
●
NOTE
:
Input Support
is present in Radian- and FXR-class inverters, but is not selectable. It only works in
Support
mode. See

menu, but are used in different models.
I-3a. Grid
and
Gen Input Mode and Limits
(FXR-class and Radian-class)
The inverter will not connect to a source unless specific conditions are met.
Each input has a menu to adjust the conditions. In the Radian, the
Grid Input
Mode and Limits
menu applies to the input labeled
G
rid
.
Gen Input Mode
and Limits
affects the
G
en
input. In FXR inverters, either menu can apply
depending on whether the single input is set to accept
Grid
or
Gen
. See
I-2
.
When the conditions are met, the inverter will accept the source after the designated delay.
●
Input Mode
— Sets this input to one of seven AC input modes (see list). Each mode has specific advantages
for a particular application. (See page 44 for the effects of the Profile Wizard on this setting.)
●
Voltage Limit Lower
and
Upper
— Set the acceptable AC voltage. If the source is within this range, the inverter
accepts it. If it exceeds this range, the inverter disconnects itself. It will return to inverting if that function is active.
●
Transfer Delay
— Sets the duration that the input AC voltage or frequency may exceed limits before disconnection.
This may be preceded by a warning and may be followed by a
Last AC Disconnect
message. (See the
MATE3s
Overview Guide
.)
●
Connect Delay
— Sets the delay period before the inverter begins accepting power from the source. This is intended
to give a generator’s output time to stabilize. It is not the same as the AGS warmup period (see page 27).
GridZero Mode
●
DoD Volts
— Adjusts the lowest allowable battery discharge voltage. Loads will switch to grid power when this setting is reached.
●
DoD Amps
— Adjusts the maximum current (in AC amperes) at which
GridZero
mode draws power from the batteries.
Mini Grid Mode
●
Connect to Grid
— Adjusts the battery voltage setting that causes the inverter to reconnect to the utility grid in
Mini Grid
mode.
●
(Connect)
Delay
— Adjusts the delay period after reaching
Connect to Grid
before the inverter reconnects to the grid.
NOTE
: Certain input modes activate the Grid Support functionality. Some items may not be available (as in
A
). See page 18.

I-3b. Grid
and
Gen Input Mode and Limit
(FX-class only)
The inverter will not connect to an AC source unless specific conditions are
met. When Input Type is set to Grid or Gen in the AC Input and Current
Limit screen (
I-2
), these menus adjust the limits on acceptable source voltage.
Frequency is not adjustable.
●
Lower
and
Upper Voltage Limit
— Set the limits on the acceptable AC voltage. If the
source is within the appropriate range, the inverter will accept it. If it exceeds this range,
the inverter will disconnect itself. It will return to inverting if that function is active.
●
Transfer Delay
— Sets the duration that the input AC voltage or frequency may exceed limits before the inverter disconnects itself. This
may be preceded by a warning and may be followed by a
Last AC Disconnect message
. (See the
MATE3s Overview Guide
.)
●
Connect Delay
— Sets the delay period before the inverter begins accepting power from the source. This is intended to give a
generator’s output time to stabilize. It is not the same as the AGS warmup period (see page 27).
