AC Source Acceptance
The input source must meet the following specifications to be accepted. This is true in all
modes except
Grid Tied
:

Voltage (
GRID
input selection): 108 to 132 Vac

Voltage (
GEN
input selection): 108 to 140 Vac

Frequency (both input selections): If the output frequency is set to 60 Hz (default), the input
acceptance range is 54 to 66 Hz. If output frequency is set to 50 Hz, the input range of acceptance is
45 to 55 Hz.

See the menu tables which begin on page 66 for programming information for these items.
When these conditions are met, the inverter will close its transfer relay and accept the input
source. This occurs after a delay which is specified below. If the conditions are not met, the
inverter will not accept the source. If it was previously accepted and then rejected, the inverter
will open the relay and return to inverting power from the batteries. This occurs after a specified
transfer delay, which is an adjustable menu item.
IMPORTANT:
The inverter’s output voltage can be adjusted to a different nominal value for a particular region. (See
page 24.) If this occurs, the source acceptance range should be adjusted to match this nominal value or
the inverter may not accept the new source normally.

The voltage limits can be adjusted to allow (or exclude) a source with weak or irregular voltages.
These items
are adjustable in a MATE3-class system display (
Grid AC Input Mode and Limits
or
Gen AC Inpu
t Mode and Limits
). The settings are titled
Voltage Limit Lower
and
Upper
. There
can b
e side effects to changing the range of allowed voltage
s.

Each of the AC input selections has a settable
Connect Delay
. This is intended as a warmup period
whi
ch allows an input source to stabilize before connec
tion.

The default setting for the
Grid
selection is 0.2 minutes (12 seconds).

The default setting for the
Gen
selection is 0.5 minutes (30 seconds).
These items
are adjustable in the appropriate system display menu (
Grid AC Input Mode and Limits
or
Gen AC Input Mode and Limits
).
NOTES
:

The
Grid Tied
input mode does not use these voltage, frequency and time acceptance limits. It uses
the
Grid Interface Protection
and
Grid Support
settings in
stead. (See pages 17 and 39 for
more
informatio
n.) The inverter may not accept AC power if it meets the settings noted here but do
es not
meet the setti
ngs in these two menus.

Certain input modes such as
Mini Grid
may prevent the inverter from accepting AC power even if
electri
cal conditions are met. (See pag
e 19.)
Several items external to the inverter ma
y prevent the inverter from accepting AC power even if
electrical conditions are met. Some examples are the
High Battery Transfer
,
Grid Usage Time
, or
Load Grid Tr
ansfer
functions, all of which are operated by the system display. Another exam
ple is
the
AC
I
NPUT
hot key menu of a MATE3-class system display, which can order all inverters to
discon
nect when set to
Drop
.
