Setup
CTRL: 01 ACIn Control
01 ACIn Control
menu has four different conditions in which the inverter/charger will connect to
an incoming AC power source. Only one may be selected at any one time—multiple conditions can
be enabled, but only one can be active.
Info:
Before the inverter allows the AC input to connect to the AC source (grid or
generator), the incoming AC must be quali
fi
ed by the inverter/charger (voltage is
below the high AC input requirements, above the
SETUP: 03B VAC Dropout
setting, and
between 50 Hz to 70 Hz for domestic models—40 to 60 Hz for export models).
Info:
The top line of the LCD display alternates the inverter/charger status with a
secondary AC IN status when AC is present (not connecting as a result of a selection
made in the SETUP menu).
Example:
AC is present, but
Time Connect
has been selected from the
01 ACIn Control
menu and the current time of day is 6PM. The SETUP menu’s
02C AC In - Time
current
setting is
2AM-8AM
. The current time of 6PM is outside the connect time, so the inverter/
charger will not connect to the incoming AC until after 2AM. The primary
status will
display “
Inverting
” and the secondary
status will display “
Time Connect
” to let you know
the reason that incoming AC has not connected.
• Auto Connect
– Automatically connects to incoming AC power when the incoming AC is
quali
fi
ed by the inverter/charger (voltage is below the high AC input requirements, above the
SETUP: 03B VAC Dropout
setting, and between 50 Hz to 70 Hz for domestic models—40 to
60 Hz for export models).
Info:
The
Auto Connect
setting must be selected if the incoming AC source is a
generator. There is no bene
fi
t from using the AC In Control
feature if the AC source
is from a generator—the generator power may not be available if an
AC In feature is
activated. Also, when the generator is turned on (autostarted or manually), it may be
prevented from connecting because the criteria to allow the AC input to connect (AC In
is based on time, VDC, or SOC) may not have been met.
Note:
This is true unless you are using an inverter that has two independent AC inputs—
one for grid and the other for generator (i.e., MSH4024RE)—because the AC In Control
features only work with the GRID IN (AC1) input
.
• VDC
Connect
– Only allows the incoming AC to connect when the DC battery voltage falls be-
low the
Connect
volts setting in the SETUP menu’s
02D AC In - VDC
menu item. Disconnects
from incoming AC when the DC battery voltage rises above the
Disconnect
volts setting, also
from the
02D AC In - VDC
menu. See SETUP menu
02D
for more information on the
Connect/
Disconnect Volts
menu settings.
• Time
Connect
– Incoming AC only connects when the time of day is between the
Connect
and
Disconnect
time settings in the SETUP menu’s
02C AC In - Time
menu item. See SETUP
menu
02C
for more information on the
Set Connect/Disconnect
time menu settings.
• SOC
Connect
– Incoming AC only connects when the battery bank State of Charge (SOC)
falls below the
Connect
SOC setting in the SETUP menu’s
02E AC In - SOC
menu item. Discon-
nects from incoming AC when the battery bank SOC rises above the
Disconnect
SOC
setting,
also from the
02E AC In - SOC
menu. This feature requires the optional ME-BMK (battery
monitor) to be installed. See SETUP menu
02E
for more information on the
Set Connect SOC
menu settings.
• ACIn - Disabled
– Disconnects incoming AC when selected. This setting will prevent incom-
ing AC from connecting to the inverter/charger.
