CTRL: 01 AC In Control
The
01
AC In Control
menu has four different conditions in which the inverter/charger connects to
an incoming AC power source. Only one may be selected—multiple conditions can be set up and
enabled, but only one can be active at a time.
Info:
The top status line of the alternates the
inverter/charger status with a secondary
AC IN status when AC is present, but is
not
connecting as a result of a setting made in
the SETUP menu.
Example:
AC is present, but
Time Connect
has been selected from the
01 AC In 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 displays “
Inverting
” and the secondary
status displays “
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 button’s
03B
Low
VAC Dropout
setting, and between 50 Hz to 70 Hz for domestic
models; 40-60 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
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 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.
•
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 on page 27 for a complete explanation of the
Connect/Disconnect
time
menu
settings.
•
VDC Connect:
Incoming AC only connects when the DC battery voltage falls below the
Connect
volts setting in the SETUP menu’s
02D AC In – Volts DC
menu item. Disconnects from
incoming AC when the DC battery voltage rises above the
Disconnect
volts
setting, also from
the
02D AC In – Volts DC
menu. See SETUP menu 02D on page 28 for a complete explanation
of the
Connect/Disconnect
volts
menu
settings.
•
SOC Connect:
Incoming AC only connects when the battery bank SOC falls below the
Connect
setting in the SETUP menu’s
02E AC In – SOC
menu item. Disconnects from incoming AC
when the battery bank SOC rises above the
Disconnect
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 on page 28 for a complete explanation of the
Connect
SOC menu settings.
Info:
If
SOC Connect
is selected and the incoming AC connects, the router issues
a one-time “ Start Bulk” command to the inverter/charger. This ensures the charger
enters the Bulk/Absorb charge cycle regardless of battery voltage.
•
AC In – Disabled:
Disconnects incoming AC when selected. This setting prevents the incoming
AC from connecting to the inverter/charger.
