Installation Manual

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 qualiﬁ 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

qualiﬁ 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 beneﬁ 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.
