Setup
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 feature if the AC source is from a
generator—the generator power may not be available if an AC In feature is activated;
because 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 27 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.
CTRL: 02 Charger Control
The 02 Charger Control menu enables you to set the charge mode to Multi-Stage, Start Float, or
to Start Bulk. Most of the time the charger should be left in the Multi-Stage setting, but to override
this setting use the CTRL button and the 02 Charger Control menu. The charger can be forced to
start the Float or Bulk charge mode using the Start Float or Start Bulk settings from this menu.
•
Multi-Stage: This charge profi le causes the charger to automatically operate thru the multi-
stage (Bulk, Absorption, and Final Stage) charge cycles. When AC is connected and the charge
mode begins¹, the inverter’s battery voltage is monitored to determine the charging stage. If the
battery voltage is low (≤12.8 VDC/12-volt models, ≤25.6 VDC/24-volt models, or ≤51.2/48-volt
models), the charger begins Bulk Charging. If the battery voltage is high (≥12.9 VDC/12-volt
models, ≥ 25.7 VDC/24-volt models, or ≥ 51.3/48-volt models), the charger skips the Bulk
and Absorb charge stages and goes directly to the fi nal charge stage (Multi-Stage, Float, or
Silent) as selected in the SETUP: 03F Final Charge Stage menu item.
Note¹ – If the SETUP: 03C Battery Type selection is CC/CV, once AC connects and the charge
mode begins, the charger enters the Constant Current charge mode. If the CTRL: 01 AC In
Control setting is “SOC Connect,” or if the SETUP: 03D Absorb Done setting is “SOC”, then the
charger will always enter the Bulk Charge mode once AC is connected and charging begins.
• Start Float: This selection restarts the Float charge cycle from any stage in the charge cycle
as long as the charger is active.
Info: The Start Float selection automatically defaults back to the Multi-Stage setting
once the inverter/charger status displays “Float Charging” (or “Silent” if battery type
CC/CV is selected).
Info: If battery type CC/CV is chosen, the Start Float selection transfers the charger
to Silent mode—unless “Hold CV Chg Volts” is selected, then the charger enters the
Constant Current charge mode.
