Setup
CTRL: 02 CHG (Charge) Control
02 CHG Control
enables you to set the charge mode to
Multi-Stage
,
Start Float
, or to
Start Bulk
.
Generally, the charger should be left in the
Multi-Stage
setting, but to override this setting use
the CTRL button and the
02
CHG Control
menu. The charger can be forced to start the Float or
Bulk mode using the
Start Float
or
Start Bulk
settings from the
CTRL: 02 CHG Control
menu.
Info:
If either
Start Float
or
Start Bulk
is selected and no AC is present or is qualifying,
or the
CTRL: 01 AC In Control
menu is set to
AC In - Disabled
, the remote displays
“
AC Not Present
”.
• Multi-Stage
– This selection causes the charger to automatically operate through the multi-
stage (Bulk, Absorption, and Final Stage) charge cycles. When AC is connected and the charge
mode begins
¹
, the inverter’s battery voltage is monitored to determine the charging stage.
If the battery voltage is low, the charger begins Bulk charging. If the DC voltage is high,
the charger skips the Bulk/Absorb charge stages and goes directly to the
fi
nal charge stage
(Multi-Stage, Float, or Silent) as selected from the
SETUP: 03G Final Charge Stage
menu.
Note¹
–
When AC is connected and the charge mode begins, if the
03C Battery Type
is
CC/
CV
the charger enters the Constant Current mode.
• 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:
When the battery type is
CC/CV
: the charger enters Silent mode if
Start Float
is
selected; or, the charger enters Constant Current charge mode if
Hold CV Chg VDC
is
selected.
• Start
Bulk
– This selection restarts the Bulk cycle from any stage in the charge cycle as long
as AC is present and the charger is active. The
Start Bulk
setting is useful when a full multi-
stage charge cycle does not bring the speci
fi
c gravity of the batteries to the proper level.
Info:
The
Start Bulk
selection automatically returns to
Multi-Stage
once the status
displays “
Bulk Charging
” (or “
Constant Current”
if battery type
CC/CV
is selected).
Info:
If the current charge mode is Bulk or Absorption, and then
Start Bulk
is selected,
“
Already in Bulk/Abs
” displays on the remote.
Info:
If battery type
CC/CV
is chosen and the charger is in Silent charge mode, the
Start Bulk
selection transfers the charger to Constant Current mode.
Info:
If you have to continually restart the bulk cycle in order to bring the batteries to
full charge, check the settings from the
SETUP: 03 Charger Setup
menu to ensure the
batteries are fully charged at the end of a regular multi-stage charge cycle.
CAUTION:
Frequently restarting the Bulk charge cycle may result in overcharging of
the batteries.
CTRL: 03 Gen Control
03 Gen Control
is used for controlling a standby generator that is connected to the system and
you are using the optional ME-AGS-N controller. See Sections 7.1 and 7.2 for information on set-
ting up the ME-AGS-N using the ME-ARC’s SETUP and CTRL buttons.
CTRL: 04 PT Control
04 PT Control
is used for controlling a charge controller that is connected to the system. See Sec-
tions 10.1 and 10.2 for information on setting up the PT charge controller using the ME-ARC’s
SETUP and CTRL buttons.
