3.0 Setup
CTRL: 02 CHG (Charge) Control
02 CHG Control
enables you to set the Charge mode to
Multi-Stage
,
Force
Float
, or to
Restart 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
CHG Control
menu. The charger can be forced into the Float mode or you
can start the Bulk mode using the
Force Float
or
Restart Bulk
settings from
the CTRL button’s
02 CHG Control
menu.
• Multi-Stage
–
This charge pro
fi
le starts in Bulk mode (maximum cur-
rent). It transitions to the Absorption stage (constant voltage). When the
Absorption voltage is reached (as determined by the SETUP button’s
03E
Absorb Done
menu), it transitions to the
fi
nal charge stage as selected
in the SETUP menu’s
03G Final Charge Stage
menu item.
Info:
Multi-Stage
must be selected in order for the
Final Charge
Stage
setting to be used.
• Force
Float
–
This charge pro
fi
le forces the charger to stay in Float mode
as long as AC is present and the charger is active.
Force Float
is most
often used when another source of charging such as PV, wind, or hydro
is available to keep the batteries at or above the
fl
oat voltage. If AC is
disconnected and then reconnected, the charger will go directly to Float
mode and will not initiate a Bulk or Absorption charge cycle.
CAUTION:
Using
the
Force Float
setting may not fully charge the
batteries. Most batteries require a Bulk and Absorption charge cycle
in order to fully recombine the electrolyte in the batteries and bring
the speci
fi
c gravity to the proper level. Be sure to check with your
battery manufacturer before using this setting.
Info:
If
Silent
is selected from the SETUP menu’s
03G Final Charge
Stage
menu item, you can override this selection with
Force Float
to temporarily
fl
oat the batteries.
• Restart
Bulk
– This selection restarts the Bulk cycle from any stage in
the charge cycle. The
Restart 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
Restart Bulk
setting automatically defaults back to the
Multi-Stage
setting once the inverter/charger status displays “
Bulk
Charging
”.
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 button’s
03 Charger Setup
menu to ensure the batteries
are fully charged at the end of a regular multi-stage charge cycle.
Check with the battery manufacturer for proper battery charger
settings.
CAUTION:
Frequently restarting the Bulk cycle may result in over-
charging of the batteries.

to the system and using the optional ME-AGS-N module. Once the AGS-N
