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 profi 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 profi 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 specifi 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 specifi 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.
CTRL: 03 Gen Control
03 Gen Control is used for controlling a standby generator that is connected
to the system and using the optional ME-AGS-N module. Once the AGS-N
