3.0 Setup
Set Final Charge Stage = Float:
The Float Stage is a maintenance
charge mode that maintains a constant voltage while delivering up to the
maximum rated current of the charger in order to power any DC loads
connected to the batteries. Most three stage chargers
fi
nish the charge mode
in Float and remain in Float as long as an AC source is available on the input
of the charger. The Float voltage is determined by the battery type selected
in menu 03B Battery Type.
The difference between Float and Multi is that in the Float mode, there is no
“Full Charge” mode, as described in the previous “Multi” section.
Why should I use the Float mode?
Float mode is typically used when the
charger is the only charge source connected to the batteries. This mode will
maintain the batteries at the
fl
oat voltage. If using
fl
ooded batteries and the
charger is in
fl
oat for an extended period the water level should be checked
every two to three weeks for proper levels.
Set Final Charge Stage = Silent:
Silent mode stops charging once it
transitions from Absorb mode to “Silent”. Once the charger enters the Silent
mode it will monitor the battery voltage and start charging once the batteries
fall to the “DC Volts to Rebulk” setting. Once the batteries reach the “Set DC
Volts to Rebulk” under 03G Final Charge Stage setting the charger will start
the charge cycle over in the Bulk mode and then transition to Absorb. After
the Absorb cycle the charger will again transition to the Silent mode and the
charger will continue this cycle.
Set DC Volts to ReBulk -
When ”Silent” mode is selected you must also
set the DC voltage set point where the charger restarts the Bulk mode. This
setting should be the lowest DC volts that you will allow the batteries to fall
to before starting a new Bulk cycle. Typically the lowest DC volts the batteries
are allowed to fall is 12.0 to 12.2VDC, (12-volt systems) 24.0 to 24.4VDC
(24-volt systems) and 48.0 to 48.8VDC (48-volt systems) respectively.
Default Setting:
Set DC Volts to ReBulk = 12.0
Why should I use the Silent mode?
Silent mode is typically used when
an alternate charge source is available, and able to fully charge or
fi
nish the
charge cycle after the Absorb stage. A major difference between Multi mode
and Silent is that Silent mode returns to the Bulk mode instead of Float mode.
In Silent mode you can also adjust the Rebulk set point in order to allow the
alternate charge source to provide more of the battery charging.

04 AGS Setup
This menu is used to setup only the functions related to the ME-AGS-N (Au-
tomatic Generator Start - Network version), which automatically starts and
stops the generator on the following conditions:
Gen Run VDC
- starts and stops the generator based on battery voltage.
Gen Run Time
- starts and stops the generator based on time of day.
This feature uses the ME-ARC clock to determine start and stop times.
Gen Run Amps
- starts and stops the generator based the AC amp load
on the inverter in Invert mode.
Gen Run SOC
- starts and stops the generator based on the SOC read-
ing from the ME-BMK.
Gen Run Temp
- starts the generator based on the interior temperature,
or A/C thermostat and stops the generator after the set time.
Info:
For detailed information on the ME-AGS-N, refer to it’s Owner’s
Manual (part number: 64-00005).
