amps 20C Float Done Amps.
20A Refloat High Volts DC
This menu item sets the upper battery voltage level that triggers the float
charge. When this level is met or exceeded, the unit turns on the charger
and directs the excess DC power to the AC loads and attempts to maintain
the battery at the float voltage level.
20B Refloat Low Volts DC
This menu item sets the lower battery voltage level to which the batteries
are allowed to discharge. When the batteries drop to or below this level
the charger will turn ON and provide a float charge to the batteries. It will
not initiate a bulk charge.
20C Float Done Amps AC
This menu item is used by the charger to determine the AC current level
(after the 20D Must Float Time Min period has been reached) when it
should change back to the Silent mode.
As the batteries charge, their current demands decrease. This setting
specifies at what point the current supplied to the batteries is allowed to
decrease to in order to trigger the Silent mode.
The 20C Float Done Amps AC setting is usually set to 1% of the total
battery bank capacity.
To calculate the 20C Float Done Amps AC:
1.
Multiply the battery amp hours by 1%. This is the DC Max Charge
Rate changed to float done amps expressed in DC terms.
2.
Convert the DC Max Charge Rate to AC amps by dividing the DC
Max Charge Rate by 4 for a 24-volt system or 2 for a 48-volt system.
3.
The result is the approximate amp setting that should be entered for
the 20C Float Done Amps AC menu item.
For stacked inverters, use half the battery amp-hour rating in the
calculations.
Note:
This information is provided for guidance only. Variations in battery
chemistry, as well as site specific environmental considerations, mean that you
should consult your system designer or battery manufacturer for specific
recommendations for appropriate battery voltage and current settings. An
amp-hour meter (e.g., Xantrex TM500A) would be useful to verify your
settings are correct to maintain a proper charge on the batteries.
