Outback FX-R Series Operator Manual

Specifications

To calculate the chargers and settings:

1. Look up the values for A, B, and C.

A = the battery bank’s maximum charge current (in Adc) from the battery manufacturer.

B = the maximum DC output of the appropriate inverter model. This is taken from Table 20.

C = the maximum AC input of the appropriate inverter model. This is taken from Table 20.

2. Select a value for D to be used in the following calculation.

D = the Charger AC Limit setting. This value must be 12 or higher. (See page 63.) A higher value

uses fewer chargers and turns off all others. A lower value, or 12, leaves more chargers on.

3. Perform the following calculation.

E = the number of chargers to use. This number should be rounded down in all cases.

4. Adjust the master inverter’s Charger AC Limit setting to equal D.

5. Turn off the chargers for all inverters that exceed E. In a system stacked on the HUB

comm

unications manager, chargers on higher-numbered ports should be turned off first. Charge

should be turned off by setting the Charger Control menu item to Off. (See the menu tables

beginning on page 66 to locate this command in the menu structure.)

NOTES

Certain items are retained at the present setting even when the inverter is reset to

factory defaults. These items are noted with the letter “X” in the Item column.

Certain items, particularly those in the Auxiliary menus, share common set points. If one of

these items is changed in a mode menu, all menu items with this set point will show the

same change.

Certain menus are only visible when the installer password is used, particularly the

Grid

Interface Protection

menu. These menus are bordered in the table with a double line of this

style:
