Firmware Revision; Table 21 Charge Currents For Calculations - Outback Power Systems FXR2012E Operator's Manual

Calculating Limits
If other numbers are needed than those featured in Table 20, the results can be calculated. Do not use
the calculations on page 33, due to charger efficiencies and other factors.
To calculate the chargers and settings:
6. 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 21.
C = the maximum AC input of the appropriate inverter model. This is taken from Table 21.
7. Select a value for D and perform the following calculation.
D = the
Charger AC Limit
value uses fewer chargers and turns off all others. A lower value, or 6, leaves more chargers on.
8. Perform the following calculation.
__ A __ (C) ÷ D = E
B
E = the number of chargers to use. This number should be rounded down in all cases.
9. Adjust the master inverter's Charger AC Limit setting to equal D.
10. Turn off the chargers for all inverters that exceed E. In a system stacked on the HUB
communications manager, chargers on higher-numbered ports should be turned off first.
Chargers should be turned off by setting the Charger Control menu item to
tables beginning on page 76 to locate this command in the menu structure.)
