Table 15 Chargers On And Current Settings; Table 16 Charge Currents For Calculations - Alpha OutBack Power Radian Series Operator's Manual

Specifications
To calculate the chargers and settings:
Look up the values for A, B, and C.
1.
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 16.
C = the maximum AC input of the appropriate inverter
model. This is taken from Table 16.
Select a value for D to be used in the following
2.
calculation.
D = the Charger AC Limit setting. This value must be
12 or higher. (See page 61.) 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.
A
(C) ÷ D = E
B
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.
Turn off the chargers for all inverters that exceed E.
5.
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 Off. (See the menu tables beginning on page 63 to
locate this command in the menu structure.)
