To calculate the chargers and settings:
1.
Look up the values for A, B, and C.
A = the batte
ry bank’s maximum charge curren
t
(in Adc) from
the battery manufacturer.
B = the maximum DC output of the appropriate invert
er
model. This i
s taken from Table 16.
C = the maximum AC input of the appropriate inve
rter
model. This i
s taken from Table 16.
2. Select a value for D to be used in the following
cal
culatio
n.
D = the Charger AC Limit
setting. This value must
be
12 or hig
her. (See page 61.) A higher value uses fe
wer
cha
rgers and turns off all ot
hers. A lower value, or 12,
leaves mo
re 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.
5. Turn off the chargers for all inverters that exceed E.
In a system stacked on the
HUB communication
s
manag
er, chargers on higher-numbered
ports
sho
uld be turned off first. Chargers shou
ld be
turned off by setting the Charger C
ontrol
menu item
to Off. (See t
he menu tables beginning on page 63 to
locate this command in the menu structur
e.)
