9.5 Series-Parallel connection of batteries (24V)
Figure 9.6
Four 12V batteries connected in series
– parallel
Multiple strings of batteries can be wired in parallel to increase the capacity.
Figure 9.6
shows a
battery bank with two strings of batteries. Each string consists of two 12V batteries in series. For
example, if wiring four 12V/150Ah batteries like as shown in Figure 9.6, then each string will have
a total capacity of 24V/150Ah. By paralleling these strings, the total capacity would be 24V/300Ah.
Because of this, it is mandatory that the batteries are identical.
Each parallel string can also consist of 4x6V batteries to make 24V per string as shown in
Figure
9.5
. Remember that the negative cable from the controller to the battery should be placed at the
opposite end of the battery bank.
