Positive connection becomes the Positive terminal of the 48V bank. Similarly, the four
Negative terminals of Batty Banks 1 to 4 are paralleled (connected together) and this
common Negative connection becomes the Negative terminal of the 48V battery bank.

Fig. 7.4: Series-Parallel Connection
Figure 7.4 shows a series – parallel connection consisting of four 24V, 200 Ah Battery
Banks to form a 48V, 400 Ah battery bank. Two 24V, 200 Ah Battery Banks 1 and 2 are
connected in series to form a 48V, 200 Ah Battery Banks (String 1). Similarly, two 24V,
200 Ah Battery Banks 3 and 4 are connected in series to form a 48V, 200 Ah Battery Bank
(String 2). These two 48V, 200 Ah Strings 1 and 2 are connected in parallel to form a
48V, 400 Ah bank.
!
CAUTION!
When 2 or more batteries / battery strings are connected in parallel and are
then connected to an inverter or charger (See Figs 7.3 and 7.4), attention
should be paid to the manner in which the charger / inverter is connected to
the battery bank. Please ensure that if the Positive output cable of the battery
charger / inverter (Cable “A”) is connected to the Positive battery post of the
first battery bank (Battery Bank 1 in Fig 7.3) or to the Positive battery post of
the first battery string (Battery Bank 1 of String 1 in Fig. 7.4), then the Negative
output cable of the battery charger / inverter (Cable “B”) should be connected
to the Negative battery post of the last battery bank (Battery Bank 4 as in Fig.
7.3) or to the Negative Post of the last battery string (Battery Bank 4 of Battery
String 2 as in Fig. 7.4). This connection ensures the following:
