Battery Cabling and Hook-up Configurations
Battery Series Connection
When batteries are connected with the positive terminal of one battery to
the negative terminal of the next battery, they are connected in series. In a
series configuration, the battery bank has the same Ah rating of a single
battery, but an overall voltage equal to the sum of the individual batteries.
See below.
Battery Series-Parallel Connections
As the name series-parallel implies, both the series and parallel
configurations are used in combination. The result is an increase in both the
voltage and the capacity of the total battery bank. This is common with all
battery-inverter system voltages. The smaller, lower voltage batteries are
first connected in series to obtain the necessary voltage, and then these
“batteries connected in series” sets are connected in parallel to increase the
battery bank capacity. See below.
