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.
