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.
