Battery Cabling and Hook-up Configurations

This guide for use by qualified installers only.

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.
