Wiring Batteries in Parallel
Wiring the batteries in a parallel configuration increases the current of the battery string. This is
commonly used in 12 volt configurations. The voltage of the battery bank remains the same as an
individual battery. Parallel configurations extend the run times of the AC loads by providing
increased current for the inverter to draw from. In a parallel configuration, all of the negative battery
terminals are connected together and all of the positive battery terminals are connected together.

Wiring Batteries in Series-Parallel
Wiring the batteries in a series-parallel configuration increases the
current and voltage of the
battery bank. Series-parallel wiring is more complicated and care should be taken when wiring these
banks.
To construct a series-parallel battery bank follow these instructions:
Step 1
 First wire the batteries in series (voltage adds) with the positive terminal of one battery
connected to the negative terminal of the next battery to meet the inverters DC input
requirements.
 Repeat this step for the next battery string.
 Two identical strings of batteries are now wired in series.
