Cabling & Hook-up Configurations
Several smaller batteries can be connected to create a battery bank of
substantial size. You can connect batteries in three ways: in parallel, series, or
series–parallel ("cross-tied").
To make a larger battery bank, connect individual batteries with heavy cables.
The actual size of the cable depends on whether the batteries are connected in
parallel or series. Generally, the cables should not be smaller than the inverter
cables—if the main cables are 4/0AWG, the battery interconnects should be 4/
0AWG.
The best configuration is to connect the batteries in series and parallel—a
configuration often called "cross-tying." This requires additional cables but
reduces imbalances in the battery bank and can improve the overall
performance. Consult your battery supplier for more information regarding
the hook-up configuration required for your system.

Parallel Connection

Batteries are connected in parallel when all the positive terminals of a group of
batteries are connected and then, separately, all the negative terminals are
connected. In a parallel configuration, the battery bank has the same voltage as
a single battery, but an Ah rating equal to the sum of the individual batteries.
