Battery Cabling and 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.

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 cable should not be smaller than the inverter

cables—if the main cables are 120 mm

, the battery interconnects should be

120 mm

The best configuration is to connect the batteries in series and parallel. 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.

Battery 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. See

below.
