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 4/0 AWG, the battery interconnects should be 4/0 AWG.

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.

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

only.

as a single battery, but an Ah rating equal to the sum of the individual

connected. In a parallel configuration, the battery bank has the same voltage

 

batteries. See below.
