Battery Cabling
The cables which connect the individual batteries together to make a larger battery bank should be
connected together with heavy cables. The actual size of the cable depends upon whether the
batteries are connected in parallel or series. Generally, the cables should not be smaller than the main
battery cables to the inverter.If the main cables are 4/0 AWG, the battery interconnects should be 4/0
AWG.
It is usually preferable to first connect the batteries in series and then in parallel when connecting
smaller batteries together. The best configuration is to connect the batteries both in series and parallel
a configuration often called “cross-tying” This requires additional cables but reduces imbalances in the
battery and can improve the overall performance. Consult your battery supplier for more information
regarding the hook-up configuration required for your system.
