In theexample below (Figure 20), four 6 VDC/200 AHr batteries are com-bined into two strings resulting in a 12 VDC/400 AHr battery bank.Figure 19, Parallel Battery Wiring12 volt battery bank (total capacity = 400 AHrs)overcurrentprotection12 volts(100 AHrs )12 volts(100 AHrs )12 volts(100 AHrs )12 volts(100 AHrs )To12 VDCInverterParallel WiringWiring the batteries in parallel increases the total run time the bat-teries can operate the AC loads. A parallel connection combinesoverall battery capacity by the number of batteries in the string. Eventhough there are multiple batteries, the voltage remains the same.In the example below (Figure 19), four 12 VDC/100 AHr batteriesare combined into a single 12 VDC/400 AHr battery bank.
