Wiring Batteries in Parallel
Effect
Wiring the batteries in a parallel configuration increases the current of the battery
string. The voltage of the battery bank remains the same as an individual battery.
“Parallel” configurations extend the run times of the AC loads by providing
increased current for the inverter to draw from. In a parallel configuration, all the
negative battery terminals are connected together and all the positive battery
terminals are connected together.
Wiring example
Figure B-3 is an example of how to wire batteries in a parallel configuration.
