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 C-4 is an example only of how to wire batteries in a parallel
configuration. The Sine Wave Plus is not available in a 12-volt unit.
