Parallel Wiring

Wiring the batteries in parallel increases the total run time the bat-
teries can operate the AC loads. A parallel connection combines
overall battery capacity by the number of batteries in the string. Even
though there are multiple batteries, the voltage remains the same.
In the example below (Figure 15), four 12 VDC/100 AHr batteries
are combined into a single 12 VDC/400 AHr battery bank.

Series-Parallel Wiring

A series-parallel confi guration increases both voltage (to match the
inverter's DC requirements) and capacity (to increase run time for
operating the loads) using smaller, lower-voltage batteries. In the
example below (Figure 16), four 6 VDC/200 AHr batteries are com-
bined into two strings resulting in a 12 VDC/400 AHr battery bank.
