B-6 Battery Wiring Confi gurations
The battery bank must be wired to match the inverter’s DC input voltage. In addition, the batteries
can be wired to provide additional run time. The various wiring confi gurations are:
B-6.1 Series Wiring
Wiring batteries in series increases the battery bank’s output voltage. A series connection combines
each battery in a string until the total voltage matches the inverter’s DC requirement. Even though
there are multiple batteries, the capacity remains the same. In Figure B-1 below, two 6 VDC/200
AH batteries are combined into a single string resulting in a 12 VDC, 200 AH bank.

B-6.3 Series-Parallel Wiring
A series/parallel confi guration increases both voltage (to match the inverter’s DC requirements)
and amp-hour capacity (to increase run-time for operating the loads) using smaller, lower-voltage
batteries. In Figure B-3 below, four 6 VDC/200 AH batteries are combined into two strings resulting
in a 12 VDC, 400 AH battery bank.
B-6.2 Parallel Wiring
Wiring batteries in parallel increases the battery bank’s amp-hour capacity, which allows the AC
loads to operate for a longer time. A parallel connection combines the number of batteries in the
string to increase overall battery capacity; however, the voltage remains the same. In Figure B-2
below, two 12 VDC/100 AH batteries are combined into a single 12 VDC, 200 AH battery bank.
