Appendix C - Battery Information

C.3 Battery Wiring

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 con¿ gurations are:

C.3.1 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 ¿ gure B-1 below, two 6 VDC/200

AH batteries are combined into a single string resulting in a 12 VDC, 200 AHr bank.

C.3.3 Series-Parallel Wiring

A series/parallel con¿ 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-volt-

age batteries. In ¿ gure B-3 below, four 6 VDC/200 AH batteries are combined into two strings

resulting in a 12 VDC, 400 AH battery bank.

C.3.2 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 ¿ gure B-2 below, two

12 VDC/100 AH batteries are combined into a single 12 VDC, 200 AH battery bank.
