Wiring batteries in a series increases the total battery bank output voltage. A
series connection combines each battery in a string until the voltage matches the
inverter’s DC requirement. Even though there are multiple batteries, the capacity
remains the same. In the example below , two 6VDC/200Ah batteries are
combined into a single string-resulting in a 12VDC /200Ah bank.
b). Parallel Wiring
Wiring the batteries in parallel increases the total run time the batteries 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 , four 12 VDC/100Ah
batteries are combined into a single 12VDC/400AH battery bank.
