Each 6 volt battery pair operates as a single 12 volt battery.
Does putting two 6v solar panels in series create 12v.
So if you connect two solar panels with a rated voltage of 40 volts and a rated amperage of 5 amps in series the voltage of the series would be 80 volts while the amperage would remain at 5 amps.
To produce a 12 volt output two 6 volt deep cycle batteries must be wired in series positive to negative.
Say you have 2 x 100 watt solar panels and a 12v battery bank.
You can then connect each 6 volt pair in parallel with another pair to create a larger 12 24 or 48 volt battery bank.
Wiring batteries in series parallel combination.
This is called a series parallel configuration.
After these clarifications let s see how the series connection takes place.
In a series parallel combo configuration the batteries are wired per the diagram below and the result would be a doubling of the voltage and doubling of the capacity.
Let s look at a numerical example.
Two 12v rv batteries with 100ah is going to be manageable for one person fit in regular rv battery storage space and be way more affordable.
In our illustration we show two 6v batteries with 225ah wired together.
The result would be a battery bank that produces 6v and 450ah.
Putting panels in series makes it so the voltage of the array increases.
By connecting multiple solar panels in series we increase the system voltage.
Since each panel is 12v and the battery bank you want to charge is 12v then you need to parallel your system to keep the voltage the same.
