Here are some clever ways to set up your rv solar power system.
Rv battery wiring series vs parallel.
I ll go through each of these wiring methods below.
Note that you should never combine different amp hour 6v batteries.
I have attached a picture that depicts how batteries are run in series and in parallel.
You will simply need to continue the pattern for 4 batteries.
Connecting batteries in series adds the voltage of the two batteries but it keeps the same amperage rating also known as amp hours.
Combining two 6v rv batteries only increases the voltage but not the amp hours like when you wire two 12v rv batteries in parallel.
For more information on wiring in series see connecting batteries in series or our article on building battery banks.
See the differences between parallel vs serial wiring connections and why i chose a series parallel configuration for my rv solar installation.
Hence when charging these batteries it is important to utilize a charger that satisfies the 12 volt capacity that is necessary for both the 6 volt batteries connected in series.
Wiring batteries in series parallel combination.
In our illustration we show two 6v batteries with 225ah wired together.
In contrast batteries connected in a parallel configuration are able to increase the amp hour capacity of your batteries at the same voltage.
How to wire batteries in series.
But you still will only have 225ah.
When you combine two of them in series you get 12v.
Rv batteries series vs parallel.
The result would be a battery bank that produces 6v and 450ah.
Connecting in parallel increases amp hour capacity only the basic concept is that when connecting in parallel you add the amp hour ratings of the batteries together but the voltage remains the same.
The good news is you can combine series and parallel wiring with 6 volt batteries so you can combine 4 or more and keep the voltage at 12 for your rv but increase the amp hours.
Why use 6 volt batteries or 12 volt batteries.
For example these two 6 volt batteries joined in series now produce 12 volts but they still have a total.
A 6v 225ah agm deep cycle rv battery will weigh around 71 lbs.
Series will be the negative post of one battery to the positive post of the next battery while with a parallel setup all of the positive terminals will be connected and all of the negative.
This video will explain a lesser know fact about using the series 6 volt bat.
