I was just wondering what ( if their is any) of connecting batteries in series to increase voltage to 24 or 48.

opps... I mean for the hose batteries for my bus conversion. I've noticed that the higher the voltage ratting on a inverter the higher the price tag. What I was wondering is, is their a good reason to run my batteries at 24 or 48 v or is keeping them at 12 the best solution.

Isn't the '04 originally a 12v system?

sure is... but thats for the power to all the standard 12v equipment (blinkers, headlights, etc..) I not for sure but their should be a way to run a higher voltage battery bank for the house batteries if their is a reason for it. I'm a novice in this area hence the questions.

The answer's -no-, you don't need 24 or 48vdc.You're lucky
to have a 12vdc bus. The earlier MCI's use 24vdc for the
system, so it's easier for some of us to keep it 24 and convert
down to 12 as needed.

Enjoy 12vdc!

Rusty: As Jtng says, be glad u have a 12v bus and go with it. The reason that most of the 24v inverters are more money is that they have larger capacities and more features than many 12v models. The primary reasoning is that large loads require smaller wiring when utilizing a higher voltage.

You can series/parallel a battery bank to achieve numerous voltage outputs and amp hr capacities, but for your purposes, 12 v will serve u just fine and it keeps things fairly simple and straightforward. Having a different voltage house system presents some challenges that you can avoid just by going 12v thruout.

And if you're not very familiar with electrical equipment, count your blessings and stay with the 12 volts.

Multiple system voltages add complexities right when you would rather avoid them. If you needed a very high power inverter would be about the only justification for going to a higher voltage.

If you do stay with 12 volts, you will find that recharging all your batteries from the bus engine generator, your auxiliary generator or shore power is fairly simple.

Good luck on your conversion.

can some one tell me how to wire 6 6v golf cart batteries to get 12v for house batteries

Set the 6 batteries in 3 pairs of 2. On each pair connect the positive post of one to the negative post of the other You now have 3 batteries with an empty negative terminal and 3 batteries with an empty positive terminal. Connect the 3 negativer terminal together (this is the ground for you house battery system. Connect the 3 empty positive terminals together (this is the positive for you house battery system. Make sure you use cable of adeqwuate size for the load you will be drawing off the batteries and a fuse of the proper size to match the cables. Jack
