I need help w/ 6V batteries and converter and inverter

Another option is modify your fridge to run 12VDC or get one that's already 12V. It would probably be cheaper. convert your lights to 12VDC, and your chargers can probably already run 12VDC. Then all you need is a 80$ battery charger from Walmart; no transfer switch, no inverter, etc. If you really must have the blowdryer, or 120V for for anything else, you could get one of these for 129$.

I declined to answer about your wiring diagram because I don't want to steer you wrong. It will depend on what transfer switch you get (if you get one) and which inverter/charger you get. And if there is info available on the internet for the devices you choose. It would be easy for me to draw a block diagram for you now, but it would be just as easy for it to be wrong and end up getting you hurt. Why don't you post links to the devices you have in mind, and we can go from there?
(that is, if you don't decide to go 12V)

Strantor,
So I'm gonna stick with the inverter and not change to 12V. Its already set up that way so I'm gonna leave it.

Set up....
2 - 6V AMG batteries
Inverter - I'd like - http://www.donrowe.com/inverters/ms_series.html
the 2000 watt 50 amp charger.
or...
http://www.batterystuff.com/inverters/pro-true-power-2000ps.html

But if I get an inverter and then a charger I'd go something like this - http://www.batterystuff.com/batteries/ssw-2000-12a.html
or.....
http://www.donrowe.com/inverters/sa_2000k_112.html
or......
http://www.donrowe.com/inverters/elite_2000.html
anyways they are all 2000 watt, just not sure of the brand yet. Still looking.
But if I could get the wattage down under 2000, that would help with the price.

Plus a charger which I believe would just be a converter.

I guess let me narrow it down, haha.
If this helps write back.
I'll do more research tonight.

Thanks

1hp = 746W, therefore 1/8hp = 93.25W

That's just for the motor, plus there's a light inside and possibly a fan.

Keep in mind, it doesn't (shouldn't) run constantly so it is a pretty low consumption device.

Strantor,
I was thinking about running the fridge the whole time we would be camping to not have to dig in the ice chest all the time.
or are you saying that as long as the fridge is shut it should stay cool and not have to continue running?

Thanks

yeah if you ever watch a fridge, you'll see it cycle. it's got a thermostat that will kick on when temp goes below X and turn off when it gets above Y. It's hard to miss when you have an old noisy clunker fridge like I do.

Startup power can be a factor of 2 or 3. The trick will be to insure your inverter has sufficient surge power to handle that. I've never seen a startup power rating for a refridgerator, so here again you might need to run some experiments.

So I was ready to buy this inverter/charger but it is a hardwire.
Do you think I should do a hardwire direct to the AC box with a transfer switch? But the inverter has a transfer switch in it?
I was just planning on running an extension cord from the inverter to the plug on the camper.
Not sure what is best.
Please advise.

Here is the inverter/charger

To be honest, I am leery to answer your questions because I've never done what you are doing, so I am not speaking from experience. I don't want to tell you something wrong, and have you waste a bunch of money. If this were cheap stuff I would be less hesitant.

Well, you've read my disclaimer so its all on you now. Don't come back after a week and say "damn you strantor, 1600$ later it doesn't work."

That being said, I have used tripp-lite products before and was happy with them. I think you've found a good unit there, and if I had your credit card I would probably buy it for myself.

I would run the generator output straight to the inverter, and run the inverter output into your breaker panel. Essentially just insert this unit somewhere between the generator and the breaker panel.

Thanks
Ill let you know how it goes.
Actually I'll probably ask some more questions first. :)
