I rest my case about not being well informed.

There was a debate here on a thread that I was involved in about using 12 VDC Deep Discharge batteries versus a series of 6 VDC batteries for the House battery bank.

There was one person that just didn't GET it and he insisted that his one 12 VDC battery was a far better solution than having two 6 VDC batteries.

However, the bottom line is that each RV owner can do what they want based on their experiences and knowledge, after all it's THEIR RV.

I have learned over the years that regardless of how it is explained, some people get it and some people don't.

Yeah, right. Like YOU knew that!

Yes sir I do.
In 40 plus years of RVing and and 24 years of installing PV systems in RV's I have learned a few things.
I have also learned that some listen and learn and others, as Dr4Film said, never do.

Let's stop the personal comments. That's not what this forum is for. Please get back to the topic.
Thanks

You know, I tried to be nice and inject a little light humor. But I see that effort was wasted.

What's ironic is that I OVER ESTIMATED the possible run time by 50%!

Funny thing, by never learning I was able to sustain a 44 year career in software development. A field that demands constant learning. Change that 'never learn' to 'never agree' and you got it.

I left electronics behind when I went to work for IBM as a systems programmer at the tender age of 18, a very long time ago. I learned new technologies and managed to stay in the game while most of my cohorts fell victim to technological obsolescence. I retired when I wanted to.

If you or anyone you love is a diabetic and uses a glucose meter, insulin pump or computer based tracking system there's a good chance they're using a product I worked on. Better hope I learned something.

Can we call a truce now?

Ok, ok!

I actually like the fact that most of us actually have strongly held opinions. Let's go have a beer and get to it!

I think you can have a residential fridge along with a correctly sized battery bank and super solar system. I actually think we should all have super solar systems on our RVs because solar is perfect for us (see, I have an opinion).

But it's hard to have both for the residential fridge. Not hard so much as expensive. Dang RV fridges are so efficient on propane that you almost have to rule out anything else. That said, though, if you full time in a very sunny area (like the southern US) you can probably get away with it for not too many dollars. You have to plan. I would say why do you think you want the res fridge rather than the RV? Beyond the fact that a res fridge typically has more features the simple objective a fridge is to keep things cold or frozen. So do that as efficiently as possible?

IMHO if you boondock all the time you need to think Norcold or Dometic. Too many power variables to ensure you never have warm stuff. And that's the goal.

Atwood is marketing evaporative fridges that use helium instead of hydrogen. Helium does not burn.

This is a link to the replacement xref. http://www.atwoodmobile.com/images/r...-cross-ref.pdf. Nothing to replace a Norcold 1200 series yet.

Here's a comparison between Dometic and the Atwood Helium. Comparable performance except the Atwood does not have auto-start after a power interruption.

BTW, Atwood has some new air conditioners that look pretty good.

Or if you install more batteries and bigger inverter/converter and solar panels and have an auto start the generator, you can last at least longer depending on how much additional charging and storage systems you have installed?

Do I pretty much have the simple picture?

We have a older (2000) MH with 4 6V batteries and 100 W solar panel and a Magnum MS2812 pure sine wave inverter (this was a replacement for a Xantrex Freedom 458)

Our travel days are typically ~7 hours total.

Our Samsung RF197 is rated at an average power consumption of ~100W.

We only turn on the generator when we need it to run the A/C while traveling.

Our batteries are only slightly discharged when we finish a day's drive.

I question the sanity of whoever decided that having an RV refer shut down after a power failure was OK. (Are you listening Atwood?). That's a show stopper as far as I'm concerned.

So you're saying that your solar panel and alternator do NOT keep up with the refer draw?

I guess the question is:

Does the alternator charge the House batteries (at all)?
