Hi Jim

[1]Yes the poster did ask a simple question.

Unfortunately a reply had a basic & misleading error

the poster of that error had it pointed out to him with the suggestion he correct it

He did not follow that suggestion but tried & still tries to justify it ., despite ALL atempts to explain why it is wrong

So who is the pendent???

[2]Yes many do come here seeking advice & IMHO it is important that they recieve CORRECT advise

 Not misleading advise or info

But when someone continues to justfy their incorrect advise ,WHO is the pendent??

The above posts are very relevant to that incorrect info

[3] Yes , I ,for one always attempt to do that, but sometime the message can be very hard to get through to some one who is not prepared to or is unwiiling to even think they may wrong!! As IN THIS CASE

[4]I agree,  lacking knowledge on any subject does not make a person dumb but when some one refuse to accept they are wrong ,despite the evidence ,is that stupid, dumb, obstinate etc???????

 

Peter

IMHO, the time to correct an error is when it is first made, otherwise more errors can evolve

Finally IF someone claims to have some expertise in a particular area[in this case, low voltage  DC & solar etc] they should be prepared for their peers to comment [GOOD OR BAD]

 I think you may have meant "pedant". "Pendent" relates to pending.

Perhaps I am now the pedant.  winkwinkwink

I have never heard such pedantic, although accurate crap. As a trade qualified & practising electrician in both electrical distribution/transmission and mining for 46 years as well as holding an Associate Diploma of Electrical Engineering I'm actually ashamed that others with presumably an electrical background could so ridicule the author of a post that to me, whilst technically inaccurate, was quite understandable to the average person. LW was merely trying to help and if the way this topic has gone turns out to be indicative I'll be moving elsewhere.

Hi Jack

Thanks for the correction 

A senior moment under pressurefrustrated.gif

Yes ,that means you too are being pedantic handshake.gif

I think in the eyes of some, we pedants now number about 5or 6 wink.gif

Hi

Hubby and I debating ? over whether 12 volt is necessary .We will be free camping where possible

Thanks

Forget to add we will have a generator as well

 Hi Chris

Sorry for your question being buried

Now to your question

YES if you expect to do a lot of free camping ,A good 12v set up is essential.

But I would suggest it be based on 12v equipment & solar

Generator are useful in an emergency but are expensive to run as a main source & you may have problem in some areas such as National parks where they are often banned & with neighbours in other areas'

You should use gas for ALL heating & cooking

Forget about trying to run anything like that from your solar & batteries unless you spend BIG money

I would also suggest you forget about inverters ,they have inbuilt inefficiencies & are potentially dangerous unless the 240v side is permanently wired into the van system IN THE CORRECT MANNER

What you need to do is sit down & list :-

[1]what appliances you wish to use

[2]how long per day you expect to use each of them

[3]the WATTAGE rating of each

[4]Multiple the hours of daily use of each by IT'S Wattage rating

 

Add up all in [4]

That will give you your expected DAILY requirement of ENERGY[Watt Hrs]

Then determine the period that you may wish to free camp without other means of recharging the batterries

From that the solar panel requirements can be caculated

You may be able to use the geny for emergency recharging subject to location but you would need to have a large capacity charger for fast charging [NOT THE 12V output of the generator]

If you do frequent driving while free camping ,your vehicle alternator can also assist

"Power Stream " can help in that area

Lots of points are required to be considered  before you will have a set up that will meet all your needs

Others include:-

  importance of cost recovery .

What are you prepared to spend

 actual annual use

how long you may wish to follow the lifestyle with the same van

Then specific items of eqipment need to be considered including the advantages & disadvantages of each

The most contraversial is the FRIDGE type[absorption3way ,or compressor type]

Compressor type involves considerably more investment in solar & battery capacity for long term free camping

Peter

We are here to help

 

Some here are qualified to answer any further questions,so do not hesitate to post with more questions


Hopefully ALL the replies, to YOU, will be based on well known & correct terminology to avoid ANY confusion

Hi Peter
Yes I did see your last post and it was very informative , thank you . We now have some idea of what we need re power supply .
One step at a time and its easy peasy
Cheers

well I did put into search 12 volt...most of the above has put me off looking, far to complicated for me.

Maybe the Battery World bloke might be better.

......There was a page 2, thanks for that looks easier to understand.......

Hi

 The Battery World bloke would probably be the LAST one to take advise from no

 

Most are just salesman with a speil
