Re: Tesla to announce new revolutionary product Apr 30

I don't think folks are criticizing Davydd's RV, it is a very nice rig. But, by the same logic, why does someone else choosing lower cost and simplicity make them a Luddite? I suppose tent campers...

Definitely a different pattern than us. We spent 3 days without power in wind cave park without moving, and then went to Custer, where we had power, and in 14 days, we drove the...

Re: Tesla to announce new revolutionary product Apr 30

You are very similar to what we are, everything 12v if possible. For us it is air conditioning, micro, and hair dryer. Don't like coffee :shock: Our inverter is also always off. Even 2 amps will...

Re: Tesla to announce new revolutionary product Apr 30

yep-it is all a balance.

The reality is that having 600ah usable and using 200 a day and charging at 200 amps driving isn't all the different from having 100ah usable and using 33 a day and...

Re: Tesla to announce new revolutionary product Apr 30

Mike makes a good point about the terminology. I generally prefer the term offgrid to simply say no electric power available from outside the van. It would cover all the examples Mike stated. ...

Re: Tesla to announce new revolutionary product Apr 30

OK, so I make a comment that folks are talking about propane giving equivalent boondocking capability, and you go off on line that you have a lot of electric power to boondock compared to other...

Re: Tesla to announce new revolutionary product Apr 30

I think the point folks were making is that propane can give you equivalent off grid capabilities compared to huge amounts of battery power. (you asked when someone like Winnebago would do it, and it...

Re: Tesla to announce new revolutionary product Apr 30

Mlts22-has anyone done a comparison of propane use between an absorption frig on propane, and a compressor frig being run on power from the Truma propane fuel cell. If equal, you could have the...

Re: Tesla to announce new revolutionary product Apr 30

You must be referring to this statement



I totally agree with Wincrasher about the propane, and many folks with older units have added a couple batteries, some solar, and a big alternator. ...

Old engineers line, but very true, and it applies to all of this we are discussing, I think. If you just do what has been done or...

Re: Tesla to announce new revolutionary product Apr 30

I agree with Avanti- Tesla is extremely technically competent, and also very, very, safety minded, but they still had to address some fires do to unforeseen, odd, circumstances.

It is not usually...

Re: Tesla to announce new revolutionary product Apr 30

When you talk about warranties, you can't really compare a home system, be it off peak storage or solar storage, to an RV setup. The home system is going to get 365 cycles per year, plus one every 4...

Re: Tesla to announce new revolutionary product Apr 30

An inverter is not included with the PowerWall, it costs an additional $2K or so.[/quote]

That would run up the cost a bit :shock: Does it include the battery charger?

Re: Tesla to announce new revolutionary product Apr 30

Interesting article here:

They give raw material costs, what Tesla pays Panasonic now, and the tipping point of cost vs energy...

Re: Tesla to announce new revolutionary product Apr 30

If I did the calculations right, the Tesla 10K system comes in at about $4.70 per amp hour of 12.5 volt power. Mojovan bought a 900ah setup recently for about $5.70 per ah, so the Tesla is a good...

I would bet if Tesla built an RV battery pack it would have all the right charging, temp control, safety stuff, right on the money, but not be...

Re: Tesla to announce new revolutionary product Apr 30

Yeah, if power is cheap and capacity is not an issue, the storage systems are a non-issue.

As a point of reference, at the last place I worked before retiring we would have a power spike of about...

Re: Tesla to announce new revolutionary product Apr 30

Re: Tesla to announce new revolutionary product Apr 30

This may be an off peak system primarily, and not necessarily solar. A lot of places have such good off peak rates, that you can afford to store the off peak power to use later, and still come out...

Re: Tesla to announce new revolutionary product Apr 30

They have been working on aluminum based batteries for a long time, as the article states. It will be interesting to see how well it develops. The low voltage is probably not a huge issue as you...
