Waeco can size Inverter,

Hi Wayne,
Thanks for that!

I'm looking at charging camera batteries as well as running as weird as it may sound a CTek battery charger (6 Volt 0.8 Amp version).

Sounds like from your experience it will do what I want.

I was a little scepticle about it running switch mode power supplies but I'd guess your camera charger will be one.

Sounds like your new RV Troopy is serving you well!

Thanks agan,
Geoff

Hi Ian,
Forgot about that one!

How's life treating you?

Geoff

Good Geoff
Hey your vehicle picks dont look like the one I last seen you in .

Rods County Camping will be there tomorrow demo ing DC Wheel nut removers and step down nut removers for trucks and Ive got to drop off some bits for him.

Also with him will be Jason Wilson and his brother Paul pushing Amsol synthetic oils and the new Sequent 11 Diesel Gas System Designed in the Hunter Valley by Hunter Gas Technolgies and appears to be superior to every thing else available.

Regards
Ian.

Ian, ya silly bugger you missed by one reply.

Sounds good, do you want to sell me one of your small Sterling Inverters?

I'll give you a ring on Monday to discuss.

I'm also doing a project at work that will probably interest you, can't discuss it on an open forum.

I've still got the Troopy. Same one as you saw me in last time.

Don't forget your always welcome for a cuppa.

Geoff

Yep Thats me .Silly B.
Ill be back down probably wednesday and I can call by if you like and Ill make it cuppa time.

You might stick one on the oscilliscope and see what it looks like.
I wonder if it will be as fuzzy as that Inverter gen that you tested you know the one that would not run a thurister controlled washing machine but I believe that has now been corrected.

Be in Touch
Regards
Ian

I hope they dont moderate you for bad spelling I meant Thyrister not Thurister.
Ian

Your spelling is probably safe, I'm in strife for calling a silly bugger a silly bugger though.

Yep, no problems on the oscilloscope, we'll do that on Wednesday too.

Nobody in head office has noticed it's missing so it's available anytime you need the output of something checked.

Throw in one of your Strong Box adjustable battery boxes too, I need a second one. For a silly bugger you have good gear!

"I wonder if it will be as fuzzy as that Inverter gen that you tested you know the one that would not run a thurister controlled washing machine but I believe that has now been corrected."

We'll find out on Wednesday won't we! I'll toss the transformer we used for the last tests into the wagon in the morning.

See you Wednesday,

Geoff

You can have mine for $35 including postage Its been used twice then I bought a 12v converter for the Laptop

Due to the complexity of sine wave versus modified sine the sine wave inverters have a higher useage quiescent power need thean the modified sine.
Maybe hardly noticeable in small units but becomes more noticeable as the capacity increases.

Ian time you went to university or did some studying to update your knowledge. On the other hand to bring that up here in the context of the inverters being discussed is bordering from ludicrous to ridiculous and useless.
Overall and in the majority of situations a sine wave inverter will have a lower power requirement for the equipment users here would be using with the inverters. Leave the wanky unecessary stuff for the technical forums where it may be relevent.

Thank you Paul for your post I did not realise that you knew me so well but to enrol to study further may well mean that I would displace someone younger that may really need to upgrade their knowledge to get a better foothold in life today.

If as you say I have to update my knowledge why should you state that the contents of my post should be placed in technical forums where it may be relevant (not relevent).

I try to keep up with technological changes today and that is difficult and the information was gleaned by me from a qualified engineer that designs for a major US OEM supplier of electronics including inverters.

He stated and wrote words like the following:

People think that the Quasi Sine Wave (Square Wave .Modified Sine Wave) was dead and that Pure Sine Wave would rule the world but Quasi Wave Inverters have continued to outgrow sales of pure sine wave proving that there is a lot of life left in this technology and the reason for this is a that a lot of equipment such as mobile phones ,TVs, drill chargers and all sorts of equipment that used to be a problem with Quasi sine are no longer a problem as this equipment now uses switchmode power supplies which will work fine on quasi sine wave form inverters.

We have always found the quasi sine inverters to be smaller, lower cost, better performance, more efficient and more reliable than sine wave.

With new technology and features new quasi sine can reduce running costs with a lower quiescent power need than pure sine.

There is the odd appliance such as a washing machine and some breadmakers where quasi sine wave inverters simply do not work but all in all we find this technology is adequate for the general requirements in boats and vehicles.

As much as this is a personal opinion of this engineer it is still one that is at the coalface of change and with direct involvement in the industry.

My post was of general information that I considered appropriate to inverters and your statement of “ludicrous, to ridiculous and useless” should be responded to with an explanation for the person or persons that may think it holds some value to them and its up to the individual to apply it or not apply it to their own use and your input would have had better value for the readers of the forum if you due to your now indicated superior knowledge ask further why the statement was made rather than show your condemnation in a way that does nothing for the general readers and perhaps turns them away from further input.

Ian

Perhaps the posting of my testamur, my industry experience, my current industry position, current relevant power generation and current power reticulation project experience as well as several TAFE qualifications would add some credence to this discussion?

Paul, I asked a specific question on a specific device.

I did get some great alternative information from some really genuine people, you included. This really supports the power of ExploreOz.

As to Ian's very relevant point, he is 100% correct. The quiescent current of the Pure Sine Wave inverter (another oxymoron if you introduce an oscilloscope) is greater than the quiescent current of the Modified Sine Wave come Modified Square Wave inverter. (The exact terminology is open to interpretation)

Is this relevant in my question? Not really.

Is it relevant if I was chasing a 2kw inverter? Very definitely.

I suspect the recent retaking of the Forum by the owners and moderators is in no small way driven by these personal attacks without substance.

Why do these electrical type threads always attract this kind of vitriol?

Sadly the vitriol is of the "guerilla warfare" variety, dive in, fire a round and run for cover without any substantial backup.

I'm over it, I'm sick of answering questions in a field where I have over 30 years experience and the formal qualifications to back it up only to have someone who's skills and experience are based on internet guerilla warfare and/or Google dive in and attempt to drag the post into the gutter.

I can actually understand how Mike Harding feels on this subject right now.
