Further, the numerous IPs for all the failed researches have similarities to a successful prototype and will create lots of court cases over its IPs rights. The world need to accept and prepare an agreement for the safety exposure of a real working prototype and not challenging its rights with similarities in designs and theories etc. The very first successful working prototype should get the IPs. Better still, a European Noble Prices for it.

Note that in the past thousands of IPs have been registered with failed researches. These are very bad intentions to claim over the IPs rights , challenging with legal procedures. Agreement should be made, IPs rights should be given to the first successful working prototype in the world.

What is chocking?

As i stated in the beginning of my video, there is nothing wrong with a 12 volt system. The problem i had with his video, was the mis-truths he associated with the 24 volt systems. Things like needing special boost converters, things are harder to get in 24 volt than they are in 12 volt, and that a victron system to do the same job in 24 volt, would cost 40k. These are the things i wanted to address in the video. And if you have seen my next video, i put together a full Victron system cheaper that the average quality Itechworld kits.

When driving a DC load such as a light, radio, even brushed DC motors, there is no ripple as any inductive DC loads will have smoothing capacitors in parallel with that load, and so there are no eddy currents. I have been working with DC for 30+ years, so I think I have a good hold on it. So no, I am not wrong in my statement, but thanks anyway.

Well that's a bit of bad sportsmanship. Unfortunately some people are only interested in what they have to say, and not interested in facts, or having people correct their mistakes. So, they just silence the critics.

you are technically right however I think his video was not meant to stop 24 V but to let people know that if they have a 12 V system there’s no need to change it. This I think was the purpose of the video he made. it would depend on whether you need to upgrade and which way is the cheapest. As going from a 12 V to a 24 V would mean a complete redo and very costly.

My company has a fully qualified sparky, but he is also a fully qualified off grid systems sparky. I agree, some sparkies know the in's and out's of off grid systems.

As far as that video go's, I would have to agree.

1. Electricians do very little work on ELV DC, when compared to someone like myself. 2. You do not change the cable size in a caravan when going from 12 to 24 volts, so my description of losses in the cable is exactly correct. You go by the current flowing through them, and the resistance of that cable to calculate ohmic losses, not voltage differences. Only Keelan mentioned changing to a smaller cable size, not me. 3. Keelan said doubling the voltage means halving the work done by the batteries, which it does not. The same amount of power from both battery banks is being delivered to the primary side of the inverter. In my example of 50 amps, both the paralleled batteries have 25amps flowing through them. In the 25amp example, both the series connected batteries have 25 amps flowing through them. In both cases, the batteries are doing the exact same amount of work. 4. Quote ( In your first example you used 5V and 50A in your calculations, In your second example you used 2.5V and 25A, What gives?) A classic example of what I am talking about. You too claim to be an electrician guru, and yet fail to understand something as simple as ohms law, so I will explain it to you. 12v system-If you have 50 amps flowing through cables to a load, and the total resistance value in those cables is .1 ohms, then the voltage drop across the cable is 5v. 24v system- If you have double the voltage, then you have half the current flowing through the same cables to deliver the same power to the load. So, you will have 25A through .1 ohm of resistance, which give you a V/drop of 2.5v across the cables. So, that's what gives. 5. Not as robust as a good step up transformer using a H bridge. 6. Being an ex trucky, I can tell you that 24v items are just as available as 12v items in the outback. 7. Which is exactly what I said in my video, so have no idea what you are on about there. There is no fiction in my video. It is only you not understanding how things work. What I see from your comments, is that you seem to be another that has all these papers, and yet cannot work out what the 5v and 2.5v difference means--you got all confused. So, what fiction did I present as facts? please specify.

@@69Atho 1. Electricians do work on ELV systems and are licensed to do so. PLC's, Home Automation, Control Wiring are typical examples where fully qualified and "Trained" electricians work on ELV systems, but are not limited to just them. 2. It would be insensible for caravan manufacturers to put larger cables than what would be required as it affects their bottom line $, and it's ability to compete price wise with others caravan manufacturers, not to mention any additional weight heavier cables would have. If a caravan manufacturer could save $1 per caravan, and sold 1 million caravans, it would affect it's bottom line by $1million; That's how research, design, development and manufacturing operates. 3. I don't recall Keelan saying that doubling the voltage halves the work done, however I do recall him saying that it draws half the current, for the same amount of work done, ie, the same power consumption; that's just basic ohms law. 4. Ok so I misread what you had on the computer screen, it's a bit hard to see. Yes Lowering the current draw from 50A to 25A will indeed decrease the voltage drop and consequently power loss along the cable length due to I squared x R. 5. Whether you used transformers with H bridges or clippers and clampers, switch mode power supplies are still the way to go in my opinion. You do know they no longer varnish transformers any more to which makes them more robust right?. 6. There are far more 12v items than 24V items on the market at the moment. That may change if 24V became more mainstream down the track. 7. You need to separate facts or what are known to be facts from your opinions. Throughout the video or at least from what I've seen of it, you've mixed facts with your opinions and presented them as facts. You need to separate the two or loose credibility IMHO.

​@@magicalvortex Seriously, dude, keelan and yourself are a total embarrassment to the electrical trades. I've been a sparky for nearly 30years and I cringed when I saw Keelan's video, he made an absolute mess of it, just so many things wrong, and you want to back him up? FFS, call yourself an A grade electrician, and you can't even understand this video.😂

@@magicalvortex Once again, what is it I presented as an opinion? Keelan said in his video that 30vdc was considered safe, when in fact, the Australian and New Zealand electrical safety commission clearly states that any confident person can instal ripple free DC systems up to 120VDC- that is what they deem safe. AS/NZS 3000:2018. Please go watch Keelans video again, from 7:40, where he clearly states that the 12 volt inverter is doing twice the work of the 24 volt inverter, which is not true. They are both doing the same amount of work, where they are both consuming 1992 watts using his numbers- electrical work done is in watts, not amps as Kellan states. He then claims that you need more components in a 24 volt system, which you don't. He then go's on about needing blocking diodes in series with a 12 to 24 volt boost converter to stop feedback to the car, which you don't, as you just use an off the shelf DC/DC charger to suit the job, as I showed. Keelan also states that he has never messed around with 24 volt systems, so how exactly is he qualified to compare the two? Watch from 15:23 on his video. So I ask you, who is not presenting facts? And what opinions have I presented as fact? If you are out in the outback, and need a new inverter, charge controller, or DC/DC charger etc, I'm pretty sure that the local servo or store is not going to have any of them, and you will be getting one shipped regardless, in which case, both 12 and 24 volt stuff will take the same time to get to you. I have no problem with people posting comments, but I ask that you back it up with proof, and show what I presented as an opinion that is not fact. It is a fact that I can jump on line, and order anything in 24v that I could in 12v- I showed this live. Keelans video is opinions not based around facts, and that is because Itechworld sponsor him, and so he has a bias toward 12 volt systems.

@@69Atho I've watched Keelans video again from 7:40 and yes he does say it does less work, But I know what he means is that it produces less heat (24V), he just doesn't express himself properly. Less heat = less losses internally and so forth. It's just nick picking. You've just stated that both the 12v and 24v inverters consume 1992 watts, which is incorrect, but I know what you mean or trying to put forward. The load would consume 1992 watts that the inverter would put out, the inverter itself would consume measurably less. Again just watched from 15.23, and yes he does loose himself a little, he's clearly referring to the potential of internal short circuits in equipment and that itself providing 24V to 12V appliances, again, doesn't explain himself properly, There is potential for failure, but there should be protection measures in place particularly for expensive equipment/appliances. It is true that Kleelan presents facts mixed with opinions, but you both do it. His presenting his opinions based on his knowledge of electrical systems as a qualified electrician, and his personnel experience and travels of the outback, and there's nothing wrong with that. Your looking to tare him down with your knowledge of ELV systems (I don't know what quals you have), and opinions like "Electricians don't generally work on ELV systems". Electronics is becoming more mainstream in the electrical field to such an extent that now you have electricians that also specialise in data and communication amongst other things.

6 months, over 300 prints, and not a single problem-yet

Odd, my K1 Max has fewer vfas than my A1

Thanks for the info.

To add, at a power factor of 1, 3000VA is 3000 watts. I have found that most inverters that quote 3000 watts, are quoted at a power factor of 1.
