Thanks Paul = that's so great to hear! :-)

Cheers 😀👍🏻

Hi Adriaan, thanks for your very kind words. Hope you enjoy the movie! :-)

come to see the comment when I heard that 😂 just some small mistakes, still a great video, many thanks

Hi John, thanks for taking the time to comment and also the kind words. You are correct - I've no idea why I got this part wrong - I was using a wiring diagram I found on the Internet, but when I searched again just now, the only diagrams I find are indeed ones where a neutral line is used. I'll add a correction to the video and also the description - thanks for highlighting!

@@GaryDoesSolar No Problem keep up the good work

Yes, I picked up on that one as well; having 415 volts in the house could be, well shocking. Having said that, I put 3 phase in 30 years ago, mainly for the machines in the home workshop. Now have the advantage of being able to fit a 3ph car charger.

You're most welcome, Ian - glad to have helped out! :-)

Many thanks, Andy! Working on the next one now... :-)

Thanks Stephen! :-) Really glad you liked it!

My pleasure! Glad that you're getting something out of them. They're a lot of work, but I'm enjoying the process. I've got more than 30 video topics in the pipeline, but I'll add this one to the list. I select a topic for the next video from that list, depending on what I think will be the most popular one at the time...

OMG! I can’t believe I got that calculation wrong! Thanks for pointing out 👍🏻 I should have used 8 panels per string 🤣

Thanks for your super quick answer.

Agreed

You're very welcome :-) Ah yeah, if you were on Bulb, then by default you have already become an Octopus customer, which is fair I guess?

Hi Andrew, I guess humankind can (and will) argue about that for years. The pragmatic point is that so long as the direction of current in any electrical diagram is stated (as I did) then that holds for that diagram.

@@GaryDoesSolar There's no argument. It's GCSE level physics.

... as we understand things *today*. Given our understanding of direction of current has changed a few times over the last 100 years, I would not bet my life that it will not change again. Irrespective, I refer you to the last sentence of my previous response.

​​​​@@GaryDoesSolare never consider electron flow except when analysing the behaviour internally of semiconductor devices, or when dealing with valves or fluorescent tubes and cathode ray tubes or when teaching about how capacitors work. It is not relevant to any discussion outside of these devices. It is only relevant for understanding how these devices work but it is not required to use the device and make it work in a circuit

haha - love it!!! :-)

Hi Eric, I knew whatever I said about the flow of current in the video, I was in for a debate. When I was studying, I was taught that conventional current was wrong and that current flowed with electrons from -ve to +ve. It seems today that conventional current is indeed correct (at least according to some sources) so I really don't have a clue. And whatever is correct, I'm sure in the future we'll come up with a different understanding! So, I decided to work on the basis that if I clearly indicated the direction of current in my video, we could at least all work to that :-)

​​​@@GaryDoesSolarI will explain it. I am an Electronics engineer. Electricity flows as electrons from negative to positive. Somebody many years ago thought it flew from +ve to -ve and got it wrong. So we are stuck with that convention. However, you never need to worry about current flow as electrons unless you are involved in designing semiconductor devices such as diodes, transistors. You don't even need to worry about it if you are designing integrated circuits. Thermionic valves you may have to worry about it. Other than that, you will never need to worry about which direction the electrons are flowing. Considering current flow as +ve to -ve does not cause any issues 99% of the time. The problem comes when poorly trained and poorly educated amateurs try to show off that they understand electricity by talking about electron flow because they think it makes them look clever, when in fact all it does is cause confusion which is entirely unnecessary. My advice is, forget electron flow unless you really need to deal with it as in say the analysis of operation of a semiconductor device. Trust me, I have done a lot of analysis of electrical and electronic circuits and you can completely forget about electron flow. The reality is, when doing analysis you may not know which direction the current is flowing in the circuit, so you ascribe letters to the currents, draw arrows on the circuit diagram and when you have completed the analysis any negative figures you derive simply indicate the direction is flowing in the opposite direction to the arrow you marked on the circuit diagram. So it in practice, whether you are considering conventional flow or electron flow the result of the analysis is going to be the same, just that in one scenario you will end up with opposite polarity numbers and it is the polarity + or - for the current which indicate its direction. The key thing is, we all standardise on the same current convention so we can communicate effectively. And that standard is conventional current flow. It doesn't cause any issues. When I find people talking about electron flow, which happens occasionally, and are trying to push that as the correct way to describe current flow, it nearly always sets the alarm bells ringing in my head because it is nearly always people that are not educated to degree level in electrical or electronic engineering.

Fair comment, Claire!

@@GaryDoesSolar nonetheless a good made video. I watched all your videos and I learned a lot. Thank you 🙏🏻

Hi Claire - thanks for the kind words. I studied electrical and electronic engineering, so I really should have been more diligent! 👍 I wouldn't trust myself with any kind of high voltage system today! 🤣

Hi Stephen, in actual fact my last two videos were done in preparation for a future video on that very topic - likely the video after next :-)

@@GaryDoesSolar very good. Did I mention that the EV batteries are huge and free with the vehicle, Hahaha.

@@stephenbrickwood1602 And one day, I hope to be able to *afford* an EV 🙂🙂🙂 You're totally right though!

@@GaryDoesSolar Saul Griffith's book, The big switch, is full of facts. He is way ahead of me in his thinking about the dimensions of the change to a renewable world, from an Australian perspective. He has advised the USA president teams, he is an engineer. Australia's 20million vehicles, if EV, would mean upto 2,000gWh of stored electricity daily. DISPATCHABLE energy. And if the big EV learns the little home robot vacuum 'skills' of plugging in to a power supply then a vast amount of stored energy is available. 3 or 5 days minimum. Just saying. He wants Australia to do it first and so lead the world. South Australia is on the way.

Yeah, this was an error. I originally had 8 panels in the diagram but reduced to 6 and didn't change the calculation. There's already a correction label in the video, and it's a pinned comment.
