Keegan, Finally after many years of watching UA-cam videos on the subject it’s very rewarding to finally come across somebody that actually knows what he’s talking about, as I come from the same background. Keegan totally ignore the knocker’s as most of them could not even know what ohms law was and would have no idea how to use it. Keegan keep up the good work. G..
Thanks Graham! Appreciate that mate! Haha there’s always going to be ney sayers.. most of them want to sell you something that I’m telling people they don’t necessarily need! 😂 cheers mate!
I don’t watch a lot of UA-cam but I have been living off grid for 6 years and this guy knows what he’s talking about it’s probably because he’s not wearing shoes.
Thanks Keelan I'm 65 female and just starting out on the road. Your knowledge is easy to digest. Learn something everyday. Safe, travels to you and your family.
Main takeaways are at 16:33 - Use appropriately thick cable - Use MPPT controller if you have a large solar panel bank (otherwise PWM controller fine for smaller panels) and keep controller as close to battery as possible - Keep your solar panels clean
You're an absolute legend mate I'm stuck at a camp-site with no power to my battery! I just simply put my regular to the battery side of the cable from the solar panel and I'm now getting huge amps and fridge is working again! Thankyou! What a difference
There are squillions of off grid videos, but this one is, in my view, one of the best I have seen. Explaining 12V systems is a blind spot in the other videos. Well done.👍
I'm up on most things electrical, and as a 4WD and Van owner I commend you on your video explaining this to people who don't understand. I have seen some shocking installations over the years and what is surprising is that a lot of Caravan manufacturers are using the wrong size cable. Remember most Caravan manufacturers are like used car salesmen and will cut every corner they can. They don't even balance the wheels on your van from new.
thanks Andrew! thanks for the kind comment mate! glad you enjoyed it and I explained it semi well. its all about cost saving for most manufactures thats right! We are very happy Urban Caravans are always trying to improve an already good product and the R & D testing we do in the field is put into practice so the next customer gets an even better van than ours!! cheers mate
The very same 12v rules applies when you build an overland camper van too. Roof full of solar and a blanket and fat flex for the win. Especially true here in UK where the sun only really shines for 3 hours at the height of summer on august 12th, if we have a lucky day. Your island is a lot bigger than our island and seems to have eternal sunshine. Lovin' your channel.
Have learnt more in your last two videos about solar, setting it , how it works and what to use than the research and watching other vids over past two months 😂. Again thanks mate !! When you finish being a sparky you need to teach it to people ! Doing a bloody awesome job 🙏☝️🍺
Mate I wish I had have watched this a few days ago. Great video!!! Just spent 3 days double checking all the wiring on my camper as it would not charge from my car. Itech 40amp dcdc charger in the camper. Turned out the auto elect put the smallest wires possible from my battery to the back of the car. All I did was use the right size wire and all good. Crazy difference
The easiest way to explain the difference between a PWM and an MPPT controller is that the PWM controller is pretty much limited to the voltage it sees from the panel, if the panel is proving a high voltage this type of regulator will simply clip it, the battery will charge but not as efficiently. These can work well in sunny conditions, in shady conditions these can limit charge to a point that they are pretty much ineffective. A MPPT charger on the other hand ( think ohms law ) can convert the higher input voltages from the solar panel, to the 14.4v / 13.8v ( charge profile specific ) and increase the amps, rather than just clipping it. It provides a better charge cause it makes use of excess voltage by converting into amps. This is why an MPPT charge controller will provide better performance in shady conditions. Especially when mated to a higher voltage panel. Keep up the good work! Keep living the dream!
Very true. I switched the pwm controller on my 200w glass portable panel over to a mppt. The difference was substantial and the reduced battery charging time quite notable.
Thanks Keelan !! Your videos are way more helpful at putting an awesome solar generator into my pop up camper !! You are very smart about this solar stuff and love your videos on very knowledgeable about Solar power!! Keep making these videos!! And explaining it so well too !!
I really appreciate these videos where you try to simplify electrical systems for those of us who know absolutely nothing about electricity. I’m so confused, but your videos help! Voltage, watts, current, amps, DC, Inverters, regulators, resistance, 12 volt… does my head in lol 🤦🏻♀️😂
Glad to see you taken your own time to explain this to users. Its so common that as you state you get suggested the correct amp cable but incorrect gauge of cable you need to use on distance and draw. Thanks great video mate cheers...
Gday Sarah and Keegan. That I think is the best explanation of how to get the most out of a 12 volt system that I’ve heard. I’d never heard or considered the voltage drop from the regulator on solar panels. Thanks for the tips 👍🏻
Thankyou! Thankyou,! Thankyou!!! I have my car booked in this week to have a brake controller and Anderson Plug setup fitted, thanks to your video I will be asking them to use 35mm cable instead of the 6mm cable I can almost guarantee they would have installed. Awesome and informative video, thanks
Lots of great info about wires and DC charging. As an electrician in the US I try and explain wire size like a garden hose. Larger diameter hose will carry more water. A thinner hose must have higher pressure to try and flow the same ammount of water. Of course even higher pressure can only do so much (resistance) will still not allow as much flow. I love the term "Sparky" I try my best not to spark myself when working...
I've just discovered your channel and wow! Super impressed with your passion, energy and sincere desire to debunk myths and help people, legend. Really enjoy your channel.
M8 just came across your video today, and how easily you have made it for me to understand this, I take my hat off to you! How you explain it all is why I am now going to subscribe to your channel. It's my pleasure to see your videos and keep them coming. On ya m8, cheers! Great set-up you've got as well ! Enjoy the great outdoors.
Great vid mate, I love learning about this. The difference the thicker cable makes is insane and something I’ll be taking into account on our next build.
@@SarahandKeelanTravels that's one wire of a 2-wire system - you don't mention earth returns at all & they corrode though usually slowly enough you don't notice till a big fault develops. Earth returns require an absolute minimum of the same thickness cable & they need to be dismantled & cleaned up regularly. Earths are frequently overlooked.
Thanks Keelan - I know very little about this stuff - I'm one of the dangerous ones - so I learnt a lot - had no idea the thicker cables made such a difference. Excellent video. Liked the chilled presentation style too and the upfront acknowledgement of the iTechworld affiliation.
Thanks legend!! Glad you got something out of it! We are just trying to help as many as we can! Arm you with the right info to make your system better!
Thats why I like my Kickass cabling kit for my Kickass battery and box.Itech DCDC charger not badly priced.might go for that.Sorry i missed catching you at the Sydney show.Saw you there but wifey rushed me through.
Watched two of your vids and learned more than watching dozens of other vids on the topic, with better and more practical explanations as well. Thanks!
One thing a lot of people don’t realise regarding the length of the cable is that with DC the run is both ways, so this has to be allowed for in your calculation regarding cable size
@@donherley1811 correct, which in short runs of 1 or 2 meters is no big deal, but if you have the appliance 5 meters away it is a run length of 10 meters which In most cases will require going up a wire size to prevent voltage drop.
I use a DC amp clamp and a thermal image camera for my installation. I use a DC-DC converter to charge and compensate for voltage drop, you need to current limit the charge. Using a 62V solar panel setup (560watt) with a MPPT, works great! Hello from the States!
Way to go!! Opening right up with V!! P=IE, awesome!! I went through 6 inverters before I finally found one that actually held 119VAC (USA) regardless of load or input voltage. I also see tubers building battery banks with bolted in fuses, and no disconnect...lol. Thanks for thoroughly demonstrating how important cabling is. I say the bigger the better! It hurts bad initially, but there's nothing like cool cabling, literally!
Nicely done. Good demo to show the effect of wire resistance on voltage drop. For the math, I just did a little calculation for 50 Amps across 20 meters of copper wire. For 6mm diameter wire, voltage drop is 3.3V, power loss is 165W. For 16mm wire, voltage drop (V = IR) is 1.21V, power loss (I^2R) is 60W. So, if you're running high current on a long wire run, and you want it to be efficient, fat is where it's at. Fat wire, that is.
Thanks great vid. I know a bit late to the game but thanks for coming to NZ loved that series. As you said the costs even living here half of the time the locals can’t afford some of the activities. Come back and see the north island.
Great explanation video put in a simple language that no doubt helps many people. One of your best. Keep up the good work. Love most of your videos!!!!!!!
Great video Keelan! I'd add that most wire manufacturers specify Ohms/foot. From that you can calculate total resistance for a run of cable and if you know source voltage and load resistance, you can calculate total current draw and voltage drop to the load.
Well explained...and of course voltage drop creates a higher current demand, further loading the cable. Also the AWG current loads on cables are rated at 28 degrees centigrade
Finally, it makes sense to me. Thank you. I am someone that needs to know the, "Why", behind how things work. If I want to learn more about the technical aspects behind electricity, is there an educational book or class program online that completely breaks it down with examples and an explanation of scientific terms, I could take as a complete novice that you would recommend?
thanks legend glad you understand it! im an electrician so a lot of the principles are transferable between 12v DC and 240VAC. I also have done a fair bit of work with DC in controls so understand it well! you could do your CERT 3 at tafe which takes around 4 years and you'll be a qualified electrician or Auto sparky
Hi guys thanks for the great explanation. I have just purchased a complete Itech 3 battery system for my truck. And can't wait to start my canopy set up. Cheers.
Thanks Keelan, hubby really appreciated your top tips, especially the one about the regulator closer to the battery. I did give him a look 😲 when you said to clean the panels!!!! Top work and we love our itech world gear 👍
Thanks legends! Glad you got something out of it!! I would say the tips were in order from most important to least! Cleaning your panels you’ll get the most out of though for sure!! We do too! Such great value for money too
Awesome Vid Keenan, I have just finished my sons Canopy fitout with 12volt system and explained the importance of heavy cable to him! I did mine 3 years back and it works a treat. Thanks for sharing, we love your channel, cheers Pete
Thank you for this. I have been watching RV solar and other solar videos for a while, I got more information about how to 'set up' a system than I have in all the hours I have spent trying to learn about the systems.
Thanks for taking the time to explain that in detail mate, that was excellent and confirmed what I believed I was doing correctly, was actually correct 😂 Good solid reminder to keep an eye on the panels and give them a cleanup regularly too. 🤙
Awsome video mate. This is a massive issue that van companys arnt addressing when they sell people these big 12volts systems for their vans like what happened to me. Cheers for the info. Very well explained aswell. 👍👍
Thanks mate!!! Since we have been working and R & D testing vans at urban we have now made 16mm standard on drawbars on vans! 99% of all other manufacturers still use 6-8mm
Great vid and tips here Keelan, it was good to see the difference the wire guage made in real practice. I use a lot of the cheaper Chinese type Anderson plugs & find some to be very dodgy, so proper connectors is probably a good tip too,as a suspect connector can give you variable throughputs as they move/ vibrate in transit, so when testing can appear to be ok,but when moving can greatly influence what can be drawn at the load end, meaning a fridge maybe working ok when you leave, but in transit it can be switching on & off & taking time to restart each time, so appear the fridge is not working correctly when in fact it is, voltage drop as you say, from thin wires or bad connections, Cheeers
Thanks mate! Glad you enjoyed it!! 100% sometimes you get exactly what you pay for. I personally think when it comes to solar there isn’t much difference between a panel that’s 1000$ and a100$ panel.. cheers Evan
@@SarahandKeelanTravels true that, but I also believe the flexible type are generally less reliable for various reasons, they seem to have a high failure/shorter life rate from what I can gather.
Great video Keelan. The only thing I didn't understand (as a person who just bought his first 4X4 and a trailer) - did you say you ran 35mm cables for your system? That's one heck of a wire.
Thanks Keelan, great video, best I have seen actually. What size Anderson are you using? PP180 that can take up to 70mm2 cable, as the smaller PP120 can only take up to 10mm2.
@@SarahandKeelanTravels No worries mate it really was top notch, Bewdy I will only use PP180’s is from now on in for 12 and 24 volt run’s especially if DC to DC converters as well - really good points you made - Cheers and fun travels!
Excellent vid mate. Subscribed. Great hearing people who know what they’re talking about talk about stuff. Do you see much of a drop over different 50A Andersen plugs?
Thanks legend!! Welcome to the channel!! Are you talking about smaller Anderson plugs?? Generally speaking the smaller surface area on the connection the more resistance and more loses such as heat ect, the bigger the surface area and the tighter the connection the less resistance, less loss and therefore less volt drop!!
Thank you Keelan. Greatly appreciate your input. Just looking to purchase our first van and want to save where we can but also make sure it's quality and done right the first time. We've watched so many videos on what you get and how to do it yourself. Heading of to the Sunshine Caravan show to check some of these vans out. Soooo looking forward to hitting the road one day.
Excellent presentation! Cable size is #1 cause of insufficient charging/failure I've come across. The 2nd are connections. It's stunning how I've seen some connected. 100% copper is the best cable and lugs to employ. Buy once, cry once. Again, you really nailed it. Well done. Now one about those cigarette lighter sockets...dump those things....maybe your next video...
Hi Keelan spot on mate have changed my to cable throughout vehicle and van and the amps are all the go by the way mine is itechworld gear aswell so far so good
Nice one Keelan. Happy you mentioned regulator as close to battery as possible, proved I was right in an argument where mate reckoned since manufacturer fixed it onto back of panel not on end of cable that was where it “had” to be 👍👍
Some ways to help teach these principles might have focused on cable resistance per metre for various thickness of cable. Then show the voltage drop across the cable run. Then the DC-DC converter might have been presented as power in and power out, which would demonstrate the limits of lower input voltage. These videos have been good to watch, and are good tools to make peoples plans on powering up with.

Nicely done. Good demo to show the effect of wire resistance on voltage drop.

For 16mm wire, voltage drop (V = IR) is 1.21V, power loss (I^2R) is 60W. So, if you're running high current on a long wire run, and you want it to be efficient, fat is where it's at. Fat wire, that is.
Mate best explanation I have heard - everyone should listen to your advice - particularly voltage drop.
Much appreciated

Awesome Vid Keenan, I have just finished my sons Canopy fitout with 12volt system and explained the importance of heavy cable to him! I did mine 3 years back and it works a treat. Thanks for sharing, we love your channel, cheers Pete
Thanks Peter!! I’m sure it’s going to be an epic canopy!! Good stuff thanks mate
Thanks for the explanation it does make sense and will help me next week when I go purchase and order/installation.
Thank you Keegan 👍🏼
No worries at all mate! Really glad you got something out of it!! Cheers 🤙🏽🍻🤙🏽
Awesome video mate, really helps a rookie like me, I'm currently covering to lithium in my camper, and just using solar. Thanks, love your work..
Thanks mate!! I’m still a rookie and still learn things too!! Glad you enjoyed it mate
What a bloody top little doco, great stuff. Very much a video everyone should have a look at. Cheers fella very good explanation
Thank you for this. I have been watching RV solar and other solar videos for a while, I got more information about how to 'set up' a system than I have in all the hours I have spent trying to learn about the systems.
You are fantastic, thanks for all the great advice....you've inspired me to get it right!!!
Thanks Peter!! Glad you got something out of it! 🤙🏽🍻🤙🏽
Thanks for taking the time to explain that in detail mate, that was excellent and confirmed what I believed I was doing correctly, was actually correct 😂
Good solid reminder to keep an eye on the panels and give them a cleanup regularly too. 🤙
Thanks for the advice and information 👍 Greetings from south africa 🇿🇦 😀
Hey mate how are ya garn!!!
Cheers
@@SarahandKeelanTravels All good mate 👍
Awsome video mate. This is a massive issue that van companys arnt addressing when they sell people these big 12volts systems for their vans like what happened to me. Cheers for the info. Very well explained aswell. 👍👍
Thanks mate!!! Since we have been working and R & D testing vans at urban we have now made 16mm standard on drawbars on vans! 99% of all other manufacturers still use 6-8mm
Great vid and tips here Keelan, it was good to see the difference the wire guage made in real practice. I use a lot of the cheaper Chinese type Anderson plugs & find some to be very dodgy, so proper connectors is probably a good tip too,as a suspect connector can give you variable throughputs as they move/ vibrate in transit, so when testing can appear to be ok,but when moving can greatly influence what can be drawn at the load end, meaning a fridge maybe working ok when you leave, but in transit it can be switching on & off & taking time to restart each time, so appear the fridge is not working correctly when in fact it is, voltage drop as you say, from thin wires or bad connections, Cheeers
Thanks mate! Glad you enjoyed it!! 100% sometimes you get exactly what you pay for. I personally think when it comes to solar there isn’t much difference between a panel that’s 1000$ and a100$ panel.. cheers Evan
@@SarahandKeelanTravels true that, but I also believe the flexible type are generally less reliable for various reasons, they seem to have a high failure/shorter life rate from what I can gather.
Their all Chinese, when do you point out the expensive Chinese stuff?? Or are you stingy when using Chinese in good light?
Even the good ones are generally made in China, it’s the manufacturing people who want greater profit who have the Chinese build crap units.
Great tutorial video I learnt a lot....keep up the good work thank you❤
from a rookie- thankyou, gonna make my life much easier for my upcoming build 👌
Great video Keelan. The only thing I didn't understand (as a person who just bought his first 4X4 and a trailer) - did you say you ran 35mm cables for your system? That's one heck of a wire.
Nice work Keelan.... Good tips and sensible knowledge for all... 👌
Thanks eddy! Glad you enjoyed it
Brilliant video. So informative. Thanks Keelan.
thanks Matt!
Thanks Keelan, great video, best I have seen actually. What size Anderson are you using? PP180 that can take up to 70mm2 cable, as the smaller PP120 can only take up to 10mm2.
Cheers mate means a lot! Yeah it’s a 175amp Ando I think! Love big Ando’s aye!
@@SarahandKeelanTravels No worries mate it really was top notch, Bewdy I will only use PP180’s is from now on in for 12 and 24 volt run’s especially if DC to DC converters as well - really good points you made - Cheers and fun travels!
Excellent vid mate. Subscribed. Great hearing people who know what they’re talking about talk about stuff. Do you see much of a drop over different 50A Andersen plugs?
Thanks legend!! Welcome to the channel!! Are you talking about smaller Anderson plugs?? Generally speaking the smaller surface area on the connection the more resistance and more loses such as heat ect, the bigger the surface area and the tighter the connection the less resistance, less loss and therefore less volt drop!!
The best advice is the simplest. Thanks mate.
Thanks legend glad you enjoyed it
Dirty solar panels could easily be overlooked! Great tip👍👍❤️🇦🇺🦘
That’s it!! Thanks Gail!! Hope you are going well!! 🤙🏽🍻❤️
Best explanation I've heard. Thanks heaps mate
Thanks legend
Thank you Keelan. Greatly appreciate your input. Just looking to purchase our first van and want to save where we can but also make sure it's quality and done right the first time. We've watched so many videos on what you get and how to do it yourself. Heading of to the Sunshine Caravan show to check some of these vans out. Soooo looking forward to hitting the road one day.
Good on ya mate!! Just gotta do your research and be armed with the right info and the right questions to ask! Go check out urban they are wicked aye
Excellent presentation! Cable size is #1 cause of insufficient charging/failure I've come across. The 2nd are connections. It's stunning how I've seen some connected.
100% copper is the best cable and lugs to employ.
Buy once, cry once.
Again, you really nailed it. Well done.
Now one about those cigarette lighter sockets...dump those things....maybe your next video...
Thanks legend!! Sounds like you’ve seen it plenty of times!! I hate ciggy sockets! The old Ando all the way
Hi Keelan spot on mate have changed my to cable throughout vehicle and van and the amps are all the go by the way mine is itechworld gear aswell so far so good
That’s good mate!! Build the 12v system on good foundations! We swear by our itech gear! Great bang for buck
Great video and congrats on taking the time to explain this topic in depth. As a marine mechanic / boat fitter for over 30 years, Well done.
Great summary of a complex topic. Thanks mate
Thanks mate!!
Nice one Keelan. Happy you mentioned regulator as close to battery as possible, proved I was right in an argument where mate reckoned since manufacturer fixed it onto back of panel not on end of cable that was where it “had” to be 👍👍
Thanks mate!! It’s a very important point!! Often overlooked!! Haha silly silly
AFAIK the regulators bolted on the panels are 240V output so don't suffer the same Voltage drop because there's so much less current.
Best explanation I've seen on UA-cam! Well done mate. Appreciate it. Cheers 🍻
Some ways to help teach these principles might have focused on cable resistance per metre for various thickness of cable. Then show the voltage drop across the cable run. Then the DC-DC converter might have been presented as power in and power out, which would demonstrate the limits of lower input voltage.
These videos have been good to watch, and are good tools to make peoples plans on powering up with.
