[@settlece]

Thanks for all your hard work and your videos. I'm using your content to teach me how to set up my solar.

[@Mikeb8134]

I think your goal is to make solar prohibitively expensive and impractical; if everything I buy from your recommendation is $10,000 the solar system is gonna cost more than the house

[@BsYtHandle]

Never before have I watched a tutorial in real life or via a screen that keeps the needle on my bullshit detector at zero for the entire thing. Truly remarkable.

[@youcanthide004]

yup, will is the Guru, NO NONSENSE!

[@yanstev]

I am an electrical engineer and have experience installing electronics in military fighter aircraft. I'm now retired and stumbled onto your KZbin videos because I'm playing around with building an RV solar system. You provide valuable information and I learn something with every video. Working on aircraft, all the tools, wiring, and components used are top end and super expensive. Moving to the hobbyist/consumer side, it is difficult to find information to find optimal/acceptable quality versus cost, which is why I particularly like your videos. I would recommend that you start a naming convention for you videos, like Year-Episode Number (e.g. Episode 20-01: Review of ...) so that it is easier to determine if the review is for a new item, versus something that came out three years ago. Keep up the good work and disseminating honest information on a rapidly changing technology and product field. Someone has to keep the junk-peddlers honest.

[@MasterChief4U]

Well Aircraft use 400hz and VFD.. I doubt anybody outside the aviation industry knows this. And baby once you been hit with 400hz you never for get it. You will have hair standing in its end and yelling 3,3 million Giga Watts..

[@Bajatrvlr]

I have to say, you just encapsulated just about everything I’ve told people for years... I’m a retired electrician who lived off the grid in Mexico for years when anything solar was astronomically expensive and hard to come by. So, I’m really glad to see someone with your qualifications take up the mantel of educating all the people out there who really don’t have a clue as to where and how to start...Good on ya!

[@DocJaeBass]

What about using type UF-B 10/2 with ground? I've seen it on several off grid systems connecting the panel array to the inside system.

[@mrmotofy]

@@DocJaeBass Stranded wire will work better. Especially for DC wiring

[@DocJaeBass]

@@mrmotofy thanks

[@danielwilson2109]

What qualifications does he have? Definitely has a bit of knowledge

[@truthbebold4009]

Thanks for sharing. Question about the copper-clad aluminum...just finished watching a Mike Holt video where CCA was discussed, along with the history of wire (Al, Cu, and CCA). There seem to be many misconceptions about Al and CCA (for a variety of reasons). I need to research more but Mike gave positive reviews for use of CCA. One thing left out in both videos (this one and Mike's) is skin effect (current flowing in the outer portion of the wire). So I believe skin effect is more prevalent at higher frequencies. In other words, no skin effect on D.C. and more skin effect on AC and greater skin effect on catv and such. Just wondering if anyone has studied this out thoroughly. Thanks

[@randallb7501]

your communication skills are impeccable

[@udmbfckx2916]

101 DC Wiring with Will Prowse.....A MUST WATCH! 1) He knows that not everyone will watch the video, so Safety issues first! Make sure it is 100% copper! 2) Cheap (but decent) Chinese Batteries? Yes.....But Cheap & underrated wires, connectors/lugs? NO. 3) Proper wire spec, material and quality - The 3 tenets of wiring - aka copper, copper, copper....PURE + Quality insulation. 4) Will talking about STRIPPERS (LOL) and cheap ones vs expensive ones. This is one of the most underrated subjects and one that for many feels like pulling teeth and usually ignored because everyone else is looking at panels, batteries, controllers and inverters forgetting that the wiring is what makes it work properly and safely. But I cannot re-state how important this is in preventing damage (fire) or even injury (shock, burn, etc) plus equipment and property damage not to mention performance inefficiencies. You've all seen the videos where he sets aside a good chunk of money on wiring. In this video he explains why and what to look for.

[@billietyree2214]

I remember that back in the 60-70s people were having problems with their house wiring because it was aluminum wire. Aluminum, under pressure, will flow (like tooth paste, but slower). So the problem was that the screws in the terminals were pressing on the wire, the aluminum, over time, flowed enough to loosen the connection, resistance from the bad connection built up, the wire heated to the point that houses caught fire. the cure was to retorque every electrical connection in the house every year or so. Another thing about aluminum is that it will work harden and eventually break if it is flexed too many times.

[@unstoppablezone4980]

I love this guy. Ok he rambles just a bit but it is from the heart. His book is invaluable. For beginners working in solar...get his book! It can save you from making so many mistakes, and it is down-to-earth and well written.

[@thomasnorman7016]

This is why I love Will Prouse videos. Simply the best information, clearly stated, with no ego and no agenda other than giving the best, trustworthy information on the internet.

[@Knoklsnedkr]

"I think this is for the advanced users." No, Will. It is very valuable information to avoid buying junk and making a firehazard. Thank you!!!!

[@patmitskey839]

Nailed It!!! Love what you are doing. I'm really old school, 1978, was when, I first started, welding and wiring... It's really old school, never cheap up on what you're doing.. Another FANTASTIC video!!!

[@squidlings]

Your happiness for that cable makes me feel happy. 7:55

[@koborkutya7338]

"...so you don't have to think and you will have a solid system" I love it Will, you obviously have no illusions about DIY people :)

[@sxtn102]

The details are important!!! Everyone has an opinion, some reliable, some not, but they're just opinions. They teach you nothing! I really appreciate when you explain WHY something is junk, or WHY using dissimilar metals is going to be a problem down the road. Then, when no one else is around, I can actually THINK thru a problem, avoiding the pitfalls because I know the "whys" of it. ( MY 2¢) Lynn

[@phonemd1]

This was an excellent video. Most have no clue how important the connectors are, or how to crimp properly........not to mention wire quality. It was nice to meet you in person at the van build!!

[@nmartin5551]

I’ve been a fan of will for several years. Now that I”m finally installing my solar I’m back to watching the most important video that I should have watched regularly over the years. (Yes, my memory is that bad). Now i need to go back and check my amazon order history to see what wire I will be replacing.

[@charlesrossman5426]

He Will. You are one of my absolute favorites on KZbin hands-down!! I do also watch David pox. He gets in pretty good detail. But I understand you more. Beef up the systems a little bit I really want to learn more about 24 V maybe even 48 V. Solar panel set ups. But I am going to be starting out in an RV and I would like to go 24 V because I am a mechanic a welder and a remodeler homebuilder. Plus a whole bunch of other things too much to list. But I love the way that you get so into detail and explain it to her three different for different ways whatever whatever it takes. You and Jeff Williams on my favorites on KZbin absolutely completely and you both live in the same city as my daughter. And yes I’m from Nevada also with another seven daughters and one son. Hate to say but my son was born in Louisiana where I am at as of today and will be moving back home to Northern Arizona or Northwest maybe Nevada again I do have daughters in Fallon and Reno. Sorry for all the details you’re one of my favorites OK I hope my son turns out like you you’re awesome

[@xavierpendrag0n]

I really hope more people watch this. It is absolutely important. I hear "oh but that will work.." a lot when people get cheap crap and want me to warranty work. I just tell them to let me handle providing the wire, luggs, ect, and it wont be cheap. The other option, well, there isn't one.

[@johnwera93]

Dude, you’re literally changing my life. Your simplifications are there and therefor anyone with half a brain can follow you. I appreciated your backstory as well. Great job learning on your own then sharing. I also agree not everyone should be trusted in the backstory situation. Keep up the information sharing.

[@mindovermatter3988]

I'm no dummy when it comes to any of this stuff and I'm currently building my own batteries solar systems and what not but I love how you straight to the point no BS and so truthful and being able to make money while playing around with batteries and solar systems. I know how fun it is in it's amazing that you can get paid for doing it. I bought your book because you seem very knowledgeable straight to the point and again no BS.

[@BillLowenburg]

Extremely helpful. I'm a DIY retired guy just learning how to build a system. This, your book, and your other videos have taught me everything I need to go ahead and put it together. It's really exciting to go from knowing nothing about a subject to being able to apply knowledge into a tangible thing you build with your own hands. Thanks so much, Will.

[@svs987]

I've had the same model stripper as you showed for nearly 40 years now - never let me down!

[@StevenSaltman]

I know this comment is buried and not very additive, but I just want to say this may be the best DIY explanatory video I've ever seen. And it's about wire. I literally bought every tool you demo'd. Thank you.

[@beckyspindler2153]

You're just shooting straight and doing your best to make sure we don't toast ourselves.

Thank you so much for reminding us or for some pointing it out

[@emariaenterprises]

I have been sharing your videos with my friends, so sometimes it looks like I’m not watching all the way through... but it’s just me looking for the various videos and passing them on. I love your stuff.

[@jeremycarey5987]

Couldn't agree more. A friend of mine suggested going to a welding supply store they sell the best wire and lugs for a good price. They also sell it to you by the foot so you can get exactly what you need. Has worked very well for me for years now.

[@MsRotorwings]

Great idea! Thank you.

[@DCGULL01]

This NEEDS to be a highlighted video. It is CRITICAL to a successful DIY project, Will! I love your builds, and, I've been subscribed for a year or more. But, I've never seen this video until TODAY. Excellent explanation of cold welds, and, WHY no copper clad aluminum in ANY connection. Cost vs. safety is clear. Really AWESOME & so needed by people who get comfy with the idea of building their own.

[@bigbearprepper]

Great job! Your videos are getting better and better. Sharing your knowledge an experience is the best on the internet. Thank you.

[@danbrown586]

For the automotive-type crimp-on terminals (the ones with the red/blue/yellow plastic insulation on them), the best product to be using are true PIDG (plastic-insulated double-grip) terminals made by AMP among others. These bring a few advantages to the party: (1) the ferrule that crimps over the wire is brazed shut, so it can't spread on crimping; (2) the insulation material is nylon, rather than the PVC that's used for most of the cheaper terminals; and (3) the metal sleeve inside the terminal extends out over the insulation of the wire, and is crimped onto it, providing proper strain relief. A ratcheting crimper with the right dies is really the proper tool to use for crimping these, as it will apply both crimps simultaneously. You won't find these at Lowe's or Wal-Mart, but of course Amazon has them, or any decent electronics supplier like DigiKey or Mouser would carry them.

[@kevin3434343434]

It's very enjoyable watching someone who is so passionate about a topic. Great video, thanks!

[@williamhustonrn6160]

When I did my Solar Install, I used welding wire as you mentioned, but for connecting end lugs, instead of buying connectors specifically, I bought 20ft roll of copper tubing from hardware store that barely fits over the cable ends for $20 and used a $40 hydraulic wire crimping tool I bought off amazon for crimping them to the wire, then I would silver solder the connection and add shrink tube that has the glue to the ends, smashed the end closed and drilled a hole per whatever size bolt I needed to fit. I found I could flip the crimp plates on the crimping tool backward so the flat sides facing each other and that would allow me to use the hydraulic power of the tool to flatten the ends very easily. A trick someone told me to try that actually worked was to go to the lowesforpros site and signup for an account, then you could buy the welding cable from them with the pro discount for $1.79/ft, I paid $90 for the 50ft rolls of the 1/0 welding cable they sell on a spool. When i helped one of my friends do his solar install, we used the same hydraulic crimp tool I had for his cables along with copper tube end method, but instead of taking the time to silver solder all the wires like I did, he bought some tin soldering bars from eBay and melted them in a soup can on a little camping cooker he had and completely dipped the entire connector end and wire up to the cable insulation in the tin to fill the connector with tin and then we drilled the holes in the ends.

And am now in a lawsuit with the company we literally had about thirty seconds to get out. Just be careful with dealing with cheap lithium

[@neliosamch3195]

Yes, it is important to have several levels of safety, new or old cheap or expensive batteries. Malfunctioning and or mistakes happen. We can't blame no body when we do it at own risk but ourselves. What looks easy and simple to do for Will may be difficult and complicated for others. Always ask questions when in doubt. Did you have fire extinguishers and water sprinklers in place? Thanks for making others awere of the danger lithium poses.

[@Bashkir097]

I'm enjoying going through your back catalog. Just a note about the marine grade waterproof crimp connects - while they "work" with normal crimpers they should be used with a specialized crimper. The anvils have an extra step in them if I remember correctly. It's been a while since I've had to worry about them and my memory is getting a bit fuzzy otherwise I'd post a link with details. It's definitely a boating nerd thing.

[@dianeattaway8733]

So true with aluminum! 30 years experience repairing damage done from aluminum/copper connections. Sometimes the connection explodes. Sometimes molten metal. Sometimes insulation burned all the way into conduit. Sometimes massive arc flash. Always a lot of fun repairing the property damage...

[@4philipp]

Excellent video ... educational -- and nothing caught on fire ... LOL... CCA wire can only push 67% as much as the same size in a true Cooper wire .. meaning that a 8 AWG COPPER wire is about that same as a 4 AWG CCA cable ... Thats the biggest issue that we see in using this ... We have seen SEVERAL CCA cable catch fire ... never have seen COPPER catch fire ...

[@eastsideeddie]

I bought every bit of wire in my system through your web page, so I know I'm good. Also got my tools based on the book. That red handled wire stripper worked okay because of the adjustable tail stop. I had to move it back about 1/4" for some of my wire but it stripped everything really well. And the ratcheting crimper is great.

[@alec4672]

Sometimes on a really exposed connection I'll use an anti corrosion paste on the outside of the copper lug. So crimp the lug just as you said apply some dielectric to the inside of the heat shrink and shrink it down. Mainly to prevent water or dirt from getting in anywhere the heat shrink didn't quite seal up. If you have the more expensive heat shrink with the glue in it that's not necessary but it still makes me feel good. The contact between the wire and lug should always be a dry cold weld as you said though.

[@OTOss-fi2el]

For my solar projects I go down to the local Recycling yard and they usually have several dumpsters full of scrap wire you can root through and buy it by the pound... I get all my welding cable there good links and like new material.... as an electrician I have access to lots of scrap and other goodies I use THHN2 to for all my component connections... When making connections on some big 2/0 cable or other large sizes I will put the wiring connector in my vice on the bench and use the vice to crimp the logs.... Solid connections are a must to resist the vibration when RV traveling down the freeway or a dirt road... and I always upsize my wire nothing less than 1 gauge from what is required....

Awesome video. Can you do a video on battery levels during usage? I have a 30 min dish washer that uses 1100w when it starts and then 60w for most of the remaining time. If my battery is at 13v it immediately drops to 11.1 and then minutes later when the machine starts using 60w the battery jumps to 12.1. So it’s instantly empty then it has 50%. Why is this so?

Very good explanation about cables and wires. Couldn't have said it better myself, as an "old certified electrician". You mention China, which is very strange when it comes to cable and wire. As little as possible of raw materials should be used, even the varnish on the winding wire for motors is to little. I have been there for almost 17 years. I asked a manufacturer what the meaning of CE mark was. China Export he said.

We have been repairing cars for of 30 years. We have tried and used them all. For small stuff there is one that shines above all. The Bellanco Super Crimp III. Great too. Not crazy expensive. Once you use it you won't want to use another.

[@scottboyce]

All great advice, although true “gas tight crimps” are very unlikely with tools shown here. Actual gas tight crimps are usually formed with oval dies or actuating 4+ point hydraulic tools, and the tool/die and lug combo has to be certified to work together.

[@RobertWilliams-pc2ur]

Excellent Video. Required viewing for anyone building their own system. I want to point out that while everyone focuses on wire gauge, as they should, do not forget to check the insulation rating of the wire. Do not use wire that has insulation only rated for 12 VDC on the 120 VAC side of the system. Make sure the insulation is rated for the higher voltage of the AC side of the system Some SO cord is rated at 300 VAC and most of the THHN insulation is rated for 600 VAC. The insulation rating should be printed on the wire.

Good video, also run solar pv cable through a uv rated conduit for full protection

Can 10 gauge solar wire can support 1000 watt (200w x 5 panel in series) ?

Any chance we can have you do a build video on a jump start battery for a car. Maybe could be multifunctional. Thanks

You need to go back and watch ALL of Wills videos. This young man went from being homeless to now he owns his own home and has a great you tube channel that offers LOTS of help. He is a great example of rags to riches and he is the smartest young man out here doing these videos. Again go back and watch all of his videos. I don't even know him but am very proud of what he has done for his self and how he has changed his life. God Bless.

One thing I've found it that the ampacity rating for welding cable seems to be higher than "regular" copper wire. For example 2 awg welding cable shows me an ampacity of 200 A for a 50' circuit where as the more commonly referred to chart shows I should have 2/0 or higher depending on if the circuit is critical or non-critical

Would have you as a surrogate son, love your honesty. If you ever come to Australia, you are welcome to come stay with us. You are a younger version of my 80 year old husband.
