    Thank you Will. The diagram you drew there is very clear, precise & easy to learn. I have watched many other RV's solar-electrical wiring set-up videos but I couldn't catch the details how they were actually connected to each component/equipment. Thank you very much.

    Great video. That's alot better to understand. Wiring diagrams are much easier to follow. Good tip on not draining down the batteries too much. The system I'm considering uses 8 x 6v batteries, with 4kw 24v invertors, an 80A Controller and 6 x 260v solar panels.

    Well done young man! I’m buying a new camper and want to put 2 panels on top. I’m thinking of going with 2 6volt battery’s for a start.

    4:27 in the reflection on his dry erase board I see what looks like a refrigeration compressor, is that what it is?

    13:33 I heard it's bad to make a spark near the battery because the gases can explode, even with just a small amount. what if a fuse were to blow it makes a spark, right?

    While we don't want a "fire", we also don't want a "bomb" either…

    How should I safeguard this?

    Finally! You are bright boy! This was very easy. I have multiple degrees and could never understand it. Thanks!

    Ok, first of all, I did not need to buy your book, I am an ex Navy Electronics Technician and Reactor Operator, and I have a BS in Industrial Engineering, after getting out of the Navy, I worked as a Field Engineer for Northrop Grumman fixing all kinds of Servers, computers, networks, laptops, and huge plotters and printers. I bought your book. Because not everyone has had those opportunities I have had. I LOVE the fact that you have made this available in the Kindle format, as I now live in a Motor home and am disabled I do not have room for books. So in complete support of your efforts, I have purchased your book. You are doing great work with this resource. My compliments, very well explained and put in a way that most all folks can understand. Cheers and God bless

    “you can cause fires, and that’s really bad” LOL!!!

    THANK YOU SOOOOO MUCH for this very straightforward explanation. This has (probably literally) saved my life.

    How much crap have I watched to find someone who explains it as simply as this. Lots! lots and lots of completely over my head dribble. and this one video has paved the way. I shall now be driving fearlessly into potentially fatal electrical stuff like a hero who knows it all! thunderbirds are go.

    Hi Will, im trying to add solar power to a cottage, mainly to power a Portable ac unit. It pulls 110 V and 25 amps. what kind pf system will I need to accomplish this?…

  12. Date: September 29, 2018 at 08:52

    My MPPT Controller has a Bluetooth APP. I got really confused that once the battery is 80-90% charged the Watts on the Solar Panel started dropping.

  13. Date: October 8, 2018 at 09:48

    Hey Will, just found your channel & wanted to say excellent explanations here & subbed as I am not completely unaware of what I want to be able to install a system in my camper but, I have learning to do & like the way you educate. Great video, will be checking out much more & your website…thanks!
    Does cold, as in frigid Canadian winters, affect the panels?

    Fantastic! For the first time I understand what you were saying in your book. I'm one of those people who does best watching someone do something I've never done before. Fortunately, I've done enough wiring to understand your connections. I didn't really understand how the controller worked, however, as it seemed like I already had that capability on my Kodiak battery. I have other batteries, however, that don't have that capability, I wanted to use to keep my Dodge Grand Caravan's battery topped as it seems to discharge really quickly when not driven. So thanks for the help. I feel much more confident that I won't blow anything up now lol.

    Perfectly explained, My expertise is wiring cars, so the 12 volt side was no problem, this was perfect for everything on the other side, your book is in my cart ready for my next order. Well done!

    Thankyou. This is exactly what i needed to figure out how solar power can work for me

    Well worth watching for a solar novice like myself, got my kindle version of the book, you never know when you may not have Internet to re watch. Although my background is in computers, this video was a great help.

    Hey Will, can you do a video about adding a 120V system using a three prong RV style setup? I want to make a weekender light use shelter/paramotor transporter using a small enclosed cargo trailer and would like to have the ability to stay at RV parks if necessary and be able to plug into their three pronged RV hookups. It should be pretty simple, just the socket on the outside, a box on the wall and some standard 120V outlets.
