    Safety Considerations:

    In this system, I sized the fuse for the inverter. In most off grid vehicle mounted systems, this is fine. If you are pulling a lot of current through the fuse box, you will need a larger fuse or circuit breaker. Technically you could take out the 175 amp circuit breaker, and only use the main bolt-on fuse, but thats up to you and what gauge of wire you are using, and how you plan to use your system.

    I did not ground the inverter or the charge controller in this video. If the manual of your inverter tells you to ground it, then run a nice little wire to chassis or ground. Just one extra wire. Follow the inverter directions. It may or may not come with the wire.

    The large 2 gauge wire that goes to the positive terminal of the battery is black because that's all I had on hand. I could not source it locally. I did not think that it would cause confusion, but some people commented about it.

    The main fuse that attaches to the battery and protects the 2 gauge wire is specifically a bolt- on fuse. You can use a similar sized fuse and fuse holder instead. Use whatever you have available.

    I did not use heatshrink for the 4 gauge wire because I ran out. Heat shrink is preferable. Use it if you can!

    Merry Christmas Will. You are loved by so many types of people and beliefs that would all give you the warmest hug and are thankful for your personality that you hare with us all year long. You are a beautiful loving soul with kindness and compassion in your heart. I know you don't believe the same way I do in God, but I still find it necessary to be praying for you, your safety, and for you to be prosperous all year long. You are an internet friend. One I will never meet or hold. But you still make a real live impression that stays with me like a friend you can sit with and have heart to hearts with. Merry Christmas to a real friend in my heart!

    Very nice job Will.. But why did you use a black wire from the positive side of the battery to the circuit breaker? I believe it should have been red. And have a wonderful Christmas and New Year!!!!!!

    Excellent video Will! It’s nice to see a video so carefully explained.

    Great explanation of what it takes to setup a simple solar system! It's great to see what types of tools are needed in order to properly hook things up. Thank you so much.

    I know you probably don't care to be too technically specific on everything and it's an overview of how to do things but when you hook up this 12 circuit fuse block it's designed to have up to a 100 circuit feeding it and (I'm a little confused because on the blue seas website it shows a 125 amp fuse and service ) clearly it's less than the 170 amp breaker you have feeding it. It should be on its own circuit not on the same breaker that feeds the inverter. Also you forgot to mention that when you install an inverter in the same location as the batteries they have to be AGM or lithium batteries not lead acid because a lead acid gasses can corrode the internal components of the inverter. I'm not sure that fuse you installed on the batter is designed to connect directly to the cable without a proper fuse holder I've never seen it done like that I would have to conferred to the manufacture to see if that's an approved connection method. I'm pretty sure the fuse itself is designed to be supported on a Mega AMG fuse block and not mounted on flexible cable were it could break.
    It's great that you're making these videos for people but they will follow exactly what you do so be be be careful.

    again with the great legs and feet, this must stop. btw got the newest book, I'm learning very fast, next year i should be set up solar wise, keep, it up,just please, well, you know

    Hi Will
    you MUST start make money from all this solar theme. I keep in mind that you many time mention that you do not want "do this do that" but you can do you custom build ON YOUR conditions. But you defenytly must start make money "from this"

    Hi Will. Hope you had a lovely Christmas. Still kicking out videos during the holidays. I have your book and it’s absolutely great. It’s not complicated jargon. It’s like you are actually talking is through it. Great job. I have come to realise that for my camping pod I am not going to need an inverter. If I get shore power than great. But only want lights and charging points really. No appliances. So if that’s the case am I right in saying I do not need the 100-250 amp bolt on fuse. And in fact can do just an inline fuse 1.25 x the biggest load of the 12v fuse box? Almost sound like I know what I’m doing ha

    Excellent video Will. As mentioned in other comments, I wish I had this before I did our first 800 watt system last year. I found it awesome that we had the same 40 amp Epevers and Vmaxs in that system. We have since had those flat panels (7 out of 8 died one month within a year) die and swapped to a small class c recently. I am in the process of ordering the last few components for our new 400 watt system and we went with two 100ah Battleborns 😀 this time. Great minds think alike!

    Great video man!

    Thanks for your videos Will. Do you have any experience with the Blue Seas ACRs, and if so, which model would you recommend for an SUV with 130 amp alternator?

    Thanks much for DIY solar panels system.

    I'm going to compare the components of the system with the components of my system and then I'm going to do that analysis on what else I could do with it my "Solaris 12 Volt system" utra light utra compact.
