Be sure to check with local laws and regulations for your electrical code. Some places are more strict or lax than others! Many places will require conduit for the PV conductors.

    Parts list and blueprint for this system can be found here: www.mobile-solarpower.com/48v-complete-system-blue… Be sure to check with local laws and regulations for your electrical code. Some places are more strict or lax than others! My system is not connected to the grid in any way, so I am not going to get an inspection. This is considered the same system as a car battery connected to a 12V inverter. There is nothing special about it. If you need to earth ground your system, have an electrician assess your environment and system and figure out what is most appropriate. And any other special safety equipment. Always hire a professional if you do not understand something! In the blueprints above, I go into this point with more details.

  • As a home inspector and residential contractor with 15 years in the housing industry, I can say I am impressed. As I was watching the video, I had several concerns/issues, ready and waiting in my mind. Will addressed them all one by one in very satisfactory manner. Main disconnects, grounds and neutrals being separated, or not being separated and so on. Top-notch video.
  • Will, I can't thank you enough for making this series. I've been on the verge of buying and building a system for a while and this fits the bill perfectly. The way you lay everything out is perfect for a beginner that has only done minor electrical work in the past. I now have the confidence to start ordering my supplies and gaining my independence from the ever-rising electrical rates.
  • This is incredible Will, I can't believe how much the systems have changed in just a few years.
  • @brokerbud
    Fantastic job Will. A ton of work went into this video. The information is clear and concise. Your blueprint on your website is super detailed. Links to all the parts are included. There is nothing missing. Outstanding work. Thank you for all you do.
  • @joub5
    Will, Thank you on the outstanding jobs you've done on your videos. Essentially this series. You really knocked it out the park. Your getting a lot of praise for your work and deservedly so. I'm just adding to the long list. By far the best on YouTube on the subject matter.
  • Amazing work! Thank you so much for making this series. I’m going to build this exact setup. You’re the best Will!
  • I’m very impressed each time you build one of your systems. They are so clean and simply set up anyone can do it. You are amazing explaining everything including the mistakes possible and all the safety precautions. I always recommend your channel to anyone doing solar.
  • @aussie2uGA
    I really appreciate the time you spent making the list and video. The bonus for all of us is that if/when you find a specific component is not "aging well", you can update the list or make notations for improved updated products. Thanks again!
  • @N8TheSnake
    Will this is one of your best videos. You just clearly illustrated the products and installation methods necessary to realistically build a completely off-grid electrical system that can power ALL THE THINGS people expect in a modern home. Really nicely done sir.
  • @scottc346
    This is so awesome. My wife and I are planning on our dream off-grid house and this will defiantly get us started if not do the full job. Thanks again for all you do and provide to us!!!
  • So amazing! I can't believe how far this tech has come in just a couple of years. You're videos are very encouraging and I can't wait to get started on my own project. Thanks Will.
  • This is essentially the exact off grid system that I have wanted to build for the last year or so. THANK YOU THANK YOU THANK YOU!
  • @benjones8977
    Thanks Will! You’re getting better and better at explaining this stuff. I can’t emphasize enough that we need to get everybody we can off grid for what’s coming! 🤙
  • @jar349
    If you are like me and learned a lot of what you know from Will, just remember to check with your local zoning officer before you buy. I purchased an offgrid system under the assumption that it would not need to be code compliant and then I learned otherwise. My municipality did not care that my system was ground mounted and totally off-grid. They are requiring that I get zoning and building permits and an inspection before I power it up. If I were doing this all over again, I would get the zoning and building permits that give the "ok" for the equipment I want to use and then purchase the equipment.
  • @proverbs3147
    I've watched this at least 20 times. 1) I learn something else each and every time. 2) I get super excited for my system each time!!
  • @MrBbeck317
    Will - thank you for your work! I credit this video for giving me and my family the confidence to DIY our off-grid project. And I’ve watched it at least 25 times on my way to a successful install. Today we turned the lights on and all went great. Exciting day. THANK YOU!
  • @guaranimike
    My son and I each just purchased this system. Excellent video, Will! What timing! Hats off to the folks at Signature Solar who make this purchase pain free.
  • @andreb877
    Will, you are the man. I'm an engineer but you have taught me so much about "real world" solar installation it ain't funny! Thank you for your videos and God bless!!
  • @robkelderman1572
    Bought that unit and was happy to see you tested it and gave a thumbs up . I do agree they are very simple to wire and and Singnature Solar has 24 /7 help for anyone and they notify you on any issues to be rectified . I am looking forward to have my system running this November when my house is complete . You do a great job explaining , and I feel most people can relate . Cheers Rob
