30kWh Home Solar Battery from Tesla Model S Battery Modules


We show step by step how to assemble a 30 kWh Solar Home energy storage battery using six Tesla Model S Battery Modules – the right way taking full advantage of the Tesla BMS boards ON the modules to monitor voltage, temperature and perform active balancing.

The battery is enclosed in a Wiegman NEMA carbon steel enclosure.

    I,d like to see a system using the tesla battery, batteries for a sail boat!!! Much of it 12 , 24 and 120 v. Huge market considering most are using lead acid deep cycle or 3 to 5 $1000, for each battle born type batteries. Save money live better!

    Heating, yes. I can see that here since we have days below freezing in winter time…. A hot pad in the battery container should do well enough. (just keep things above 40 for battery happiness.) When you have multiple battery packs in parallel, the current load on each should be fairly relaxed. If the pack were handling a couple of welders.. well I can see that possibly needing cooling. I don't do welding..<G>

    Interesting information a number of new companies have formed in Sparks Nevada that claims to recycle over 80 percent of the lithium ion battery materials from used cells. They plan on designing their own replacement cells that will be compatible with battery modules and cells from other companies or resell the materials to 3rd parties to make their own batteries. I really think this could become a huge business for independent companies who build similar systems like yours Jack. Right now people have to buy battery modules from Tesla and Chevy accidents. It would be great if they could get batteries from independent suppliers eventually as the business grows I am sure it will happen. Another you and Rich Rebuilds need to get together sometime it would be a huge episodes with Rich's 120,000 fans. https://www.youtube.com/watch?v=9XZEDHv9l2k

    Hey Jack Great video what kind of amp draw could be pulled from this battery pack? What i mean is in a normal 4 bedroom 2 bath house with all electric house how long could it run? I understand there are a lot of variables, but a rough estimate is what i looking for.

    Hello Teacher ;
    with all your respecte you are the most great one's in the Net who "control EV world " I'm watching your tutoriels since 2015, I were one from the few visitor ." Iam car repairer" since 2014 , I BEEN INTRESTED IN EV subject that are available in the Net, i'm your student from MOROCCO I learn english in "The American Language Center of Rabat" to i can understand you and progress in my level I wish you heaven and the good life with your family and all who you love , for me i wish been the first engineer who started that project in africa continent ,Thank you so mush .

    The red fuel pub at the beginning of the video has it got a plasma ball on top, if so that is amazing and could you please show it, If you want to sell and ship it to the UK I'd to love it, I checked out your website yesterday funny because I how found this channel I was watching a guy converting a Honda Civic using one of your vehicle kits you have some amazing stuff for sale on your site, love the company.

    Thank you for the information about destroying cells at 32 deg. I bought one of these modules and I have been using it for 5 months and I love it. Now I am working to build / buy a BMS for the system. I am debating between using the built in BMS / getting an off the shelf BMS. Being able to use the onboard BMS sounds exactly what I want to do, I have used ardruino with my CNC machine. I will compare the cost of this setup verses buying one off the shelf. Take care my friend you have a wealth of information.

    That starting intro I was expecting something like Warner Brothers or some of the major movie productions lol.. I kind felt I was about to watch a movie 😉 good stuff by the way

    Just curious why you would put a fuse on the negative terminal. As shown in the video he fuse would clear a overload or short but the circuit on the line side of the fuse would remain at line voltage. Where as if it was at the plus terminal the same overload and short circuit protection is there but also the circuit on the load side of the fuse is at zero potential.

    I appreciate your videos as I am looking into the feasibility of converting a 26' cabin cruiser from gas to electric utilizing Tesla components. As I watch your videos I see that you can supply a wealth of knowledge, information and components that I would require to undertake such a project. Maybe I missed something but I have not been able to trackdown in your videos if you have developed a harness for utilizing the tesla battery modules in series (400V config). I saw the conversion of your cadillac truck and the VW vehicle but I do not recall seeing anything specific beyond discussions about final battery placement or the evtv harnesses for those vehicles. I am also uncertain as what charging hardware will be applied to those vehicles – are you going to use the tesla chargers (like Tesla Model S (2012-2015) OEM GEN 2 Sealed Charger Part# 1014963-00-G) or something else ?

    I like it 🙂 That's funny you're using a Schneider inverter, that's whom I was looking to use, they have a solid trackrecord and a great variety of product ranges.
    I'll probly set the HiVolt at 4.25v. I like how you put in the sensitivity anomalous event conveyance, nice touch.
    I'll probly loginterval like 15 minutes(runaways take time).
    Think you could do me up for $9,510? I figured 9,000 wouldn't be feasible for the assembly required, mine as well aim for my lucky number as a counteroffer(know it'll get a very good resting place and sustain my modern way of life).
    Did you get zapped at 58:17 or just poked?
    Appreciate your vision for safe lithium implementation at a fair price just keep at it 😀
    I feel you're a lot like me Jack first you have an idea, then you iron it out, seeking points of failure to eliminate, Nikola Tesla would be proud.
