ONE MILLION views!! I never expected this video would go that far. Thank you everyone for the support, feedback, and ideas!! **NEW** Follow our Twitter page... twitter.com/LithiumSolarYT

I am an electrical engineer, product developer, and maker. I gotta say, this is one classy build that anyone would be proud of. Great job, and excellent presentation.

I am 74 and we owned one of the first solar houses when I was about your age. We bought the house new and there were huge tax credits at the time for "going solar", however it was not solar panel electricity. It was pre-heated water for the water heater, plus solar heated air for the furnace in the day time, plus heating a large closet full of rocks to get hot and provide heat at night. The builder did not roof the house and then add the panels, but mounted the panels then roofed around them. After 4 years of fighting roof leaks, we had them removed and went back to "normal" operations. I would love to play with what you have for my camper, however, at my age, I no longer enjoy tedious work. I have added 3 100 watt solar panels but use them with 4 deep cycle batteries, 2 on the camper, and 2 for external use. I would enjoyed building your project if available in my younger years, but not anymore. Sure enjoyed watching the video though and it refreshed my electrical knowledge from my days as an avionics tech in the AF.

There are 2 amazing things I noticed about this video: - He literally tested 390 cells and found out their capacity on an individual level. That requires enormous amount of patience and labour. If one adds the labour cost to do all these things, the final cost would go to $1000 - He does not wear gloves while soldering. Considering that it is a 1.7-1.8kwH battery pack, this requires serious confidence on oneself Really, a fantastic educational video. Definitely deserved the 5 million views.

Dude, you killed it 💪 this definitely looks like a build you poured your heart into. The attention to detail and research is immaculate. Big ups man 👌👌👌

32:34 "I do apologise for the amount of effort I've put into making free, high quality educational content for you," Alright, we'll let it slip this time, but don't let it happen again! Awesome video, this was very helpful for an upcoming project I have. Thank you very much for making this!

Nice, don't apologise for the length of the video,, the detailed instructions are excellent and will help anyone who wants to do a similar project or even a not so similar project using some of the same parts for that matter!

I enjoy this because this specific project is a rebuttal to everybody that says lithium batteries are an environmental nightmare, but you can recycle them and this is a prime example of the recycling process or at least one of them

"uh you can pretend this is a vice" got me 😂

Why do you apologize for a long video? Are people usually on a tight schedule when watching KZfaq? Haha! Keep those videos long and awesome!

I didnt understand a thing you said and I enjoyed every minute of this video.

Thank you for the outstanding video. I am in that stage where I’m finally understanding how this stuff works and your video helped me a lot. Make more please!

That's a phenomenal build! I'm newer than a newbie and wish I took electronics in school. Your instructions were well delivered. Such a cool project. I'm going to ask a experienced friend to assist/ coach. Thank you!

It would be cool if All DIY videos were this well laid out. Enjoyed all 33 minutes, no apology needed.

Dude, considering how much info you packed into that half hour, you have NOTHING to be apologizing for. That was an awesome build, and I'm glad you took the time to break it all down for us! Thank you for such an informative video!

Thank you so much I'm an electronic engineer and this brings me back to my collage days learning about a/c and d/c and sodering love how you walk ppl through the process

It's so beautifully made.. neat, clean, systematic with all functionalities I would say.. one can't ask for more than what the generator is capable of. If it was me, i would have made it a good business idea. Awesome job buddy. A lot of hard work has gone into it and it deserves as much appreciation. 5 stars all over 👍

It didn't even feel like 33 mins. I saw the title, found it interesting, started watching and here we are 33 mins later. Everything was spot on and perfect. Clear, easy to understand, easy to follow. Good stuff!

I actually didn’t mind the video length one bit! Top notch presentation! Like the build, very inspiring; great effort. ⭐️⭐️⭐️⭐️⭐️

Very comprehensive. No complicated academic jargon. A good tutor for a quick on the run training for evryone. Bravo. Another 1M? Easy.

Great video, I've used this for reference to several people including a few building off-grid buses and a mobile IT center. They were all going to use lead-acid batteries until i recommended this type of set-up. One recommendation I'd make is using XT90 connectors and tinning the leads before applying heat to the connector. It will allow you more solder w/o overheating the plastic.

This is who you want as a friend during a zombie apocalypse.

I just saw some random dude in youtube making a massive diy solar generator for thirty minutes saying things i wont ever understand in a thousand years. and yet i still enjoyed every second of it

Phenominal video. I couldnt pull this off in a million yrs

Great video- no need to apologize for making a great video! Very well done. Nice build, nice editing, nice narration- really enjoyed it.

There are some very intelligent people who have the gift of explaining what there doing as well, this person is one of them.

This guy is amazing Ever notice when someone knows what they are doing, they make their work sound simple and straightforward?

Wow just an amazing video , the fact that you just made your own generator from scratch. I didn't not care the video was long , i watched it every second of it. I read your disclaimer, you said your not a professional, you are right, you are beyond that! Straight Genius status RT! Anyone would be lucky to have you in their group , if there ever was an apocalypse! Only feedback would be give yourself more credit than you seem to give yourself, for what you do. Continue Stay humble my friend! Asking for feedback and constructive criticism, is a sign of high intelligence. Truly inspiring!

There's nothing wrong with being thorough no need to apologize thank you for what you do you're encouraging me to TAP back into a long lost passion of mine

If society collapsed, I want this guy on my survival team!

While I am interested in--intrigued by, actually--electronics, I know next to squat about the field. I DO know something about effective instruction, however, as a retired university professor with a Ph.D. in Instructional and Curriculum Theory. In my 40+ years in teaching, I have found few graduate students with your natural grasp of instructional design and pacing. Excellent job! I give you an A+. Keep up the good work, Teacher.

Superb. Several years ago I was thinking of something along the same lines, and about producing a consumer product brand 'Plug In Solar' where the panel and battery pack are together in a nice neat stand on castors that can be turned into a good orientation to maximise charging. That said I have non of the skills to do any of that, it was just an idea. Your skills and knowledge are off the charts!

What a brilliant video, thanks for creating it! I had begun to get ideas of making a sustainable power pack out of discarded batteries and dynamos, this has made me realise that I have a LOT to learn if I want to follow through on that idea. I can just about manage rewiring a plug!

This is one of the best tutorial videos I’ve ever seen.

Old school youtube I have missed you.

Dude, this is one of the few video in youtube that worth every minute, Thanks!!!

Having worked on a variety of electrical systems and projects in the last 30 years, I found this video, informative and not too long. There was obviously a lot of research involved, and a lot of knowledge transferred in (what I thought) a short amount of time. Great Video. BTW it's now got over 1.8M views. Well done.

Don't know what any of this meant, but this is mad entertaining!

Thank you for a comprehensive video, it is especially good to hear all of the reasoning in your design decisions.

Dude, awesome! Very thorough. Glad I found this. I appreciate you explaining your decision making on everything you put together, especially for someone that is trying to soak up as much information on this. Thx!

Love it! At 60 yrs old, I find it difficult to find folks in your age group that are as intuitive, intelligent and common-sense oriented as you are. Your narration was succinct and to-the-point with no nonsense. It felt like I was watching a guy that just wanted to share his knowledge and not someone trying to make a buck or show off. Thanks for the video, information and down-to-earth git-r-done style. Well done, good sir! Well done. BTW: If you aren't an Extra-class Amateur license holder, WHY? You'd make a kick-ass HAM!

As someone with a degree in electrical engineering and physics, I'm super impressed with the depth and expertise in this video and can vouch for its accuracy on most of the included topics. Definitely one of the best videos on this subject I've ever seen, well done, really enjoyed it!

So I watched this with the thought of building my own solar generator using 9v and some infuse line you took me on a road trip lol

I'm not planning to build one of these. The value of this video for me was that it served as a simple, no-nonsense description of what's inside an average portable power bank, kind of like demonstrating the back-engineering of one. In that context, for me it was super informative. Maybe one day I'll work under the supervision of an electrician and actually build one, which seems like a great (and money-saving) project, worth doing. Thanks a lot for this.

Nicely done! Just a suggestion for the temperature sensor: Run that thing withou ventilators running for as long you are comfortable. Take a picture with a thermal camera to find the hottest spot. Place the temperature sensor there.

It would be safer to have the temperature probe in the exhaust flow. That way the fan doesn't stop once cold air came in, but only once the components aren't hot enough to heat up the air stream anymore.

Super late to the party, but thanks for this video. I followed your general approach and built my own 2.7 KWh solar generator over the summer. I found a tool box with wheels, a 3kw inverter, and added some QOL things such as rubber padding for shock, working lights, and a momentary switch and power resistor across the main breaker to prime the inverter if it's off for a while, but your design is solid. Tested and charged it through the fall and winter, but can't wait to do some field tests once it gets warmer, e.g. camping. Thanks!

Amazing!! very thorough and explicit where needed. This is the type of people the algorithm should compliment.

Great video. Seriously. Length doesn't matter when all dialogue is informative. Long videos that include unnecessary info is what is annoying.

That was great! Super interesting.

This is a really well-done and brilliantly presented video. As an degreed engineer, I commend your excellence!

Award Winning Presentation. You are a very talented person. Well done and Thank you!!!

Very nice! This is the most thorough and technical solar/battery DIY project I've seen in a while. Mad skills, clean packaging and attention to detail 👍🏻

"I don't have 240 in the garage" That seems like a much easier project than what you've already undertaken.

Amazing Project and Thanks for helping us to find cheap batteries and other equipments.

New to exploring solar power, but really enjoyed your build. A longtime sailor with a 40 year old boat. Solar is a new idea for the boat and myself...

I wish so many others with great information to convey were as good as you at speaking clearly and knowing when to fast forward. Thanks for sharing this way.

Dude, I really enjoyed the video and the length was perfect for the amount of information. Shared this with my bud and when I visit him next time we’ll try and duplicate your project. I was really impressed with how everything fit so well into the box, just enough without a lot of wasted space. I appreciate your work, thank you!

I really wanna do this now and you really left no questions left unanswered

The length of this video was 100% worth every second!

this has been one of the coolest videos I've watched in awhile. Well done sir, thank you for sharing!

I couldn't even begin to imagine being as knowledgible as this guy. To me electricity is just "phone workie juice." Keep doing a good job!

I fully admit, most of this was over my head, but you seem to know what you are doing, and made it sound very simple (to someone smarter than I)! Good job! 👍👍

Congratulations for this amazing knowledge sharing! Also kudos for such patience to produce this great video! I could not criticize anything as far as you were aiming to be cost effective as you explained. Again, thank you for sharing!

This is certainly one of the cleanest looking DIY builds I've seen. Nice job.

Wow even though I’m not so good with electronics and I could really grasp about 1/3 of the whole setup it’s cool trying to learn when someone lays the information out well. Thanks man. One of these days I’ll figure out how this stuff works for the most part. I was already confused when you hooked up the negative and positive batteries in groups lol

Dude you are so down to earth chilli milli, I could listen to you for hours. Amazing content you are providing here :)

Number of views : It's uo to 5,316,746 views as of today May 12, 2022, at 2:30 a.m. MST. Hi, I know zero about electricity and anything presented in this video. But you have encouraged me to look into this as a V-E-R-Y longterm project to see if I could build one of these solar generators. (I'm 81 years old and need a project like this to stimulate my mind.) . . . . So, . . . I have a varied background of work and study experience, including old computer main frame S/W Operating Systems, and other endeavors. Your presentation is SUPERB. You've given me a new interest to feed my curiosity. Thanks.

Honestly I’m not gonna build this, but I watched the entire video. It’s interesting.

This was the most concise and informative DIY videos for such a build. I'm definitely following this guide for my own DIY generator build.

Very interesting. One of many old men that thought I could ease on out without learning about systems to produce electricity other than plugging in to the 110 volt socket. But the way things seem to be going in this country we need to adapt to the possibility that we have to be able to change with the times. Thanks for the video, very informative.

This is the best video on the topic of building a small battery.

You cleared up a few things for me that I had been struggling with, so thank you very much for your work. Still getting my head wrapped around bms components. I'm absolutely fascinated by all of it and I hope my rv project can be half as beautiful as yours

This is a great video and your very good at showing and explaining what you are doing and WHY you are doing it. Thanks for putting this together.

We thank you for this video and guidance regarding battery making.

Wonderful piece of art. It is beautifully made

This video is so well done that I've watched the whole thing - even if I do not plan to do this ever myself. Stunning presentation!

This is an amazing build and a very cool video. As much as I’d love to follow along with you, I don’t know nearly enough to do it. It’s fascinating to watch, but outside my skill level. I don’t know if you’d be interested in producing videos like this, but I’d love to see a series of videos for small, basic, starter projects that build up to something this massive. I’d love to build a battery pack for charging my phone or laptop, even if it isn’t cheaper than a store bought one, just to learn - and slowly work up to something like this that could serve amazingly in an off grid, or emergency scenario.

Wow. Thanks for putting this up dude. Excellently done!

This is by far one of the most pedantically made DIY videos I have seen on KZfaq. Thank you for the perfect video tutorial!

not even a project i was contemplating, nor do i intend to build one myself, loved the video. Just stumbled across it in the youtube rabbit hole, i definitely enjoyed it and i'm very pleased with your explanations and duly noting when and where special caution should be exercised. Great job explaining "the why" behind everything. There is usually more than one way to do something, in those cases there is sometimes a best way to complete the objective, but there is almost always a worst way to complete the objective. Sometimes experience is the only way to find the best and worst ways, but you are very mindful of good practices and do well to point out, to the viewer, your explanation as to why you did or didn't do something. Great job! Awesome build! Keep it up!

Absolutely great presentation of a worthwhile project, professional workmanship !! a pleasure to watch, and the time is really not an issue. Very informative. Thank you !!

That was an awsome demonstration of a lithium solar generator battery build, best I've seen!

Up to 5 million and counting. You make great videos. Thank you!!!

Well done video - concise, clear, to the point and of utmost importance....no crappy music!! Bravo!

This is probably the coolest thing I've seen on KZfaq in a while. Love it!

this is actually amazing information. Thanks for giving us your time and knowledge!

This is absolutely one of if not the most through videos I have ever seen. Your video editing skills are equally superb not to mention your knowledge of electricity and electronics. I would however like to mention one thing about batteries. Most people have no knowledge of what voltage is as opposed to current and the dangers that lie therein. When I was a young boy, and I am now 77 " electronics" for the most part did not even exist and the transistor was in the development stage. My knowledge of "Electricity" was very rudimentary. I learned a valuable lesson back then. I belonged to the Photo Club at our high school and back then the "Strobe" or flash unit used by photographers consisted of a battery and a device, mostly a capacitor bank to hold a very large chare to make the flash unit work when taking a picture. I was in love with all things electricity and electronics back then. One day I saw the battery for the strobe unit setting on a bench and thought how interesting it might be to see if one could actually get a shock off of this 250 VOLT battery about 7 inches square. So I decided to put a nail into each of the terminals on this 250 volt battery and touch them. At that moment I learned that 250 volts is in fact 250 volts no matter what the source and got the shock of my life which hurt like hell and threw me back and taught me a valuable lesson. 250 volts DC is for all intents and purposes just as dangerous as 250 volts from any other source such as a wall outlet or what have you. AC or DC at those voltages can and have killed many people. So what is the moral of this story?? Batteries can store a tremendous amount of energy limited only by the size of the batteries and of course their composition. These voltages can kill you and the higher the voltage the more danger even if it comes from a battery. Just because a battery looks small means nothing and herein lies the lesson. Know what you are dealing with. A basic understanding of Ohms Law and current flow as apposed to resistance is vital for survival. If your hands are wet or even moist and you come into contact with higher voltages you can get hurt seriously. What the average person does not know will kill them. Even laying a screw driver across a battery bank such as the one you have constructed or across say the terminals of a car battery can do serious damage. The amount of current available in a supply such as yours and or in a car battery can turn a screw driver red hot and burn up wires or in a worst case scenario blow up the battery and kill you. Electricity is not for the average simpleton that comes out of schools these days. Having a through understanding of the capability of such a supply as yours is vital. Serious burns, explosions, and fires dangers are always there waiting to kill you. You, my friend are a gentleman and a scholar and maybe even a good judge of Whiskey. Keep up the good work. Maybe perhaps a demonstration of what can happen might be a good video say turning wires into glowing things like what goes on in a toaster or such to drive the point home. A single car battery can burn your house down. Hell even a capacitor that is not stored properly can build a charge and kill someone. It has happened hundreds of time. It is sad however that the rest of the country is not up to your level of intelligence. Take Care and thank you for a most informative video. I enjoyed it immensely. Maximus has spoken.

THANK YOU FOR POSTING !!! ❤ You're GENIUS !!! and there's absolutely nothing wrong with anything! Editing is perfect! Build is perfect! Design is perfect and neat and the whole project is well thought out! I was an electrician for almost 40 years and you were talking way over my head! I APPLAUD YOU, SIR !!! And don't worry about video length! I could have took all that in for another hour! Pat yourself on the back...you did a great job! That's from Tennessee 🇺🇸

This is probably one of the most informative and super cool videos I've watched on YT. The amount of knowledge transferred in this video is amazing, yet I will admit this is still a daunting task, however clearly doable. Thank you for sharing your knowledge. That's the true value of information when it can be converted to usable knowledge. Well done and I didn't mind the long video at all.

I found this video very professional and informative. The graphics and presentation are as good as the narration. Great work.

So neat. Great build and so perfectly made. Smart guy. Thanks for sharing

Well done. They aren’t too long if the content is valuable. Yours was

This is probably the coolest video I've ever seen. I seriously am thinking of building one. I really appreciate that you put links to the components.

This is a great invention! I know there will people who appreciate it.

Awesome build and you made it easy to follow along. I'm not sure I could build one at your cost due to you having components' already on hand, but I'd try to keep it less then the already built models. Thanks for a great video and the length was just fine for all the information given, keep up the great work.

Thanks for this humble and innovative presentation. As for the length, it was over too soon for me! Thanks for the detailed equipment list, smart move with the disclaimer and thanks for sparing us an overdrawn intro segment.

I have watched this video till the very end most enthusiastically even do I'll never going to build this... Great job buddy!

Outstanding vid... and it was the PERFECT length. Thank you!

Awesome. Good instructional with good audio and pace. I work in electronics, electrical and computer buildout. Good Job !
