    After having a friend ask several questions regarding a solar generator project he was working on, I decided this would be a good opportunity to build my own solar generator and fully document the process. The total build came out to around $641. This video provides an in-depth look at the process involved in collecting and assembling the battery pack along with the choice of components and some testing.

      Awesome. Any Diagram Plan for this project, please?

    4. John Doe

      I was wondering how much the materials cost for this project.

      1. John Doe

        @LithiumSolarThat's not what I meant. I mean including the stuff he already had from other projects such as the solar panels and the inverter.

      2. LithiumSolar

        $650. The cost is in the title of the video lol :-)

      Nice job! At 3.5M views, you could have sold advertising space where the name of the tool box is :-) Great video!!

      1. LithiumSolar

        I had no idea this was going to happen lol... And thank you :)

    7. Remi Caron

      Great video and perfect delivery. Not too tideous but all the critical steps where shown. AWESOME!

    8. Nemo D333

      Don't worry about the length, it's very interesting to listen to you.

    9. 123 Up And Adam, Inc

      Great job, looks like a high-quality product. Do you make any to sell?

      1. LithiumSolar

        Thanks. No, I don't sell them unfortunately.

    10. AllRightsReservedWithout PrejudiceUCC1-308

      This video is one of the best I have seen here on youtube. No noise on the backround, no loud music and very clearly presented.

    11. Aman Aman

      Now you can work on, how to make small but power full battery.

    12. Laber Bla

      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!

      Excellent work.

    15. White Night Demon

      why do u have to wear gloves when taking apart the batteries?

      1. White Night Demon

        @LithiumSolar oh

      2. LithiumSolar

        The broken plastic and metal is very sharp and easy to accidentally cut fingers.

    16. Gareth Bruce

      Excellent video, very informative and well presented

    17. thirstygerry

      One of the best battery pack instruction videos I've seen. Thanks and keep it up!

      Hardest part of the build.... opening 130 battery packs :)

    26. Fortino Gutierrez

      I desperately wish I could do this.

    27. lond river

      MAn, make them and sell them, is too much for non techy minds like mine.

    28. wrdrvr

      Learning: If instead you just wired two car batteries instead, you could get 24v out and it would last longer but be a lot larger and heavier, right ?

      1. wrdrvr

        @LithiumSolar great, thanks for your reply!

      2. LithiumSolar

        Car batteries are designed to provide a big rush of instantaneous current to start the engine. They won't last very long if you start deep-cycling them. Additionally, flooded batteries (car batteries) produce highly explosive hydrogen gas while charging.

    29. Robert V

      Why were you excited about the 7A vacuum drawing 70A from the battery? It seems like it would be better if it drew only 7A from the batter?

      1. LithiumSolar

        I'm not sure I understand your question. Inductive loads have a high inrush current. I measured that inrush current to be 70A at 48VDC for my shopvac. That's exciting.

    30. Gustav Gans

      nice job man

    31. BlitzBenedikt 15

      This video was helpfull

    32. Thomas Luggiero

      Awesome!

    33. M!ke_y M

      Interesting.

    34. Max Que

      Would you be able to hook up a 12v, 100w panel to this system and charge successfully (albeit slowly)?

    35. 2H80vids

      Not a criticism at all, just curious: You kept things pretty neat but I was going to suggest drilling through the red plastic on the lid, to allow neater, more secure routing of some of the wiring. I then noticed that you 𝒉𝒂𝒅 done that, but only with 𝒐𝒏𝒆 wire. Any special reason, or just a pain to drill? Another thing I considered: depending on how/where it gets used, would it be worth putting wheels/castors on the bottom? It must be pretty heavy. A very interesting project, filmed in an easy-to-watch style and well-explained.👍👌😁 Cheers for now, Dougie.

    36. joebob3719

      Hey, how heavy is the kit when finished?

      1. LithiumSolar

        It weighs 57lbs

    37. Ronald Carter

      Why was there one cell with its polarity opposite of the rest of the row? Shows up at 6:16. Near the bottom of the pack, 6th column from left to right.

      1. Ronald Carter

        @LithiumSolar np. I was making sure I didnt miss anything on the setup. Thanks for the build!

      2. LithiumSolar

        It was a mistake.

    38. Sean Kelly

      That is the coolest bit of expertise. That box is badass. And I love the presentation. Also, we’re building a food truck and need layered power and propane systems. This looks perfect for running blenders and lights and even maybe refrigeration.

    39. rapid

      This guy is off his head

      1. rapid

        In a good way 🙂

      2. LithiumSolar

        ok

    40. jamesATgmailDOTcom

      Excellent video. Almost all of the information I was hoping to get out of it. Thank you so much for making such awesome content. Do you know if this would be able to charge a ford fusion energi with the standard travel charger? I live in texas, so maximum solar input would not be an issue.

    41. mickeycab1

      Nice job 🤙

    42. ridefast0

      Great project - and did anybody else spot the backwards cell at 6:15 ? Must have corrected it before final welding.

    43. Mnementh2230

      This is flippin' awesome. Makes me want to make something a little bigger as basically my own Powerwall kind of thing.

    44. Eric Clay

      Nice job

    45. sramctc

      A very decent self-made generator, Great!!!

    46. Y English

      One of the most interesting videos I have seen on youtube. Thanks!

    47. Richard

      I'm not that technically minded. Though the step by step your video goes through is one of the best explained and shown I have seen on youtube. ( adaptable information ) I do believe - given the opportunity. I could follow your steps and guidance to build this or a smaller one. Thank you very much for making this video.

    48. Keyon Rich

      Great video. Are you interested in selling this unit?

    49. Chris Eguires

      Very cool video! I do have a question though, any concerns about balancing the batteries?

    50. Uncle M

      So how long would this power a standard size kitchen fridge, a furnace and perhaps some lighting in two to three rooms, a small radio, two cell phones charging and wifi/router setup? Can you use the voltage/current while its charging or would it be better just to use the panels in the daytime and generator at night? PS- havent read the QA yet, will check that soon.

    51. Victor Padilla

      Love this video. Very informative. Thank you

    52. Lorena Barba

      This video is so inspiring and the way you explain things looks easy.

    53. Trent Richards

      Very interesting stuff!

    54. David Chang

      Really too many batteries to charge and maintain. Good job mate ! 👍

    55. James Smith

      Great video. Many thanks for explaining it all so well. 👍👍👍

    56. Chris Cattelino

      Put wheels on it.

    57. Andu Raaru

      nice!

    58. François Morin

      Wow man, nice work!

    59. Big Diesel

      You're a smart man, my only comment is it's a little monotone and dry, but that's the subject material as well, I suppose. But you got me to subscribe because I value a smart mind over the dribble that is KGup. Keep it up!

    60. Jay Wendorf

      Good video. With all the detail you provided, I was sort of expecting a link to an actual wiring diagram. But that's just me wanting to be spoon fed...

    61. rastitutka

      great video!

    62. ckolosky

      I never knew I wanted to learn more about this until today. Thanks.

    63. cyan clay

      @DIYPINOY

    64. Amr Elkassas

      Excuse me for my leak of knowledge but what if the solar panels over charged the battery and wondering if this work on 220v and how much time it takes to recharge batteries , thank you.

      1. Amr Elkassas

        @LithiumSolar Thanks

      2. LithiumSolar

        There are 2 levels of protection to prevent overcharging. The charge controller will stop charging once the batteries reached full-charge voltage. If that failed for some reason, the BMS on the battery would shut the battery down. Yes, it can work on 220V as well - just need to pick a different inverter that suits your needs :)

    65. Jessy Nadeau

      Wow! now i feel i am a total idiot! THank for this video!

    66. BEYENMEDİYSEN İZLEME

      Harika yaptın tebrikler.

    67. Evan Frederick

      forbidden vape.

      1. LithiumSolar

        These are not vaping batteries, very dangerous...!

    68. Andre Porter

      What do you use to test large quantities of 18650 batteries? I think I want to build a solar battery array but my idea is to have it all on a utility wagon, solar panels and all. Maybe even have a water and wind turbines as well. An AIO off grid emergency power service. 😀

    69. Andre Porter

      The Amp rating of XT plugs is right in the name of the plugs. XT30= 30a, XT60= 60a, and XT90=90a. If you need a connection to handle higher amps I recommend looking into industrial supply.

    70. gary nunyabissness

      well i dont have the money or brains but i learned alot so ty vrymuch i feel smarter just watchin ty for ur time peace

      1. gary nunyabissness

        liked and subed keep it up

    71. dvfreelancer

      Super interesting but it seems mind-bendingly difficult. Probably because I have no experience wiring battery packs.

    72. atvking535

      Nice video! One thing I noticed though.... Shouldn't you have more nickel strip on your series connections (like every cell instead of every other) as that's where the most current flows through?

    73. Anuja Nimesh

      How do you test their capacity ?

    74. Oleg Medved

      если ящик будет белым,то от солнечных лучей не нагреется,или накрыть белым пластом,защищая от нагрева.Так же спасёт тень(импровизированный навес)

    75. Trigger Happy

      Nice job mate!!!

    76. Evian Pengel

      if i make this with car batterys how many batterys should i put ? and should i seri or parralel do it . probably both with a 48v dc ? and how much amp battery ?

      1. LithiumSolar

        If you make this with car batteries, keep in mind those produce highly explosive hydrogen gas while charging. Do not charge indoors...

    77. Robert Szabo

      Amazing work, quite entertaining and informative.

    78. Sergiosaukka

      Hi Bro where did u buy the metal bladers and plastic holders?

    79. Torrential Rain

      How many times can I charge my phone on this? Would you recommend I put it on a trolly to play Pokemon Go

    80. GHOST5663

      Brilliant video and absolutely reinforces my decision to stay away from electric voodoo magic.

    81. George M

      Can someone explain why the lights dim while using the inverter vs the power grid?

      1. LithiumSolar

        The spot welder is essentially creating an instantaneous short circuit for a split second. The grid can handle the instantaneous current required much better than an inverter can.

    82. Steve Shearer

      Excellent video, thank you!

    83. AbstrusoTV

      wow this seems huge work for lithium batteries wth a limited cycle live

    84. bravojr

      Practical question. Compared to 8 t105's in 2 banks of 4 aka a 24 V system. How good is this? In said 24 V system is 24.6 the lowest voltage that you should discharge the batteries at of the t105 variety? Compared to this 48 V system what is the Lowest Voltage you should discharge this system to?

    85. cait kern

      Could you do a video on how you wired everything individually in the box? I get pretty lost at that part, it would be nice to see how you did everything step to step

    86. Ryan Ryan

      Boat shrink wrap

    87. Chris Lewis

      I liked the build, only thing that bugged me is the wire mess.... I have OCD when it comes to wiring/cabling. Gotta be neatly bundled and zip tied.

    88. Ramadlan Badar Mahangkoso

      i want one

    89. spartee101

      That was awesome, love the detail!

    90. Mekayl Krauss

      Does MAH rating matter on the 18650's? Just for reference, what is the rating on your batteries?

    91. Seth Apex

      I probably would need about 3 of these.

    92. Grumpy Cat

      Would like to see a full build of this.

    93. Panic The Scholar Knight.

      Can you solder those strips? I know it takes longer but I prefer soldering them.

    94. pageau1987

      Great video I would suggest using some marine grade flux when attempting to solder as the joints you made appear to have not cured properly. Try the marine grade flux and you will never go back.

    95. Monty Daniels

      Thank you. It's because of men like you the cost of the Lithium Ion Batteries are dropping in price. Soon they'll be as cheap, if not cheaper than Lead Cell's... I've probably recycled about 20-30 backup batteries from scrap gateways & such. Instead I should have been collecting them and researched where to start finding more or buying them. They certainly help make a persons mind up with not using older Lead Cell Batteries..... Great video, you are one smart guy. I subscribed too... Thank you for posting it.... MD........

    96. Putu Widiarsa

      I think you should mass produces these sir. They packed very solid surely will hit the market.

    97. Ernst James

      Shiddd... Video should have been longerrrrr. Great job buddy👍

    98. ricky tirado

      Very excellent,,, I hope you can teach here in the phillipines,, more of these,, thanks

    99. King Meshiah Alfred Bruner

      I personally prefer the use of either Ni-Cad or Lead Acid batteries as they do not run the risk of self ignighting or exploding. Yes they will explode if you cause a spark at the time of charging due to the Hydrogen gas produced by them. But it is not at all like the deadly fires and explosions caused by hot Li-Ion batteries. Also because I am totally immune to all types of acids (the real types not the drug). I do not want to do it my easiest way to many people get harmed if I call down the lightning which am also immune to as I tend to absorb to much of it and then I am a danger to others around me. Yes, I am one of those kind who destroy the lightning generators and electric fencers by absorbing more energy than they were made to endure even 120 volts DC is a tricle to me.

    100. Mark Selby

      I can't believe you had all those 18650 batteries in a box like that without any of them venting 😳
