How to Wire an Off-Grid Solar Battery Bank at 48V for most efficiency.

Installation of 16 x 6V Deep Cycle “L-16” batteries for an off grid solar power system. This is two series of 8 6V batteries wired in parallel to get a 48 Vo…

    Sorry to blow your breaker there KUHRD but the Voltage of these batteries
    is not the big problem to consider. Yes they may be only 6 Volts each and
    he may only be able to contact two at a time, however as he wires them
    together it becomes an issue of Amperage that is the risk. These deep cycle
    batteries may be of a lower voltage but they have GREAT Amperage and that’s
    where the horse power lives so to speak. Hence why a measly 48 Volt system
    can melt his tool in his hand. Never assume low voltage cant kill you dude.

    This topic wasn’t covered, but why would you want to go from 12v which most
    do when starting out to 24v and then to 48v? When you add them all up it
    comes out equal. Does going higher voltage charge your batteries faster
    and pushes more amps into your batteries over a 12v system? I am currently
    running 12v throughout and thinking of bumping it up to 24 but I would like
    an explanation first before I go out a buy a 24 or 48 volt power inverter.

    Are you kidding me!! You have a very nice, clean , set up! That’s for
    sure!! I have basically the same thing but 12v but this is a video of Felix
    that’s all

    Thank you for posting brother

    Nice set up you have there and keep up the good work. Spot on about the
    plasma potential. Arc flash, be it AC or DC will produce Plasma and if you
    are in close proximity can receive severe burns and be sprayed with molten
    metal. A couple things I highly recommend are face shield,insulating rubber
    gloves and protective clothing that will not melt to your skin. The general
    public has the misconception that batteries cannot do any harm. This can
    be a fatal mistake unfortunately for some.

    I wonder if you can help me with my situation.
    I have a 10,500 watt off grid solar system with of course generator back up
    and a 24 battery, 6volt battery bank. I have 24 new batteries coming in
    soon and I want to make sure they are wired correctly with series/parallel
    configuration. Could you possibly make a diagram of how they should be
    wired correctly using Series/Parallel wiring making a 48 volt battery bank.
    Please send e-mail to:… chris@tampabay.rr.com….and thanking you in
    advance for your help.

    Smart Idea protecting your tool from electrical shock. I have to remember
    this. Thanks

    Lol wtf. 1:32
    Seriously do you even know what plasma is. So you think your tool will turn
    to plasma within your hand if it touches a positive and negative terminal
    on your battery?
    You seem like one of those people who thinks they are really smart and know
    everything and everyone else doesn’t know what they are doing but in
    reality are wrong most of the time.

    Just like some guy at school I remember that thought he was really smart
    and said some picture was an obelisk and I was like WTF no it isn’t and he
    said oh it’s actually the artists interpretation of an obelisk then. I was
    like how can you have an interpretation on something that is already known
    and exists. lol. Artistic interpretations are used for things that no ones
    knows what they would really look like. For example an alien or an
    interpretation of the afterlife or some crap. You can’t have your own
    interpretation of something known like draw a circle and claim that’s your
    own interpretation of the shape of the African continent. That wouldn’t be
    called an interpretation that would be just called insanity. Hey lets draw
    a triangle and claim that’s our interpretation of a circle. lol

    I enjoyed the video but I had several questions. Why 48v? It seems to me
    that no matter how many series you put into system that the actual input to
    the inverter remains the same as if you had all parallels. Input is not
    changes. The lower wiring cost is academic for eight batteries, very
    little price differences even though higher amps require larger copper
    connectors. So please explain your efficiency and lower wiring cost basis.
    Second question is on battery choice. Why not use AGM batteries since the
    marginal cost is offset by efficiency for charge and discharge times,
    better tolerences for daily temperature and for vibrations. And the most
    important reason – much safer due to not having hydrogen gas dangers. So
    two questions; why 48v and why not AGMs. Thank you.

    how many panels do i need to run a house that use 500kWh a month

  11. Derf2258 says:

    Everything’s good except the string interconnects, you should have two on
    each end the same length hooked together to your cables going to your
    inverter(s). This will better balance your bank.

    What if you want to run a a 24 volt fridge off the 48 volt system how do
    you do that >???

    Or 12 volt lighting ?

  14. Mohab awadallah says:

    thanks for a good video
    i just want to ask what if i have 12v batteries instead of 6 v to make a
    battery bank like yours?
    will that help me to let the battery lasts longer?

    in conclusive video

  16. jerry arnold says:

    using liquid dip is much better…

  17. jason cassell says:

    You can get a step down transformer to take your 48v down to 24 or 12

  18. Jon Phillips says:

    So many people do not know what they are talking about when the explain
    their own ideas on battery banks, but I am happy to see that you really
    know your stuff. Thanks for the video man, its good to see you taking so
    much time about setting up your batteries correctly.

    hey cool set up. i only have 5 battery’s at the moment. check out my stuff
    and please subscribe :D

  21. John Rogers says:

    This is an afterthought for you, I worked for Exide Battery and they used
    copper straps on threaded lugs that gave a positive connection and you
    could get consistent spacing.

  22. Solar Power Videos says:

    Hey, I totally understand, I wish I had better video of it… the reason
    being is that it was just me filming and was my first attempt at video
    taping it.. I’ll get better footage and post a new version. Thanks for
    watching. check my newer videos out, they are done better.

  23. Solar Power Videos says:

    I know, those first videos I did were horrible, I didnt record them the
    right direction on my iphone and didnt get enough footage. Sorry about
    that. I am getting better, check out my latest vids.. Thanks for watching!

  24. ejemm says:

    Hi, really nice setup!! What gauge wire are you using within the bank?

  25. Jake Bartley says:

    What’s the typical recharge time to fully recharged?
