  2. Why do you think Surrette batteries are the best? I am in Ventura CA and
    have solar panels already I just want to get rid of Edison and there smart
    meter.

  3. For best results use a 120 volt battery bank with a 120 volt DC to 120 AC
    inverter

  4. Ever hear about NiFe batteries (nickel-iron, aka Edison Battery) invented
    by Edison at the turn of the 20th century? Apparently not.

    Edison Storage Battery Co. started 1901 made NiFe batteries all the way
    through 1972. EXIDE bought out Edison Battery in 1972 and stopped making
    the batteries in 1975. Seventy years is a proven track record that it does
    last +20 years. Exide after all makes more money with lead acid batteries
    so why not shut down that part of their company that is less profitable..
    That “more money” comes from Exide’s customers, ie you and me, if we use
    them. Google any key words and read for yourself. Cheers.

  5. my batteries drain in minutes running a single 5 watt bulb any help to why

  6. Hi ,Can Deep Cycle Battery’s be kept safe in a bedroom / or would they
    need to be vented out side, I am trying to find away to help my farther
    replace all is stolen 600 watt solar set up which I know took him two years
    more to get everything he lives in UK ,I cant even find an inverter that
    will run 230 / 240 volt UK items,I spent hours on line looking can you give
    me any tips were to look battery’s to use

  8. I like your neat and organized setup! We’ve got a grid-tied system with
    12.5kw capacity, but max I’ve ever seen is just over 10kW, since the panels
    are at various angles relative to sun. The bummer is, the most efficient
    for grid-tied is the new micro-inverters, which crank out 240VAC right
    behind each solar panel. Makes the wiring much cheaper too and a bad cell
    doesn’t pull down the others. Problem is, if you want to also have power
    when the grid goes down (dugh!?), then you need to add some very fancy
    hardware. Basically a charge controller, which can also output a clean,
    stable, 60Hz, 240AC to trick the micro inverters into coming on. Now all
    that power has to go somewhere, so you better have some big batteries and
    even a heater/hotwater load to take the rest when the batteries are full.
    I’ll be back… to see more of what you’ve got going there…

  9. Battery power

  10. Man your system look like it cost 20 grand

  11. OB, what is your background? you seem to have ninja skills in everything

  12. It seems this person is doing the best he can.The batterys for the job are
    Trojan/6volt golf cart batterys.These batterys come in a range of reserve
    amp hours.
    The thing is getting a solar panel that can charge two 6 volt batterys
    wired in sieries producing 12 volts.
    You don’t want gell cell baterys and Exide batterys are a piece of junk.
    Most aplications of this nature require a prime mover.

  13. Hi and thanks for posting your video, I will be purchasing a solar system,
    The kit will produce an average of 1200 Watt Hours (Wh) or 101 Amp Hours
    (Ah) of charge per day. The Inverter is 1500W at 12V. I am confused, is
    this system compatible with two 6v batteries or should I purchase one 12v
    battery?

    By nasbahh on Nov 24, 2014

  14. Marine jell batteries are no good, Or any battery with a cranking amps. the
    reason 6volt golf cart batteries are really good is the “Hour Amp Draw”
    Which is what this guy states! Although i would like to know what way you
    have them hooked up, You throwing the power out 6v/12v/12v/24v??? Nice
    helpful video ; }

  15. 60X30%=18+60=78 amps returned for 60 used.

  16. Nice setup. just want to asked 6 pcs of solar panel (17.20 Vmp) (21.60
    Voc) (8.14 Imp ) ( 9.13 Isc ) and ( 140 watt ( Pmax ) in series
    configuration to charged controller of ( 60 Amps ) ( 145V maximum solar
    input voltage ) and ( 60-115 vdc pv array mppt voltage range ). my
    question is. the mppt charged controller can handle this 6 pcs of solar
    array, and do no harm to charged controller? Thanks every one.

  18. your maths with the recharge rate was wrong. 30% 0f 60 isn’t 30.

  19. I heard you say you’re on the Outer Banks. I am 6 hours away, but getting
    ready to build myself a solar backup system for the essentials
    (refrigerator, freezer, some lighting). Any thoughts before I go shopping
    for parts?

  20. ALL of these batteries are not as good as you can get for the money.
    They’re either lead-acid or gel-cell. All of them have a VERY limited
    lifespan of 5-10 years if used correctly and properly maintained. Where are
    the Nickel-Iron batteries, Iron-Edison batteries have a 10 year guarantee
    and some of the original Edison Electric Co. Nickel Iron batteries are
    still working (some at almost 85% capacity) 100 years later! Why spend a
    ton of money on something that should last at least 20 years but only lasts
    5-10 years. The lead-acid batteries are 19th century technology, why are we
    still using it? Ni-Fe batteries can be discharged MUCH MORE without
    damaging them and reducing their lifespan. They also have better
    charge/discharge capabilities, and if properly maintained should last your
    LIFETIME!

  21. Thanks this was very helpful. I am a solar enthusiast with zero knowledge.
    So I am learning from scratch and I pretty much understood everything you
    said.

  22. What about RV batteries? In an rv with wind?

    By Arulin E on Nov 25, 2014

  23. go for cdr-king solar panel much cheaper than other brands.

    By Asmodel on Nov 25, 2014

  24. Wow, I do love your setup. Thanks for sharing your inside. If possible, can
    you tell me how do I know how many batteries and how many solar panels do I
    need to run one fridge, one freezer, and some household lights. Thank you
    in advance. Dino

  25. Thanks for your work and sharing the information!
    Great video!

  26. I’m rather surprised that the battery are not lasting beyond 4 to 5 years
    before they are replaced. Sounds like the batteries are building up a layer
    of sulfate (sulfation,) which is actually VERY easy and CHEAP to solve. Try
    adding a teaspoon of Epson salt to EACH cell INSIDE of the battery, then
    charge them to a 14V charge for a couple of hours . After checking and
    validating the voltage is holding at 12.5V or higher for at least an hour
    after being removed from the panels before hooking them up to the inverter
    (I assume you are using a grid-tie vrs. a simple isolated grid lije when
    camping.)

    The desulfation may (the first few times) cause the battery to get a bit
    warm, but so long as the caps do NOT pop up and the acid starts to leak out
    (by charging higher volts at a lower amp) it should restore an old battery
    to it’s virtually ‘NEW’ ability to charge and RETAIN the charge.

    I’ve got cheap batteries I bought at Walmart that are running just as good
    as the day I bought them. Heck the system works so well I’ve had the power
    co ‘question’ me, and wanted to come out and ‘review’ things…. I think
    they are hust frustrated because they have been paying ME for the surplus
    power now.

    Hehehe…

    God Bless & Semper Fi!
