    offgridesolarguy
    why do some people run modfied inverters and run tv fridge computers and get by some say you can,t. some say you can use
    modfied inverters with line filter and get by ,./ trying to get by on what i have? have your book& cd. i have 24volt panles but want to keep my 12 volt battery bank i have allready the 12 volt inverters what do u say thanks

  2. I bought excellent handbook from Inplix website. Just google inplix and start your journey to better life

    Go to Inplix if you'd like to build it yourself.

    Very clean setup.
    Keep on the good work

  5. i am working on getting off grid.. right now i have 5 panels on my roof, 100 watts, 12 volts, 6 amps each. i have now 5 panels, 12 volts, 100 watts, 6 amps each, and am going to a 12 volt battery bank.. i burned up two sets of batteries in less than a year.. first ones were 3 marine batteries, the other two are what i have now is two group 8 d batteries. one thing i learned is that if the battery says anywhere on it cca, it is a cold cranking amp battery and wont last long, so now by mid november i plan to get golf cart batteries.. not sure yet if i will get 12 volt batteries, or 6 volt batteries and pair them up to make 12 volts and have 4 pairs of them.. i would want my battery bank to last more than 5 years… not go through batteries every few months…

  6. 23 volts is pretty low i try not to take mine below 24.5

  7. Current is hard to move.  Higher voltage = smaller current.  Batteries on the other hand can only accept a certain voltage; in this case 24 volts, therefore the controller regulates the voltage "down" to what the batteries can handle.  (12, 24, etc)

    Very clear! Good job!

    Is it worth it to live off the grid just so you can grow some weed? Jesus, how much are you drinking during those long winters? Does you boyfriend get sick of yanking your rod after a while? Go nuclear!

  10. baileyslip says:

    I also wanted to add "Great Job" explaining your set up.;and thank you.I gotta ask what are the batteries for? What do they do and why do we need them Thanks Linda from Ga.

  11. I am not sure what you are talking about when you say you have two boxes that regulate the power going into the battery bank?  You seem to have the battery power going into that Xantrax box, then over to the charge controller and on to the battery, but additionally the Xantrax box supplies power to the inverter?  Is it doing some kind of isolation?  Very confusing?

  12. outbackeddie says:

    Great video. I especially like the explanation of battery wiring. Very helpful. Thanks for the information.

  13. Duane C says:

    The whole point of the high voltage from the panels and wind turbine is that you can use a thinner wire to transfer the energy. other wise you would need thicker / heavier cables running into your boxes. The higher the current the thicker the cable needs to be.

  14. to help prevent corrosion on your terminals, look into Eezox. Great videos. If I had a house, I would definitely use your videos to build a solar system. Unfortunately, I live in a Condo. Keep it up sir!!! This stuff is awesome.  

  15. jimbolecat says:

    good video's clear information. can i ask you what your system cost? panels, charge controller and batteries? would you change anything if you had to buy again?

  16. Aguila59 says:

    Sir, you do not have enough pvs to charge your batteries, unless you do not draw any power from it.

  17. CLOISERIE says:

    HELLO, ARE WE TALKING $10,000 FOR A SETUP LIKE YOURS ?, I'VE BEEN THINKING ABOUT PUTTING PHOTOVOLTAICS ON MY ROOF TO DROP MY ELECTRIC BILL DOWN TO $10.00 A MONTH.

  18. zenseivideo's comment is kinda hard to read…. basically, amps is what dictates the minimum size of your wires, and copper is expensive

  19. Whit Elfner says:

    Are you really selling systems?

    If you knew more about solar, you would understand what, "thastinger345" is saying. The total watt hours available from a battery bank is what's important. You could just use the same batteries just more in a string. If fact you invite uneven charging with out having a common connecting point for your strings of batteries, for equal distance in wiring resistance.

    Please learn more before you sell anyone anything!

  20. Very nice video!!

  21. Adam Cook says:

    I x I x R does not = 2 x I x R

  22. moo. says:

    You should seal your battery connections with liquid latex. $5 bottle of liquid electrical tape will help a lot. Looks good though!

  23. Why did you chose the 6v 350A Batteries? Why not 12v 700A Deep Cycle Marine batteries.? I need 100KW/day Avg power. Can I get that from a Solar system like yours or do I need a whole field of Solar Cells?

  24. I also try it…good site

  25. Bobby Hughes says:

    So I am looking at using solar on my homestead and I'm just in the planning phase for everything right now and I need some help with the math… Based on my electric bill I use on average about 1500wH's per month which is about 50wH's per day. So could I get by with may 250wH system? How do you figure all of that?

  26. you are correct, i know alot of people who think it is fake. Listen, i've been getting paid about $200 a week just selling energy. I took the idea and plan of here. you can also try it: ABOUTSOLARCELLS.COMXA.COM

  27. Its immaterial since we cannot go to 48V. The inverter is 24V input, and we cant move the larger batteries into our shed. So your point is moot. And our neighbor just retired 11 year old L-16's. It can be done.

  28. well if you went to 48V then you would only need 700Ah…pounds of battery is pounds of battery, just in how you configure them. I wish you luck in getting 7-10 years of life from parallel strings of L16s

  29. Good question. The panel wiring was much easier at 24V, as was the inverter wiring. But also if you go to one string, you have to get big batteries that will get to my desired 1400 Ah rating. To go one string I would have had to go with a 1400Ah 6V x 8, and those batteries are simply too heavy to get to my shed and then into the shed. The technology is advancing rapidly, so I hope to do that in the future, but will stick with 24V.

  30. why not go to a single series string 48V battery setup? Much easier to maintain equal battery charge that way.

  31. I just watched a video you posted last night, then went to power4patriots – I dont know what all the negativity is, its cheaper than a meal for a family at Olive Garden! OMW!! Some people what, Expect it to be FREE? Or Hollywood Grade? Its Info!! and btw You Do and INCREDIBLE JOB in this video explaining it very well!!! I tried to purchase the power4patriots package but after 3x's it kept saying their was a problem processing. I used to own a sign shop in TX, but now just do commercial grafx

  32. Zenseivideo says:

    High voltage is good, because P=U * I (Watts)
    Heatloss in wires= I^2 x R = I x I x R = 2 x I x R (Watts)
    R = Resistance in conducting material
    I = Amperage
    U = Voltage
    P = Power
    So we want to limit the current I (I=Amps), since it's the biggest factor of heat losses which can be prevented the easiest.

    Hope it helps people 🙂

  33. ejlarson249 says:

    Ok.. You claim you are not affiliated with power4patriots… But, I looked at 3 of your videos, and all 3 have a link to power4patriots in them. Where I come from that is called a lie.

    I know what you mean by turning folks away if it gets to be over kill. I think what you have is great as far as being off the grid system. I have family out west that have lived off the grid since the 70's but they have all the modern conveniences. They live off a gen set but at night it goes off before they go to bed. For me being a grid dweller it was fun like camping and it was more relaxing not having stuff going 24/7. I would someday love to be off the grid.

  35. A lot of people would say that is indeed science 🙂 I know how it works but don't want to get too technical, or people tune out.

  36. Hopefully about 7 years, some people get 10!

  37. egn83b says:

    Their is nothing scientific about dropping voltage from a high voltage. What you get is more current. Low voltage high current. High voltage hence the low current. Power lines use this method tell they get to the transformer where the transformer take the high voltage and drops it down and brings up the current. Look at the wires coming from your panels they are small low amperage battery bank high amperage. So what you have is a step down inverter transformer in your controller. Hope this helps
