    Yes electron bump with increase resistance, so you’d be better to use a copper tube not solid.. Due to the way electrons flow, a tube will hold more current with less resistance.

    So the electron flows around the copper sruface thru the air?

    Thanks for documenting and sharing your setup!

    i have a question about wires all batteries together with cause a spark or blow it up???

  5. #5 by SwindleFlu at March 19th, 2010

    Nice video, question about batteries do they all need to be the same size for a battery bank? I have 4 lawnmower batterys and 2 car batterys that still work, can they be wired together? Also if anyone knows about 12v Trickle chargers, can multiple one be clamped to the same battery or do they have to be put on seperate batteries?

    It has been clear and sunny all day, after Iread your post i ran my 500w leaf blower on the powerbright. The cable to the positive side on the terminal was getting really hot to the touch. So…..mabe if too much current was flowing it could melt the casing…? The batteries are sealed Absorbed glass mat (AGM) They are notsupposed to vent hydrogen gas with normal use.

    Sure, if you watch that episode of the Discovery channel show “The Colony”
    they scavenged 20-30 car batteries and hooked them together. The weaker ofthe batteries will bring down the others. Just don’t drain the batteries too much under 12V. Batteries I’ve learned like to be kept healthy if always charge. Run everything you can when the sun is shining. Use those batteries as a buffer. Always keep a volt meter on them.

    Is that charge controller the one that came with the harbor freight kit? The 24 volt option can help with some of the higher powered inverters I can scavenge from old computer server power backup systems.

    Nice…… thanks for showing us your setup!

    @pgm98387 cool who cares if ur power goes out on a sunny day lol

    it’d be nice to see the actual panels

    Electron flow towards the surface of a wire is only true for very high frequencies. That is why radar and microwave systems use wave guides. For normal house current solid wire is used.

    Our Small Wind Turbine kits have both wind and solar as a hybrid energy kit. Solar never charges at night or on cloudy days. Wind power kits are a great way to reduce or eliminate your home energy bill. Most people are going grid-tied and making the utility buy back the unused energy made from their windmills. Home wind power kits can be installed on a roof or in the yard of your home very easily. Small wind turbines are rapidly spreading across America combined with solar.

    I think you have a very good setup. My goal is to get to a point where I can keep a mini-fridge (no compressor) running 24×7 (my wife is diabetic and keeping insulin cold is VITAL to its life potency). I also want to be able to run an electric burner/skillet…for cooking/boiling water. beyond that…I can make due without some other stuf. Alternating essentials (tv, radio, lights, etc) will be doable with the right setup.

    Have the harbor freight or sunforce panels lost output power (watts/amps) since you’ve had them? I’m looking at getting either the harbor freight or sunforce system.

  16. #16 by PiercingKnight at August 26th, 2010

    Anyone can give me an advice on what battery to choose? If I have a 144 Watt panel what capacity battery should I choose? Let’s say that I want to store all day’s energy. What if I wanted to store energy from two days? I don’t know much about batteries, and how to understand those units (amps, or amp hours), can someone explain the math to me. Help would be greatly appreciated.
    P.S. Panel 36 Multi-Cryatalline Silicon 6×6 cells, 18v, 8amps.

    Drama Of The Gifted Child by Alice Miller on the side there, great book 🙂

    wonderful DIY tutorial

  19. #19 by Jthetinman at October 1st, 2010

    Great job! Maybe be a lil more neat though. Messy wires everywhere.

  20. #20 by FUBARPROTOCOL at October 6th, 2010

    Those battery rods are a bad idea! Very Dangerous with those exsposed rods. If something falls across them, you can butn your house down. You need a covered battery box with a vent to remove battery gases.

    @SwindleFlu your battery bank is only as good as your weakest battery! they should be all the same age and capacity! In a survival situation then get as many as you can, and just test often to find the weakest or shorted ones! Dont use new and old together! Yea it can work, but its not a good Idea! a 1 year old bat and a 5 yr old bat together will be taken down when the 5Y bat shits on you! Joe

  22. #22 by toobroke2fight at October 7th, 2010

    get the bag off the charge controller! it cant disipate heat without air flow! Mount it on the wall so its not being dripped on! That will drop the power of the CC if it overheats! PS how does that copper rod hold tight to the terminal of each battery? does the one battery have a hole in the top? looks like its bulging and has a hole in it???cross connect the bat bank! dont put one panel on one side or the other! pos on one side, neg on the other! puts load evenly! NO BAT CLIPS! wire is too smal

  23. #23 by toobroke2fight at October 7th, 2010

    your charging the end batteries of your battery bank and allowing your other batteries to “leach” off of them to charge! your not charging all the bats properly! If you want to split the power at both ends then put a pos and a neg on each end of the bank! ON OPPOSITE ENDS! one controller has a pos on one end and a neg on the other! look up cross connecting a bat bank! your overloading the end bats! Save the bats pse! they are a good choice! Joe

    I’ve since then changed this setup. Watch my more recent videos.

    @toobroke2fight THANKS:)
