Great and cheap OFF GRID SOLAR BASICS BOOK written by the great Joe O’Connor:

Understand exactly how much power is stored in your batteries and how much of that you can use on a daily basis. This video also covers how power gets from your solar panels to your batteries and finally to your appliances. You will learn how to size your solar system according to how much power consumption you expect to have.

    good explanation. Makes me cringe though watching you sit next to lead acid batteries that are in equalization mode without eye protection.

    I plan to go with lithium

    I was ended up saving from expending money on a brand new vehicle battery when I heard about the reconditioning plan [ check Details Here>>> ], so I tried it to recondition my old vehicle battery! I wasn't expecting it to be so easy. That already saved me over $ 100 and there are so many some other batteries.

    WOW! You jump from topic to topic with no demo? Example, HOW you connected your batteries? I mean "I" understand but I have a technical background. YOU need a WHITEBOARD where you show your battery connections AND your math. Sorry, I'm just saying… then to the 'specs' you specify? Sorry again but your words are much too confusing! I won't give you a thumbs-down, but please redo this video soon… others may not be so kind.

    Excellent video. Thank you very much for making this. I can see by the comments that most people do not know about "deep cycle" batteries or the difference between a marine battery and a regular car battery. They also do not understand why you would want either a 24-volt or 48-volt system. If you could add some "Battery Basics" along with how DC appliances work, you may have the perfect video.

    So if you want solar panels on your roof to power your house you got to have a bunch of fucking car battery's in your roof?

    I recently got the EZ Battery Reconditioning program and just reconditioned two car batteries. The guides were very easy to follow [Check Details Here==> ]. I wish I would have found this years ago! Thanks!

  13. Christofer Steger says:

    Don't you recharge battery 130%. So if you use 3000Wh you must charge 4000Wh ?

    [Awesome Plan Here >>> ] It has just right information regarding solar electricity- its fundamental and how to size and install a system. Anyone with a little technical background can understand and follow easily. It illustrates real world solar electric design.

  18. Tracy Douglas says:

    The Ez Battery Reconditioning program is a digital book (ebook) which guides you through the process of reconditioning many types of batteries [Check Details Here==> ]. My first impressions were good. I must say there is a lot of information here and even better it’s formatted in a way that makes it easy to read and follow.
