Off Grid Air Conditioning A Sucess You Dont Need An Expensive System

For full details please read my blog post:

Ok, a full day and a night of testing the solar powered air conditioning system proves that it can and does work. My stuff costs about $2,000. You may pay a bit more depending on where you look.

In this video I show you where to get solar panels as low as 50 cents per watt. Yes, it is true. You may find that after shipping its $1 per watt. That is cheap and good. Its still cheaper than the full retails of $5 to $10 per watt.

My solar panels are off craigslist at 50 cents per watt. 800 watts = $400

My charge controller retails for about 500

The batteries are about 100 each = $600

The inverter retails for about 500 but you can get a tiger claw pure sine wave inverter off amazon for about $179. I read lots of good reviews about them.

Check craigslist for second hand or discounted, scratched or dented solar panels.

Check sunelec.com for low priced solar panels.

The charge controller is an mppt type tristar controller from

    I mounted a “double pulley”(junk yard $3) to my RV air condition compressor
    and mounted a 12V electric motor to run off the battery bank. That way I
    can run the RV gas engine to run the AC and charge the bats, run the
    generator to run the AC and charge the bats, use the solar panels to charge
    the batts and run the AC. If you have a good breeze get a windmill to back
    up during the night hours your solar.

    Just FYI, the reason the power consumption on the AC unit goes up in the
    first few minutes of operation has to do with the head pressure on the
    compressor. As the temperature on the high side of the system goes up, so
    does the pressure difference across the compressor, and thus its power
    consumption.

    So do you no longer have a job in the developed world, just spend your days
    surviving, getting basic needs met? Did you have to pay anything for the
    land?

    Consider using a small car compressor, just need a small motor and fan belt
    to spin the compressor then you are using 12V to activate the compressor
    with only a small amount of power for the small motor (12V or 120V), at
    this cost for the power stations, you can build one for each room and only
    use them when you are using that room. Just a consideration…

    You don’t say that you are running a refrigerator or freezer. I have never
    seen a day or night that I wasn’t happy with the large soap bar sized
    freeze cubes tucked under my armpits or behind my knees, between the small
    of my back and my belt, when sitting or under my feet with or a cold damp
    wash cloth from the fridge behind my neck with a small fan on me. But I
    don’t live in the NorthWest. On very hot days I will use them 4-5 times
    when I sit down and use several of them at time. You can use them in the
    car as well and leave your windows open.Just take a few along with you in a
    small cooler with ice. The cubes lower your entire body temp by 1-3 degrees
    and usually are only needed 15-30 minutes at a time. I prefer it to living
    enclosed with AC. I keep a dozen of them in the freezer during the summer.
    They take up very little space and I could get by with just 4 and a 16in
    fan.

      And, if you recycle the water that dribbles down from your armpits due to
      the melting ice cubes, you can refill the ice cube trays several times.
      That’s gotta’ save at least a nickel too.

    AMPS X VOLTS = WATTS

    430 WATTS WITH 120 VOLTS IS LESS THAN 4 AMPS
    430 WATTS WITH 12 VOLTS IS ABOUT 35 AMPS
    A 120 WATT LIGHT BULB USING 120 VOLTS WILL PULL 1 AMP
    AN AC COMPRESSOR PULLS LOCKED ROTOR AMPS TO START WHICH IS SEVERAL TIMES
    THE NORMAL RUNNING AMPS, A LARGE CURRENT DRAW BUT FOR VERY SHORT DURATION.
    i USED SIX 6 VOLT GOLF CART BATTERIES WIRED AS THREE 12 VOLT BATTTERIES
    THAT AC UNIT IS 5000 BTU’S

    so in your experiments how many aH is your battery bank and how many watts
    of your solar panels to charge that battery bank, and the value of your
    inverter, in order to operate your air con , tv and lights, is you air con
    is a 12 volts operated? or straight from your inverter?
