How to go about setting up an off grid site.
Here I am going to explain what I believe is the cheapest way to set up a building off grid. This is going to be called the Off Grid Chicken Coop.
We have a 20' x 20' Chicken Coop we want to have power in, but it is a long way from the grid.... The best way to do it is an off grid system.
We are going to light this Chicken Coop up like a
church house and have enough power for you to have some tunes to
listen to when you are out there gathering eggs or whatever else
there may be to do in a Chicken Coop.
Now that we know the amount of draw we have we can go buy a very inexpensive inverter from a discount house that can handle 225 watts constant load, likely a 250/500 or a 300/600 watt inverter for less than 50 bucks....
Read the data supplied on the inverter and see how
many amps it draws at the rated output. This will help you
decide how long you could run this setup on one battery.
Also take a look at the no load amps.. That rating means how
much it draws while doing nothing. The way to avoid the no
load draw is when it is not in use unhook it or turn it off....
Some deep cycle batteries are rated in amp
hours... Lets say the battery you find is rated at 100 Amp
hours. Since you never want to drain a deep cycle battery down
below around 40% of its capacity you actually have 60 Amp hours of
The inverter is going to draw 8 amps at full output,
so divide 60 amp hours by 8 and you have 7.5 hours (meaning this
setup would run full out for seven and a half hours without any
charge input at all).
Next we need to consider how much the system will
not be in use and not drawing any amps at all.
Now how do we maintain this battery is the next step.
In my experience if you put 1 to 2 amps of charge into the battery for about 10 hours per day you should be able to maintain this system and use it rather moderately.
So for a setup like this you need to consider the
amount of wind you have on average to help figure the amount of
average charge you would be producing into your battery bank.
Chances are you will find that you can have a lot of down time or
charge time for most of the smaller remote systems like this one.
It is really that simple.
