What's what in watts.
I get a lot of questions about watts, and what it
means. That is because wind generator manufacturers rate their
generators in watts, or the (make it sound better than it is) watt
What is the difference in watts and watt hours...... For example:
someone says (this is a 25 watt generator) most people would think;
How about this instead, (this is a 250 watt/h generator... Not
too bad eh??
So watch "watt" you are being fed. ;) (pun intended)
This page is not going to be a lesson in
electronics, its just going to be an explanation of wattage in
"amperage", a common term that makes more sense instead of a
bunch of wattage hoopla that makes things confusing and many times
Here is what most people don't understand when they
are looking at a generator system. They think they must have
lots of watts all the time.
So you know what I mean by that statement take this example:
If you were going to buy a battery charger for your car battery or
even a deep cycle battery for an RV would you go to the store and
buy a battery charger if it had a selectable output of either
24 or 120 watts of charge power?
I think it is safe to say that most people would say
"I think I need something bigger than that!"
I really doubt it... That is actually a standard 12 volt,
selectable, 2 or 10 amp battery charger like most people have in
their garage. They charge up every battery you put on them in
a matter of a few hours.
Since the battery charger says 2/10 amp on it that
makes it sound big enough to do the job therefore there are billions
of them in garages all around the world.
Since all the DC Permanent Magnet Motors we play
with are all rated in voltage and amps , and when we are
looking for a good motor to use as a generator we look for the
highest voltage & amperage rating at the lowest rpm.
So for the sake of keeping it simple when you are thinking about the
charge power you need for charging your battery (think amps)...
It will give you a general easy to understand base line to start
Now with this information in mind the TLG-500 puts out every bit of
what a standard 110 volt battery charger puts out and it does it in
winds of 20 mph and less, with much much more in higher winds which
would make it a good fit for about anybodies needs.
Summing it up you would have the amperage rating of 3.5 amps at about
10 mph and the full 10 plus amps at about 20 mph.
That sounds pretty good doesn't it? But wait, same 2 to 10
amps of output is only
24 to 120 watts of power......
Now I think you see what I mean about basing your information on
amperage rather than watts.
