The TLG-500 Wind
Understanding why the TLG-500 is your best choice for a wind generator.
A lot of people seem to be
asking the same type of questions about the TLG-500 wind generator. Many of
these questions are answered in different sections on the website but are
Most DC wind generator systems produce DC straight out of the unit. The problem with DC output is it is harder to get what you create into a battery bank. DC, meaning Direct Current means exactly that. The current travels in one direction and one direction only. Most people install their wind generator using affordable wiring. With smaller affordable wiring if you start out with 5 amps being created from the generator you probably only see about 1 amp going into your battery bank. Part of this problem can be addressed if you have plenty of money to spend on huge wiring. But lets face it, it is not cost effective to string out two 100 foot runs of 4 gauge wire, or to try to maximize your output some people buy 1/0 wire to run from the generator to your batteries. Even with wires that large you can still loose some amperage if the run is very long.
The TLG-500 drastically reduces the loss issue by not creating DC output from the unit. The TLG-500 produces AC output through 3 wires referred to as 3-phase AC. This 3-phase AC is transmitted through much smaller common wiring such as an extension cord available at most stores. The extension cord connects to the wind generator head on top of the tower, it then runs down the tower and goes to the location of your batteries. Once at the battery bank the 3 wires from the generator attach to a 3-phase bridge rectifier which converts the AC into useable DC voltage. The Rectifier has two outputs, one positive and one negative which only uses two short wires to pass the DC output directly to the battery bank through a fuse or breaker. With the only DC output in the circuit being the two short wires from the rectifier the loss of power is greatly minimized.
Over the years I have worked on several different brands of wind generators from battery charging systems to grid tie systems. I think I have seen about every type of failure that a unit can have. All of these types of failures I have had to repair I made sure was not in the TLG-500. Here are a few examples.
Most units in my opinion are
made with what seems to be planned maintenance. Who wants to climb
towers, or lower the unit in intervals to do maintenance? I sure
don't! I figure if it isn't broke don't mess with it, and a unit
shouldn't have to be touched if at all possible.
Most other units use either a single bearing in the front or two much smaller bearing than the TLG-500 has in it. Bearings are the only moving part inside the TLG-500 generator head. By using bearings that are oversized and way over rated for the duty they are expect to perform this will naturally increase the life of the bearings considerably. So there is another failure I omitted from the TLG-500. Now a good question could be; will the bearing ever fail? They probably will, but if it does happen it will be several years down the road.
Most other units that furl in
the wind to control the units output and reduce lateral thrust wind force on
the tower are mechanical moving parts. Anything that moves will wear
out in time. Most of these moving parts have to be greased as part of
the maintenance routine. What happens to grease when the wind blows
dust around, it fills up with dirt which causing vital moving parts to not move freely and
will cause them to
wear out much faster.
Some units suffered from over heating because of internal electrical circuits. While other units just don't seem to have a way to dissipate the heat. The TLG-500 has it windings on the outside edge of its aluminum alloy case. The aluminum case is then attached to the aluminum yaw assembly, so basically the whole assembly is a heat sink. With overheating strongly addressed yet another known failure was omitted from the TLG-500.
Others units use, wood, fibreglass, and carbon fiber resin blades as there source of extracting power from the wind. Part of this paragraph is simply my opinion as I know there are hardcore wood lovers out there. My issue with wood blades is the maintenance they require, and what seemed to me to be the never ending balancing routine. Carbon fiber resin blades sound like they would be tough, but the only carbon fiber blades I have held in my hands are not what I would call carbon fiber blades, more like carbon fiber floor sweepings mixed with plastics. In my opinion to make a good strong carbon fiber blade it would take actual sheets of the carbon fiber material and precisely mixed resin. To build a carbon fiber blade of any quality most people couldn't afford the materials or the labor to have one made. Fibreglass done right makes a good blade, but fibreglass has its issues such as it is temperature sensitive, and can only flex so many times before it too will break. I have had extremely good luck with the aluminium series rotors. So far even the ones that have been hit with debris in storms have not come apart. We power the TLG-500 with the extremely powerful 5-foot Boast Buster rotor, so the failures of wooden, carbon fiber, and Fiberglas blades does not exists on the TLG-500.
Several permanent magnet generator use brushes inside them to transfer power out of the unit. Brushes are a high failure item and require regular maintenance. The TLG-500 generator head is a true brush less design so there is another known failure that is omitted.
I could some up the failure issue by simply saying this. Everything I have ever had to repair on various brands of generator over the years I left out of the TLG-500.
Output of a wind generator is
one very confusing subject for most people. Most every unit on the
market today is rated by the industry standard Instantaneous Output rating.
This rating is confusing to say the very least. I have heard countless
times comments being made from people that have bought units rated this way
and they cannot understand how they say it puts out wattage in wind speed
where the blades aren't even turning yet. Instantaneous output is a combination of shorted
amperage times the open voltage of a generator at a given rpm, and in some
cases its a theoretical output. In theory it is accurate, but theories
only seem to work in a perfect world, and who really lives in a perfect
world. Now to add insult to injury there is also an even more
confusing output data called Kilowatt Hours per month. Again based on
the original Instantaneous Output which I admit does make a
unit look extremely impressive.
The TLG-500 is a large 10
1/2" diameter, 28 pound, multi-pole rotary flux unit. You could fit
several of the Brand X PMA's windings and magnetic cores inside the case of the TLG-500 head. The
units larger diameter provides it a large magnetic swept area to pass over
the multiple coils which makes the unit put out more power right from the
start. The multi-pole rotary flux design is extremely advanced in
comparison to other units.
I could sit here and tell you
that the TLG-500 unit is the best of the best, but then it is my unit and
most people would expect someone to blow their own horn. I know what
the unit can do, but I am letting the owners tell you what the unit will
really do. Would you rather hear me tell you it is the best choice for
you, or would you rather hear what owners are saying about it?

go on and on here but I think with the information this page offers along
with the comments from people that have invested their money in a
TLG-500, that I have provided enough information to allow you to make a decision
based on the knowledge of the differences between the units available to
you. There are
plenty more comments about the TLG-500 for you to view on the website.
Each and every one is positive about the way the unit is designed and
built to it satisfying output even in low winds.
