Renogy 30 Amp PWM Charge Controller Regulator Off Grid for Battery Charging
 | Description The main advantage of Pulse Width Modulation (PWM) is that power loss in the switching devices is very low. When a switch is off, there is practically no current. When the device is on, there is almost no voltage drop across the switch. Power loss, being the product of voltage and current, is thus in both cases close to zero. PWM also works well with digital controls, which, because of their on/off nature, can easily set to the needed duty cycle. This solar system controller adopts | |

Your Questions About Wind Turbine Generators For Sale
Robert asks…
Which is the best DIY solar panel/wind turbine program? Real people only, please.?
I’ve been looking at all of the options for installing solar electricity systems online, and I’ve noticed that even the so-called review sites all seem to be part of a sales pitch….haven’t found a single, independent review of any of these products. Has anyone out there actually used any of these (Earth4Energy, HomemadeEnergy, etc.), and if so, how good are they?
admin answers:
If you have noticed that Earth4Energy is a scam (which it is), then you may be amused by my analysis of it at http://www.nlcpr.com/Deceptions6.html
If you want to build a wind turbine yourself (like a good engineer would), then get the following book:
Homebrew Wind Power
A HANDS-ON GUIDE TO HARNESSING THE WIND
Dan Bartmann & Dan Fink
Foreword by Mick Sagrillo
ISBN: 978-0-9819201-0-8
Published by Buckville Publications LLC
You can get this from www.otherpower.com This is a startlingly complete book and it has all the background theory you need too. They explain why, for example, you cant use a car alternator or something from a generator, and then proceed to build alternators from scratch. The references are compete — if you explore them and have the time to read, you will be right up there with the pioneers.
As for DIY solar, you can get the parts (panels, inverters, batteries, charge controllers) individually from many sources and make a system. It will not be cheap. You can’t make your own silicon cells, and probably aren’t up to designing the electronics, can’t make your own batteries etc.
My recommendation is this: Get the wind book. Look through the web sites of some of the better looking solar dealers, and if they seem to be “no bull” then e-mail them and tell them what you want. E.g. An entry level system, 80W panel, battery, inverter and charge controller so that you can make enough power for say, a small laptop. The good ones will be able to tell you what works together.
If you are thinking of a whole home solution, then you have a lot of reading to do. You need to switch to natural gas or propane (no electric heat, electric stove, electric hot water) and absolutely mininize the electrical load.
It would be nice to market a good DIY manual, but with a truthful title like “Generate power at home for more than you are paying now” or “With thirty thousand dollars in equipment, you too can avoid those monthly power bills” sales would be pathetic.
Have fun.
As for “real people” comment, when I see questions like this, I wonder if I am wasting my time because many of the questions are not real either. They are simply created by scammers so that they can add their scam replies and rate it best answer. I find this particilary galling when someone says, “this is for my science fair, and I am 14 years old” and all the answers are Earth4Energy scammers. Other times, I find my comments pasted on fake energy sites with links to pharmaceuticals. It is a mad world out there.

Your Questions About Wind Generators Ebay
Jenny asks…
How you hook up a volt/amp meter to a wind/hydro/solar generator?
I’m interested in having a combo volt/amp meter gauge set-up to monitor what my power generating source (such as hydro or solar or wind).
I would like to measure this before it reaches the charge controller. So if someone is at the generator source, they can see exactly what the generator is generating (for making tweaks).
Not quite sure how to do this.
I do have a inline watt meter that has one side that says “Source” and the other side says “LOAD” but I think it has to be hooked up in a circuit with a load.
My goal is to measure the generator by itself and not hooked up to anything. I know I can do this with voltage but not sure if this is possible for amps. I Heard I may need a shunt set-up to make this work?
Thanks in advance for your knowledge on making this work would be greatly appreciated. What I’m looking for is a wiring setup.
Thanks!
admin answers:
No probs, look on EBay for digital ammeters. They are cheap and some supply the shunt as well for less than a tenner.
Daniel asks…
Where can I find a Permanent Magnet Motor?
I am planning on building my own wind turbine on a smaller scale. I have been looking around at permanent magnet motors and would like to avoid spending the money on one off of Ebay. I’ve tried “googling” what appliances I could pull one of these out of but have had no luck. So if anyone knows of any appliances or shop machines that may have permanent magnet motors I would appreciate it.
admin answers:
Any DC motor is a permanent magnet motor. If you can get an old generator from an old vehicle (not an alternator) some motors are rated DC volts you can use these

Your Questions About Wind Turbine Technician Jobs
Maria asks…
Is a wind turbine technician a reliable career?
im looking at schools but am hesitant because i’ve been reading articles discussing wind turbines as a scam. and research that talks of wind turbines complete inefficiency. thoughts and advice?
admin answers:
Some for profit schools over estimate the number of jobs and how much they pay. But then, the number of guys who will climb a 200 ft tower with a tool belt is not that large.
Fortunately there is a demand for guys to crawl all over transformers and through switchgear, and you don’t have to climb any 200 ft towers. We pay $30 an hour.
What I could really use is more relay technicians who can create relay testing programs out of thin air.

Your Questions About Wind Turbine Generators For Home Use
Sandy asks…
Make electricity with steam at home?
This is probably a silly idea but I really like the idea of making my own electricity. I’ve thought about solar and wind but neither would really work for me. My wife & I will be building a new home in 9-10 years and I have a new idea…. We want to have one of those outdoor wood burning furnaces to heat the house. Is there such a thing as a small steam powered electric generator? If there is, maybe I could use some of the heat generated in the furnace to boil water, make steam and turn a small turbine to generate electricity. This way, I could heat my home in the winter and make my own electricity all year long just with wood. Just an idea (maybe a stupid one). If anyone has any info on this subject please share it with me. Thanx.
admin answers:
The killer here is efficiency. The efficiency of a steam turbine is only on the order of 30%. The equipment is pretty expensive too unless you go with some kind of home brew set up which can be dangerous. You would need to burn a lot of wood to make any serious amount of power. It would probably be cheaper to buy from the grid.
Chris asks…
How can I start a wind turbine Business and where is a good place to look for grants?
admin answers:
The energy efficiency sector will skyrocket the next few years, so good choice with that!
Wind farms are starting to pick up attention from the general populace due to the dwindling supplies of fossil fuels and their rising prices, which in turn contribute to the rising power expenses. The use of fossil fuels to generate electrical power is also unfriendly to the environment because of the pollutant nature of fossil fuels.
There are two reasons that people may want to invest in wind power. First, to save up on power expenses by relying fully or partially on wind turbines to derive electricity; Second, to become more environment friendly. No matter what the reasons may be, you can take advantage by setting up a wind power business.
A Good Location for Wind Farm Business
The first thing that you have to ask yourself when planning to engage in a wind power business is, Do I have the right place to harness the power of the wind? Household wind power systems do not need to worry about this since their power requirements are minimal, but to be able to feed houses you would need to produce a lot of electricity. The best place for this is a location where there is plenty of breeze to turn your windmills, like near the shorelines as well as high places.
You Need Windmills
Windmills or wind turbines are the driving force behind wind power systems. It is through these turbines that the wind is used to harness electricity by using the kinetic energy generated by their turning motion. The motion is initiated when wind is blowing the turbine panels. No matter if the wind blowing is a breeze or a gale, the motion will continue to harness kinetic energy and convert it into electrical energy.
Wind turbines used in a wind farm can either be commercially made or made at your own home. Buying commercially means you can get high-quality turbines, but would cost a lot to buy and install. Using home-made turbines, on the other hand, would require a bit of work by hand but are cheaper. Materials for home-made turbines can cost you only by the hundreds, while commercially made windmills may cost you thousands to acquire.
Power Lines
If you plan to invest on a wind power business, you would need to be like the big-time power distributors and install power lines from your windmills or power source to your clients. Fortunately, power distributors nowadays also buy power from independent power distributors whether they are using natural power sources or fuel fossils. As a windmill power generator, you are in line to become one of the power distributors feeding power to the local power company.

Your Questions About Wind Generators For Boats
James asks…
What kind of boat do I need to go from Auckland to Fiordland?
Here is a link that shows the locations. What kind of boat do I need for this journey? I will be hiring a boat for the trip.
P.S. how much fuel does a boat usually consume? Please provide the type of engine and amount of fuel it takes for every 100km(or any other variable)
admin answers:
Sailboat won’t take any fuel at all, except for what might be required for a generator or if there’s no wind. Most sailboats will average around 8-10 knots so the trip would take a couple of days.
Betty asks…
How could I generate electricity in an underground bunker?
I know about solar panels and wind turbines but either will have to be above ground. Petrol or diesel generators are to loud and fuel isn’t cheap these days.
admin answers:
Hello
Rig up an auto alternator to an exercise bike running a belt off the bike wheel to the alternator, connect to a couple of good 12 volt batteries (deep cycle boat batteries would be best) wired in parallel from battery to an inverter of around 500 to 750 watts this will be enough for lighting, radio, and small toaster.
Now of course you will need to set up an exercise routine for running the alternator but you will keep very fit and if their is a few you can take turns and all keep very fit!
If you could get more batteries and larger inverter you would be able to run a small kettle as it’s only on for minutes so batteries would cope.

Your Questions About Wind Turbine Technician Salary
Richard asks…
do i have traits of a sociopath?
i can’t settle for average. i must move on to the next bigger and better opportunity.
career wise, in 2 years i’ve went from a fry cook->skilled laborer->field technician->wind turbine technician, i’m only 20.
my salary in the past 2 years has jumped in 5,000 increments with each job i moved up to.
i am very skilled in aceing interviews. i know what they are looking for. i know what questions to ask. i know when to laugh, i know when to make the manager laugh. i can make them bend over backwards to offer me the job, but i usually play fair and won’t take a higher salary offer.
i have strange hobbies. i enjoy reading electronics, programming, and mechanical books. when i go home, i study techniques and ways i can master my job. i want to be the best.
i love strategy games. it gives me a high trying to out smart the opponent.
i don’t desire socialization. but, at work, can be the “popular” one. when offered to party or go out for drinks, i politely decline.
i have 3 girlfriends. i tell myself – i will let them prove to me how much they deserve me, but, i kind of like the suspense.
i don’t really feel emotion. i can’t love. but i can sure show it, but, i will never feel it.
