Grid-Tie nightmares - why using inexpensive inverters is actually safer
"...I didn't believe that the system the WindGenZen folks suggested
for about 1/4th the price would compete with what I already had.
I bought the best for my family and it worked pretty well. I have a hybrid Solar PV and Wind System with
all the controllers and bells and Whistles.
After installing it I found the generators to be extremely tough
and the airfoil was outperforming my expensive rig on a 12 to 1 cost per amp savings,
which completely blew my mind. My wife is a Physicist and Teacher, and our son is pretty keen about making the smaller props.
Now when I have wind I always run the WindGenZen system and only run my other rig
when winds are light and I am trying to get some additional power."

I received the following email asking for A 10 Step Plan to becoming
energy self-sufficient. And I thought that perhaps this will encourage others
to take it one step at a time and make the move gradually. Unless you
have a large bankroll to be spent, that is the best way. You get to
learn before spending an arm and a leg and while learning, your
plans and budget may change so that the final system you end up with
is more refined and cost-effective than if you had just spent $50,000.00
before knowing what you were doing.
After the letter, I'll go into the steps:
In your opinion - what should be the first step for a 22 acre
hobby ranch to take? A wind gen with controller to run the
electric meter backwards?
Then what about adding a battery bank and inverter capable of
furnishing power to the house where you just unplugged
everything but essentials and even then alternated between the
freezer and refrigerator to keep their temps proper without
opening doors etc.
Maybe the battery bank might be used only when the grid goes
completely down by switching off the grid and having the windgen
feed the battery bank. As an intermediate step, a fossil fuel
generator could kick in until the battery bank filled up from
the gen- or the gen could charge some of the batteries while it
fed the refer and freezer etc and then get switched off
itself.
Couldn't a few of you come up with 'Ten Steps to self
efficiency' that gave the rest of us a starting point so we
could start going from A to B to C etc without trying to figure
out all the good info in all the bashing posts? There are a lot
of members just reading the b...h notes and saying 'WHAT????'
Not even the manufacturers like Mike and Andy do much to
encourage the interested member in getting started. Sure,most of
us way overuse electric power, but, we can learn to use one
outlet at a time when push comes to shove.
Personally I need to keep a refrigerator cold, a freezer frozen,
an oxygen concentrator running for my Mom & maybe a few lights.
I can get entertained with a transistor radio that will recharge
from a solar cell so I can be pretty economical when I need to
be.
The BIG question is where should most people start in the
learning process? My average wind speed is about 6 but many
days we have 13-20 steady speeds.
Now, let's review the letter and then the 10 steps:
First, the forum at
http://groups.yahoo.com/group/awea-wind-home are made up of wind generator
manufacturers, general contractors and alternative energy installers, end-users,
alternative energy and home power magazine editors and folks with a little machine shop
in their garage who love doing fancy things to motor/generators; it is a wide spectrum
of people who visit and often the home-builders get into some hot debates with the General Contractors
who want to do everything by the book (and charge appropriately).
As a result, there is a lot of finger wagging at the forum for do-it-yourselfers who
want to try new things that could, according to the contractors, burn the neighborhood to the ground.
The way to avoid that is to make sure your wiring is to code, your gen furls in storms and
your mast can take a hurricane or at least a good 100mph storm. Make sure your batteries
are in good shape and your grid-tie or inverter is sized correctly. In other words, you can
skimp on making blades out of wood and save a lot and skimp on items such as thick copper
cable/wire and have a disaster. We suggest as part of your education, you clearly
identify in your mind which components you can get surplus and which ones should be new.
That education is step one (below) and should be done before you spend a dime. And if you think that education starts with a magazine, be very careful!
There's an editor for a well known 'Alternative Energy' magazine,
The posters on the AWH site seems to be comprised of very
technical people who are probably competent in their fields but
they sure do NOTHING to encourage others to jump into the
alternative energy bandwagon. The most often heard cmment seems
to be YOU CANT DO...something or another.


who can be a nice guy, knows a lot about solar and wind power and even teaches classes with the otherpower folks... HomePower now offers a link to our free classes.
Great....and we'll go one better - subscribe to Home Power and we'll give them the blade carving class on CD to copy for subscribers and they can send it to you - FREE - a $29.95 value which pays for your subscription cost.
Eduhosting wants you to learn that you can unplug today
at a price you can afford - today.
You can learn this and spend 1/20th of the cost of solar PV, put up some wind power, save a bundle and then go buy solar panels with those savings without paying out of pocket.
Yes, you can unplug from the grid for about $1000.00 and a bit of elbow grease.
Next, the letter above suggests the first step having to do with a grid-tie and
running a meter backwards. Actually in my mind that is the last step, but for some
folks, just getting some revenue out of a small system is a primary goal. I don't think that
is an early game move.
To run a meter backwards would be to have a large system in place capable of
providing all of your electricity with power to spare to feed back into the grid.
Since our method suggests you go in stages and start small until you are educated
and very familiar with all aspects of your rig, I will put the grid-tie
issue towards the end of the steps below; after everything else is in place.
Next, the letter suggests an inverter that provides enough power for 'essentials'
and I think that hit the nail right on the head. If you have good wind, that would
be the first thing I would do - take the freezer and other constant draw
appliances off the grid and let them consume your wind power from your first rig.
You will need a battery charger that feeds your batteries when winds are light
so those appliances stay lit; you don't want your freezer to thaw with 500 lbs
of meat in it. And if your winds are good, that grid-tied battery charger won't
do very much work. There are even inexpensive ($50-$100) desulfators you can
get at places like Target now that charge batteries and can prolong their life.
Next the letter discusses a backup fossil fuel powered gen and if you are
planning on completely unplugging from the grid, that would be a wise thing
to get early in your game plan; when winds are light you either manually turn it
on or many of them will come on automatically if power fails. If you
are on inverters and batteries get weak and the inverter shuts down, your
gas gen could come on and charge up your system and shut down when
batteries were fully charged.
If you are planning on completely unplugging, that would be a piece of equipment
you'd want to get, but the cost, at $5000.00 - $15,000.00 for a good, professional
diesel gen would tend to push this down the list a bit; don't unplug until
you get everything else squared away and then, just before you do, get the
gas/diesel powered gen.
The letter discusses medical equipment, so that means not only is
a backup fossil fuel gen darn near required, but the size of
the battery storage system and number of wind gens needs to be
large enough to sustain power during windless days, even if the
fossil fuel gen doesn't want to start.
Finally, the letter suggests what I believe is true; most people,
if they could unplug from the grid, would make adjustments in
their life and conserve, whether it was a solar powered radio instead
of a 5000 watt entertainment center, or simply shutting off lights
when you leave a room or getting automatic dimmers for that sort of work.
The one thing the letter does not mention is the big roadblock to
becoming self-sufficient - government. Due to permit headaches and
installation regulations, home built systems are difficult to install
in many regions. I believe that will only change with public pressure.
And so, the first step is simple: make sure you are allowed to
use a home-made wind gen, battery bank, inverters and a subpanel dedicated
to your alternative energy system, that can feed an isolated circuit of
outlets and lights, freezers and water pumps in your home.
If you can't get that past city hall, then you are faced with
three choices:
And for those who want to apply elbow grease, save a bundle and get your plans and permits
to create and maintain your own system, read on. We suggest you do the research to
find out which method is best for you, your region and budget.
As a retired law clerk, I am always for public action, assembly,
cameras at Board meetings, public access TV to broadcast the decisions
politicians made and putting so much heat on political offices
their toilets boil - literally. Nothing is finer than to see a large group
of citizens educate a political body with facts and not some blind
dogma from some 'expert agency' and then one educated, to see the
politicians make sweeping changes that benefit the citizens they serve.
If you want a first step in almost any new venture that is
under the watchful eye of government, get organized; make flyers,
hold private meetings, develop a strategy and make sure everyone
goes to those meetings and is heard and bring a video camera and
make sure the tape makes it to public broadcast so everyone in
the region can see how the politicians voted. That to me, is the first step.
Organize your community.
Here are the 10 steps in order. That order may vary, depending on
your political climate and how many of the do-it-yourself tasks
you farm out to 'experts';
If your political climate is favorable and you can get permits for
home built wind power, then you are in luck; you can spend your money
on a 1000-2500 watt generator and a good 3000 watt inverter, 500-100 ah
of batteries and make your airfoils yourself. That saves you a ton of
money and even the rebates and reward programs of government don't
offer a cheaper way to start.
I suggest you start with a cheap 4 foot doug fir blade. It is easy to make
and will give you the skills to make larger airfoils out of better wood. Once
you can make a nice 4, a good 5 and a very nice 6, you can try your hand
at the 7s, 10s and 12 foot diameter airfoils and your blades will look good,
run right, be balanced and be quiet. If you jump right in with larger
blades, you are almost sure to mess one of those key aspects up and
that can be a disaster; large unbalanced blades can kill and at best,
will never make the power of a good airfoil you knew how to make.
You will have learned the basics without spending an arm and a leg for
the education.
You will have also learned how much power your region/site can actually make
with that gen, without spending $20,000.00 - $50,000.00 for a gen that sits
idle most of the time.
If you live in a place like Hawaii with great wind, you are darn near
done. Two large 10 foot generators and a steady supply of wind power
can easily take a family that conserves off the grid for most, if not
all of the year. Trade winds are a beautiful thing indeed.
Want to sell power? Fine...develop a circuit that does that job and
leaves your home pretty much out of that equation.
If your home goes a full year on your system and your utility expense
is a flat-zero, it's time to consider going offline permanently. This
means you should have that backup gas/diesel gen and if you have the money,
a few extra solar PV panels and batteries, a spare inverter, brushes for
the gen and parts for the towers and mounts; in short, you want to regroup
and get the maintenance issues of your system all squared away before
unplugging and finding out one gen was worn out and you didn't make it
a month before having to rely on your gas fired generator.
Make sure your system is absolutely bullet-proof, works 24/7/365 days
a year and you understand every component. If you built it yourself,
you will and that, in my mind, makes it 100% safer than anything else
you could possibly buy.
And with that knowledge, your payback period for each new gen/component is
only a year or two instead of 5-10 or 20 years as most systems require. That
means you learned to produce electricity for less cost than a multi-million
dollar mega-watt tower; you learned a lot. Hopefully your local politicians
learned something along the way too.
This means you have an opportunity to educate your neighbors and community
with your photos and stats and that is the last step...bring more people
into alternative energy, show them it is affordable and safe and practical,
that wind generators won't burn a place down or fall on a roof if set up
correctly and that anyone, even folks with tiny budgets, can do this
if they are simply willing to supply some elbow grease.
And for those of you who noticed there are 11 steps in this list,
need I remind you of the old saying '...the best laid plans of
mice and men...'
While this page concerns home-built systems, for folks with cash and
not much time to spend, here is the quickie, five step plan recommended
by a professional installer and even we have to admit, it is a lot
easier if you can afford it or it is required:

These are the 10 steps I would take, one at a time, to becoming energy self-sufficient.
Along the way you learned a lot about the gear without breaking the bank, you
learned to install safe wiring and circuits that didn't burn the house down and
they won't if you don't cheat and use the right guage wiring. And you learned
just how much power each generator can make all year long, and if you learned
to make airfoils, you learned how to do it cheaper than anyone.
Option 2 requires a substantial investment into a piece of gear that can and
does fry. I have seen many expensive grid-ties cook when there was a surge
in the system or some home owner was tinkering and arced a wire and took out
a $3000.00 piece of gear. Personally, if I had all the power I could use
and wanted to sell the excess, I would install a dedicated system for
that and never let it have anything to do with my home. When I needed
power I'd charge my batteries from the grid, from a fossil fuel gen or
from solar PV panels.
