I am glad I found somebody to communicate with. I am building an alternator from Hugh Piggots book. Mine has 9 coils and 12 magnets on each rotor. It is for a small hydroelectric turbine, so it will always turn at about the same RPM.
I want to put the electric output from the Alternator into the grid (grid-tie system) without using any batteries.I am wired into the rectifier now. that's is far as I have gotten now. I need a micro inverter with an input range of 10 to 30 volts. I need someone to show me how to wire this directly into my house electric  I need a diagram  and explanation and also where I can buy the micro inverter.  I could pay you a small fee for the information.

Jeff,
This is NOT A TRIVIAL Task!
If the phase and voltage level are not matched EXACTLY within less than 1 degree of the 60 cycles the "grid" has enough energy to rip your alternator physically off its concrete mounting blocks!  I have seen videos of 50 KW Generators weighing TONS haveing this done to them when not matched to the grid.
There is also a power factor to match as well. to get the energy "to the grid".
You are MUCH BETTER getting a transfer switch inbetween the grid and your breaker box ,
cut off the grid and use your alternator on less circuits as the "least expensive option" .

Look at grid tie inverters for wind power - good grid tie ones are ~= \$5000.00 for a 4 -7KW one.
DOn

The micro inverter he's talking about takes care of the phase and
voltage issues. The only concern I have is not having the battery
"buffer". If the grid is down, you are out of juice.

•                        Hi Jeff and All,                                           Or better Jeff
Message 9 of 14 , Feb 15 1:40 PM

Hi Jeff and All,

Or better Jeff is make the voltage/cycle/phase match and drive the  grid directly. Far less costly, more reliable, etc.  A soft start is easy to do, just use resistors starting then when sync'ed, short out the restistors amoong other methods.
If 3ph grid you just need to match the coils turn numbers to get the voltage.  If 1 phase then you'd need to wind a single phase set up.
The big advantage of hydro is direct alt to grid without batts or inverters.

The hugh piggott style alternator is not designed for direct grid
attachment. There is no way to synchronize the rpm. It's wild three
phase and requires rectification to dc, preferably for battery
storage, and use a grid tie inverter if you must connect to the grid.

Hi Steve and All,

While that is true with variable speed units but he was talking fixed rpm hydro which is completely different.   You'd need a 3ph grid to connect the standard 12 magnet/9 coil or change to even number of coils. mags and make a single phase stator. RPM depends of course on poles.  No different than other single/3ph alts on the grid.
How do you think other 1-3ph syncronous motors, alts run on the grid? There are many ways to match them up like I said, just google electric motor starting circuits. Most don't require anything except switching on like you do many times/day.   If you are playing with 50kw then there could be problems but 1-2kw just isn't a big deal.

Subject: Re: [axialflux] direct grid tie, Alternator micro controller

The hugh piggott style alternator is not designed for direct grid
attachment. There is no way to synchronize the rpm. It's wild three
phase and requires rectification to dc, preferably for battery
storage, and use a grid tie inverter if you must connect to the grid.

The ultracapacitors, if you caculate their life cycles, only last a couple years.
http://www.cde.com/catalog/inverter/

If you over spec the voltage, (use a 200V cap on a 100V peak ssytem) you may improve the lifetime.

You also may need to "fuse" the cap bank, and the additional impedence of the fuse, may decouple the bank.
