another squall came through resulting in an output of 1854w , 1034w for the dual stator 45-90 and 820w for the 40-540v inverter, good stuff

Another big blow and 45-90 inverter put out 1039w ac and the 40-540 put out 930w ac, so thats about 1kw dc from 1 stator, over 2 kw dc from both, and it was not furling. so more to come.

Congratulations Fred, you have set a new personal record for your home made wind turbine built in a farm shed with only an arc welder & an angle grinder.

Just goes to show what can be done with lots of hard work and listening to some good advice along the way.

In fact the most impressive part is getting 1 kW on DC side from a single stator!! Go grid tie inverters with a wide input voltage range. Does it feel like braking a form "barrier" so to speak?

Thing is there is still more fuel in the tank as you have yet to receive the new improved 'Power Factor Correction Capacitor" that is making it's way to you.

Look forward to hearing more updates.

David

yep thanks for the help with the electronics Dave.
Turbine put out about 2.8 kwh today , I have to wire in a watt meter for the high voltage inverter as its meter zeros out everytime the inverter stops working from no wind.

The turbine starts turning at about 2.6ms wind.

One of the older 45-90 inverters started doing some strange things, dumpload started operating for no reason, had a looksee inside and found 2 small spiderwebs on the circut boards, and it appears some fet switches have blown.

I have got access to the online data from an anemometer above an orchard about 100m away from my turbine, Not 100% accurate because its not right next to my turbine,
but still good enough for a approx wind speed reading in relation to output,
so tonight I used it for first reading of 35kmh= approx 1500watts output,
will be able to do daily average etc.
I will eventualy buy a good pole mounted anemometer,one day lol
only have a handheld one at the moment, which is only accurate up to about 30kmh.

neighbours anemometer/weatherstation




anemometer with winturbine in the background,
The turbine will be getting a good workout for the next few days with some rough weather passing through here.

5kwh output for the last 24hrs from average windspeed max of 20kmh, with gusts up to 43 kmh

Hi Fred

Awesome that you have now got a 5 kW/h output over a 24 hour period. There are more kW/hrs of production to be made and not just from higher winds over same period, as some further tweaks will increase it's efficiency.

All that hard work has really payed off and also happy that I was able to assist along the way with some of the F&P stator and electrical setup.

Just thought I'd post a photo of my crude but very effective F&P stator test rig.



That 5 kW/h performance that you've got, has been partly proven on this very same test rig. Most of parts acquired for free (multimeters already had) and the largest expense was for the $99 Ozito 1200 W drill.

Just goes to show what can be achieved with the most basic of test setups and hundreds of hours spent proving it will work correctly. This was to try out various configurations to chooser which would work in the real world on a wind turbine.

Have learnt so much in the last 2 years and it's great that I've been able to help out on your wind turbine, as I still haven't got one of my own.

Thanks again Fred for allowing me to be involved, as started off with very little knowledge as of only 2 years ago.

David

Good stuff flc1, Dave, and what a great find at the neighbors. Is there any chance that you can get recorded data from the site? It may serve your needs quite well, and save you some money as well. ~ks

Thanks KS.
its data is recorded on the website ,so yep can get access to it at any time,and like you say no need to buy a anemometer at this stage.

I think it is updated every 30 mins.
