To get the best performance from your fnp turbine you can find online at Alibaba.com a range of mppt gridtied inverters and mppt off grid inverters and chargers that are nz/au certified. With ac or dc input, with one of these inverters you could expect to get between about 1.3 to 2kw from a setup the same as mine.Setup details are here on page one of this thread.

photo showing one way dampner fitted along top of the tail ,to stop tail hitting back too hard on seat during storms, my first turbine did not have dampner and nearly snapped off top of pole during a storm.

Hey Fred

Just a thought, as to a simple modification to your wind turbine.

How about you try and add a "capacitor voltage multiplier" and place it in parallel with the main rectifiers?

I think it could give more power output over it's operating RPM range that I've seen you've plotted in that Graph.

Cheers

Gday Dave

Yep, good idea, Il have to get a larger inverter to match that modification though,

The one Im useing now is only just large enough for the current setup .

Hey Fred

Sounds like it could run on the dump load too much in high winds considering your current setup described in this same post. Waste of good energy...

Oh well another rebuild must be coming, so look forward to the increased power output results. Yours is turning out to be a very good Dual F&P, "all thanks" to those awesome Black rotor caps on 36 pole copper stators aye?

Cheers

when I pull it down in a few months time to grease bearings etc Il put a multiplier in n make another change aswell.Then we should have some warm cables.

Hey Fred

That looks like an "Ultimate F&P Dual" Wind Turbine to me, considering it's only using 2.4 m set of blades and gearing.

Imagine what would be possible using 3 m blade diameter with more stators direct drive?

My guess is you could get close to 3 kW peak output power if setup correctly in wind like that...

Cheers

Cyclone debbie has been with us for the last 2 days,untill this morning.
So the windturbine has been pretty busy for that time.
Last night we heard the turbine start to make a squeaking sound, the key had broken on the blade hub ,so the hub was starting to spin on the shaft,
turned the inverter off so the dumpload would kick in in the hope of stopping turbine, but it made no diffrence,the wind was just too strong, so we just went to bed, ha!
Got up this morning to check the damage, and the hub had worn about 10mm off the shaft , hub n blades were just flopping around on shaft ,hitting turbine housing.
Good thing we have started a new build already.We got 4 years use from it before this
so cant complain too much ,



there was a spline on that shaft.

Hey Fred

That's a bummer, so new build will be happening sooner. Will need to get the capacitor doubler built up for you and in the post...

Hey Fred

Any update on the new wind turbine build?

Cheers
