Any one have any experience with vibration issues with a Whisper 200 on a 80' LMWS 4" tilt tower? Vibration can happen with all 4 levels of guy wires but...
A permanent magnet turbine is normally used for battery charging. Th generator has built-in magnets that the turbine spins, to generate electricity. Permanent...
Hi all, I am looking for a grid connected inverter for wind terbine/PV which can be controlled through the interface controlled port (RS232, RS485, ...

Daniel, No, direct drive turbines are not the same as permanent-magnet generators. Direct drive turbines can use either permanent or electro-magnets. Vensys...
I'm considering putting up a tower for a home-brew 10KW wind turbine. I would like to use a 90ft monopole tower for the turbine, and need some ideas on what...
If the blades are properly balanced, the pitch identical on all blades and you have no magnet problems, there shouldn't be that kind of very noticeable...
... I've never used a LMWS 80 footer, I tend to use the SWWP 80 footers; the pipe is, I would suspect, alot cheaper in the latter. What exactly are you using...
Robert - The first question is; are all the machines acting the same way? Tower height should not have anything to do with it. If anything, vibrations should...

Hello FRom tyler tex Our State has reciently become unregulated with power companys. Our electricity has gone up 100% on our bills. My Electic bill which use...
Hi Farhana, Not sure exactly what type of 'control' you're looking for; I'm using Power-One/Magnetek Aurora inverters with the Eoltec Scirocco 6kW turbine that...
Hi Robert, You could try balancing the blades. Imbalance is probably the root cause of the problem. Not sure how to do that with a Whisper because the...
Bennett, windterra? the rating looks reasonable 167 W/m2, 20% efficiency at rated. more reasonable than many small wind turbines. forget the rooftop mounting...
Hi Rob, I think it might also be good to mention that any inverter that is an adaptation from PV to wind is going to need extensive collaboration between the...
A little, but if their website main page has anything at all to do with what they actually propose as a workable system, LOOK OUT! A machine as illustrated...
Other sources of vibration not mention yet, are: Rotor misalignment with the wind direction Gyroscopic vibration during reorientation Gusty wind Flow...

Jack, You are correct that building permits are issued only to property owners, not renters, unless you are acting as an authorized representative of the...
Wow only $6000 for a 1 kW turbine, not including tower? Where is the payback point? After it has been blown off the roof? taking a chunck of the roof with...
Hmm. Permafrost means always frozen at some depth. Turning the anchors down further into the ground might help. And/or moving one of the guy wire sets up or...
