Hi guys
You may have seen some of my earlier questions and I appreciate your help before. I would like your opinions once again. I am building a 10 foot turbine like the older ones on the Otherpower web site using twelve 2" x 1/2" round magnets on each rotor and 9 coils in the stator. I have the genny mostly built but am now about to make the stator.
I have an APC 48V 3000W UPS but as it draws around 80W no load from the batteries I will be buying an inverter. I can build the stator for 12V or 24V easily (not sure about 48V).
- Which voltage would you suggest I build it for?
- How big should my battery bank be to match this wind turbine?
- If you think 48V any idea how many turns required (given that 60 to 70 for 24V and 30-35 for 12V) is it just doubled that for 24V ie 120-140. In the Wind Farm turbines the stator is wired in Star instead of Delta as in the older design. http://www.otherpower.com/windfarm1.html
Would I be better to keep this configuration if going for 48V?
I like the Idea of using 48V as the losses in the cables are smaller and I can use my APC as a backup, however the inverters seem to be more expensive. I am on a tight budget and was hoping to get the inverter for under a couple of hundred UK pounds.
This system is mostly being built for fun but I intend to run some of the house off it (probably a few lights initially and add stuff if everything goes well) with a switch over to grid for periods of low wind. My cable run from base of turbine to shed is around 50 yards although if this too much I guess I could build a wee shed just for batteries and inverter and run 240V back to the house.
Thanks
