Hi all, i have two projects for wind turbines for my allotment, one using a treadmill motor (4500rpm/12v/2hp) and recently i won an lg direct drive for a £1 (36p stator as above post). I was planning on using the first motor for a hawt and the second as a VAWT as i dont have anywhere i can put something up high. The land i intend to use is at the top of a valley - can get very windy, but i can only go about 10 - 15ft high. i bought a cheap controller (see pic) and have mmpt controllers for solar. Can i cheaply combine one of these setups to include 300w solar system which i already have AND also I need to add a dump load onto the 300w controller or can i add it to the whole solar/wind setup - if so how? Have 2 AGM 12v batteries and plan to run some lights, pump, fan = 200w max. But if this generates more, i may use it on my house. Out of curiosity how many watts are ppl getting from the F&P 36 pole?  |

Hi druist I've been able to get 1800 W at 650 RPM from a single 36 pole F&P stator. More power output is possible. This was using power factor correction capacitors whcih need to be set up correctly. Check out my other topic 1.5 kW @ 600 RPM with PF correction for more detailed information. Also have a look at flc1's f n p gridtie windturbine, triple stator as I know he has got 1 kW peak from a single stator on his new wind turbine build. David There are realities if you do not accept, will lead to frustration because you will be spending time on wrong assumptions and the results cannot follow! The Dunning Kruger Effect :) |
