These strange people are hooking a 24V battery up to some box full of electronic wizardry that will hopefully allow the 10' diameter 48V wind turbine to charge a 24 V battery more efficiently than it could ever do otherwise. Some might call this 'MPPT'. All I know is there must be a lot of highly pressurized magic smoke in that box and I hope it doesn't come out.
Due to lack of wind we put the 10' machine on top of the dump truck along with the 24V battery bank and the experimental controller. We drove it around a bit and the results seemed fairly impressive - about 730 Watts @17mph (measuring wind speed with an anemometer held as far away from the truck as possible). After that we took another run and the controller didn't kick in quite fast enough - the wind turbine voltage went too high and damaged the controller, so thats the only real testing we got done with that setup. Very interesting and great fun though.
Japp! Där åkte den magiska röken ut ur elektroniken!
We tried lowering the 12' machine with a truck at the end of the day on Saturday. I won't go into detail except to say that certain things needed to be done differently. The tower crashed - nobody got hurt (nobody was in the fall zone) but one blade got smashed and the tail broke. Another good lesson for everyone at the end of the workshop.
Vad är det som ger erfarenhet?? Misslyckanden!
