When I first built this alt a while back I tested it with my 49" blades. It did very well at 24 volts but stalled baddly at 12 volts.
Today I tryed it againg at 12 volts but with my blade extensions. This took the blade to 61".
At 49" and 24 volts I pushed the littel alt to 1296 watts and it stayed stone cold.
Today with the 12 volt battery load and with the 61" blades it got quite hot.
Here are the wind test #s.
10 mph 63.5 watts.
15 mph 130 watts.
20 mph 196.5 watts.
25 mph 331.25 watts.
30 mph 432 watts.
35 mph 630 watts.
It did more power at 24 volts with a smaller blade and no heat.
However I'm thinking of flying at 12 volts. The tower cables will be longer (more resistance) and I can shut it down in higher winds.
Heres a couple picture. I'm also trying out the nesel(sp). Seems to work well?
It has been sugjested my #s are most likely scewed by the wind excelerating over the cab of the truck? That may be? However these 2 tests were made the same way so at least the diferances are real.
Its all fun.
