battery back up
Ian asked:


I also have a wind turbine or windmill that has about 20 somthing volts or lower (not more than 23. and lower) the watch battery is 3 volts. If i give it one good turn while the wind turbine is connected to it will it charge back up or more than one turn or will it just destroy it.

battery backup
thinktankthing asked:


…have to produce in order to be linked to the main grid? I’m not really interested in the battery backup system but feel free to include that info as well.

Could you explain these NUMBERS to me like I were a vegetable please?

-generator rpm
-kW
-voltage

Please tell me how they are related and whatever else there is to it. Thanks
