These divert loads can be used to heat shops or barns on cold/windy days.

You can also use a grid-tie as a dump load.  Best in parallel so, if the grid goes down, you will not boil your batteries and ruin them.

WIND GENERATION FOR THE BEGINNER

More basic info from Missouri Wind and Solar:

 
These guys make pretty good low-cogging wind generators in the 1500W to 3000W range.   They are industrial grade.

You NEVER want to discharge your batteries below 50%:

 
It is better to go towards 60-70% discharge.

HOOKING UP BATTERIES IN PARALLEL VERSUS SERIES

This is great when you are using 6V batts to make 12V system.  Rinse and repeat for 24V in series:
