So we are off grid and have a 24v system and right now we're strictly solar. We're wanting to add a wind turbine so we have power on a cloudy day but I'm having trouble finding permanent magnet dc motors that have a high enough voltage to rpm ratio to give me 24v at a normal wind speed. Is there any way to get around this? I found this diy article (attached) but it doesn't explain enough for me to know exactly how to build it. If anyone has any ideas on what I could use to get 24v at around 400 rpm or could explain better how to do the steps in the article (for someone who only knows a little bit about electrical stuff) I would really appreciate it!
