Hello, I am a new member.
I have a project that I am working on, not to make money , but just because I like work around projects. I could just go buy something but what is the fun in that.
I have a 60v motor that I drive a 26' sailboat with. 5 12v batteries in series. I have 5 solar panels each with a controller each connected to a battery. So I have charge to the batteries to keep them full. But on a day when I use the motor more than I should I need a way to put a bulk charge into them. So I found a truck alternator with an external regulator, well it actually has a box that you just put 12v to and go full field. I have had it up to 90v. Now comes the problem, I was going to just run it to 72 volts with the rpm's and regulate it like that. Then I thought maybe I could find a regulator. I found a regulator that would work, then they said the alternator may not work, so I called around and found I need a much more expensive 60v alternator. I am using a 10 hp diesel engine. I could go to a 15 hp. I would like to get 50 amps at 60/72 volts. Can I just rewind my alternator with smaller wire? Can I just use it the way it is? I planned on using an external rectifier with 10 amp 200 PIV diodes. Where am I going wrong??
Thanks for any help, Dan
