I probably should have stated at the beginning that this was for a solar setup with a charge controller.. So it is really not like a regular dc battery charger like a marine setu would have a need for.  Dont need a voltage regulator or engine speed controller when I am going to use a solar charge controller to do all that stuff.. Maybe down the road I can get a nice aio inverter charger. Those will start and stop the generator when the battery voltage gets to low..

Also this is probably not the same company they were talking about back in 2010.. That was missourri wind and solar and they had a bad reputation and were kinda liars.. This company is wind turbine generator. They make pma for engines hydro and wind. They have been around since the late 90's I believe. The rotors are all machined from new not GM rotors.. The stators are almost 3 times wider than what is in like a leece 110-555.. They are not GM stators.. 1000's sold since 2002 100% positive feedback.  I dont think a car or truck factory alternator is gonna be able to make 60 amps at 58-60 volts reliably for a long time without some major rework..

And these ma's make their power under 2500 rpm

Yes c.e. niehoff.. Yes i read about the specs on those they are pretty neat..up to 400 amps on some models. But I need 48 volts

The manufacturer is Niehoff.
Now I have to find which model.

It's something else.
I have to go back in my notes.

Iam half way done paying for a new victron multiplus 2. 5000 watt 48v. Have 4 12 volt lifepo4 batteries in a 48 volt setup. Only have a small array of solar panels.. So I am going to use a engine driven something to charge the bank most of the time for awhile.. Easiest thing to do is take my 2500 watt belt driven ac head and rectify it to 100-150 volts dc to run into the charge controllerr . And let that control everything.
I didnt like the way david poz built his 48 volt charger. And a good 48 volt alternator is $800-1000.

Most of that was just talk.. Based on no testing.. I read it.. Not arguing which is better..  If anyone gets a chance , look at the independent video of the 24 volt version pma. No smoke and mirrors that i can see. This isnt a gm alternator with magnets glued on a factory rotor.. We are a long way from 2010..  Thanks

hi henry the humvee alternators are leece neville dual voltage. 12 and 28

I think there was a discussion of a Military alternator is used on HUMVEE's. It's huge, heavy and I believe it's dual voltage. My understanding is they might be more efficient than most alternators. Unfortunately, I can't remember the name of them.
