Powering trailer with an alternator
This is something that's been kicking around in my head. I've been researching alternators and i've seen 2 that have an output of 370 amps at 1200 rpm. If my math is correct then that is 4440 watts @ ...

As a designer and owner of such a critter (385 amperes at 28 volts) the idea is valid. At the expense of weight a suitable engine can operate at say 1,600 RPM under FULL LOAD 24/7 364 (one day in hours for maintenance). Try operating a Honda for a solid year and then shut it off and yank the cord. The engine will spin for a half minute cause it ain't got no compression (worn out).There have been reports here of Hondas going over 15000 hours.
I haven't kept track of mine, but they get a LOT of use. Don't know just how many thousands I have on them, but it for sure is multiple.
Rule of life.....nothing's perfect. Almost everything has strong and weak points.
It is VITAL to control alternator voltage PRECISELY with a system like this. Within a few hundredths of a volt. Adjustable voltage to allow the inverter to see an exact predetermined voltage to achieve output voltage. Frequency will be correct but I highly suspect the internals of a MAGNUM inverter to be of slightly higher quality than the inverter of Honda generator. I use a diesel prime mover and it operates at 1,300 RPM.
