At that price of his unit I dought his unit has anything special in
voltage regulation that will do any better than keeping it at less
than 5-6v swing, my 7500 Generac with avr is that way. He still needs
to manualy make a set point based on load used. 3600 rpm is still
60hz, and varies with rpm. Im sure an adjustment to rpm is easy to
do.
