| Thats a good question. I don't think that it will. Well shit...I am out of | ideas now. I have built 4 or 5 ac to dc inverter for mobile CB's and HAMs. | Is it out of the question to just build an inverter that will convert the | 12Vdc to the 240Vac? That way I can build the inverter to handle the higher | wattage? Thanks so far
Build an inverter as big as you want.
Now how big is your alternator? How many amps can you get out of it? If you want 5000 watts, you're going to have to pull 416 amps at 12 volts, plus more for the inverter losses. If you can get an alternator to go directly to 240 volts, and a stable enough engine to keep the frequency close, you might be better off by eliminating the inverter. But if you do want a DC system, for example so that you can run batteries, too, then a higher voltage DC might be in order. Double conversion UPS systems in the 5 kW range typically use 48 to 72 volts in the DC section. If you can get an alternator to do that, it might help.
