Re: Will this work, Electric ?
Its not that it is not possible, just not practical. At the minimum, you will need a high output 24 volt alternator/inverter.
3k watts @ 27 volts = about 111 amps. That's before all the power loss from inverting and delivering the current. 100 amps or so is easily delivered at higher rpm, but may be more difficult for long periods of time at idle.
Trying to run an ac from 12 volts would require twice as many amps which is generally not practical.
Rather than adding a second alternator, buying a 24 volt inverter , and a bank of batteries, it would be cheaper and less problematic to just buy a cheap generator, especially if you buy one from craigslist.
