    Greetings,
    Looking at other threads regarding this topic, my question is, can I achieve 230 volts, 50 Hz line to neutral in this configuration when changing a 3 phase generator to single phase.

    Depends on what your original three phase configurations provided.

    If it originally had a 120/208 or 230/415 three phase output then yes.

    Yes it is a 415/230 three phase generator with a 32 amp 3 phase socket and a 16 amp single phase socket.
    This customer of ours wants it converted to single phase only. I have wired it to single phase parallel zig zag. I am getting 115 volts L-N and 230 volts L-L. The only supply we want is the 230 volts, 50 Hz.
    Looking at yours and other sites it seems this is only possible in 60 Hz. Can you please advise of changes needed to achieve this. Thanks.

    Since you are getting the required voltage just move your common to ground connection lead over from the center tap to one end.

    As far as the generator is concerned it more than likely does not care where the windings are actually connected to the common and earthing points.

    From that you will have your 230 VAC single phase output.
