No, not a 3-ph panel.
It might help to visualize that each phase of the 3 phases as a single, independent leg capable of powering XX amps (to the neutral leg)
Each leg of the three is capable of running single ph loads.
Thus, if you can find a way to split your ac breaker panel then you could use two of the three phases in that manner.
However, (there's always a "but", right?)...
This is a three phase set and is meant to power loads between phases.
This means that the neutral wire is not meant to handle all the power that the alternator can produce, and, in fact, is not sized from the factory to do so.
At some point you risk overloading that single neutral conductor.
Also, by using the generator in such a manner -were you to heavily load two of the three legs (to the neutral wire)- then you are unbalancing the alternator.
That is a somewhat lesser, secondary issue. One you can get away with as long as you understand it and the combined loads don't overload that neutral wire's ampacity.
For example, a severely unbalanced generator can exhibit heating of the alternator and 'chugging' or oscillation of the prime mover. That would be a worse case scenario.
In your case it doesn't sound like this would be an issue, but you need to understand it.
And, so, given all of the above, this is where the "but" comes into play. Because, as you see this isn't a normal operating scenario and, although it's definitely doable, there are some considerations that make doing so a bit more complicated.
Because of the above I very *highly*recommend that you find the resources to hire a qualified expert, either a local electrician who knows generators, or, you could call Kohler, who would find a local certified contractor for you to hire.
Another contractor you could contact is Alturdyne in California. They employ qualified generator techs around the country and would be glad to send one to your location.
None of that is cheap, but you be a wise man to do this. It would also get you going quickest and, most importantly, safely.
It's up to you how you proceed from here. Just realize that in the real world of life, the world we all live in, you pretty much get what you pay for - and... what you don't pay for.
In the long-term scheme it's well worth considering getting some outside, hands-on, help. IMHO.
