I have a new champion generator, 120volt at 20 to 30amp. The previous home owner had the same unit but 240 volt. The home has a professionally installed system for power backup but has a 4 pin 240 volt outlet as per photo.
My question is, can I adapt my unit to the 240 volt system which I think is split phase because it also runs a 1.5HP well pump motor?

Nope, no chance.
You can't get there from here.
The only way to do it involves some wild back-flips with a 5 KVA 120/240V transformer, but those are $400+. (you can occasionally get a find on Craigslist, but even then, the price will be greater than the price diff between this one and the generator you need.)
So back it goes.... if the well is a priority.
If it's not a priority, then maybe we can hook this up, but we'll need to see a much more detailed look at your generator interlock or transfer switch equipment, and how the panel is wired.
