Advice for a generator that would just run the pool panel pump?

After our recent loss of power, I'm thinking that it would make sense to keep a small generator around just to plug into the (disconnected) pool panel. It doesn't look like the Pentair variable speed pump and panel would really need that large of a generator, but I can't really seem to find a "smaller" generator that does 220v. So I would love some advice on what size generator I should look for, and if anyone has found one that size in 220v that serves/could serve this purpose. Thanks!
