Limit for direct rollovers into the Solo 401k

Is there a limit to how much I can rollover or how many rollovers I can do per year from other retirement accounts into the Solo 401k? If I want to rollover more funds later can I do that?

From the Solo 401k's side, there is no limit on the amount that can be rolled over nor how many direct rollovers can be done into the plan.

The retirement account you are rolling over from may have their own limitations, but the Solo 401k does not as the receiving end.
