FWIW, the US does not allow cord and plug connected grid interactive inverters, period, regardless of their power output. They must be hard wired.
The one exception which is sometimes pointed out is one brand which uses a non-standard (cannot inadvertently plug other things into it) cord and plug combination unique to their GTI AND the receptacle has to be hard wired in by an electrician.
That has no force outside the US, but there are legitimate safety reasons behind it.
Standalone/off grid inverters are a different story, but if you do have grid power too be careful not to interconnect them in any way.
