16kw Generac Whole home generator

I am having solar installed at my home and while my electrician is here he’s going to help me run the CTs so I can monitor my 16kw whole home Generac generator. Which size CTs do I need to monitor? Will the 50a work or do I need to move up yo 100a?

You might be OK with 50A but to match the nameplate rating you should use 100A.

Thanks! Placing my order today.
