What are you going to do with the ganache after it's made? How often do you need to make this batch size?
We routinely make what I'd call a big batch - albeit smaller than what you're asking about! - 6# bittersweet choc callets, 24 oz butter (in chunks) and then 6# of cream. I boil the cream til it's climbing the pot and just when you think it's going to boil over, I pour it over the chocolate callets, rock the bowl a little (it helps to have the butter in the bottom of the bowl; I like the extra body it gives to the ganache). and let it sit for a few minutes before I whisk. I just have the choc/butter in an extremely large mixing bowl; we use it for glazing cakes, filling tart shells and let the leftover firm up for filling/coating cakes. The mixing bowl is about the size we can manage easily; I don't think I could handle something bigger/heavier trying to pour/ladle out a fluid ganache.
I myself have never used a steam kettle, but if you're heating the cream then turn it off and add the chocolate (slow and steady) you could whisk til it's melted and emulsified. Curious to see what others suggest!
