I'm confused - high-wattage off-grid solar - charge controllers?

Bossrox:
Your ?: Is there an input panel wattage maximum? Or does the controller take what it gets and only uses what it can make use of if the input power is more than it can push out?

That depends on the chargers design. Some you'll fry if you exceed the recommended input value others like my growatts, even tho the manual gives a max input, I can take my full 31kw's of panels & dump it into their chargers & they don't even flinch. But you should have a charger for each set of arrays that match the chargers input & you can daisy chain multiple chargers but there may be a limit how many can be daisy chained with some brands & mixing different charger brands & even same brand with a different output rating is a no no in most cases.
