Not a problem. This type of controller is current limiting; it will only pass 60 Amps maximum no matter the amount of panel on the input or the load on the output (save a dead short).
Even Morningstar's little 15 Amp MPPT controller can be "over-paneled".
You may have noticed panels don't come in precise Wattages of infinite variety; you always have some leeway to work with.
The old Outback MX60 is a 60 Amp controller but can actually be cranked up to 70 Amps, for example.

So bottom line: no fire hazard running 840w through a 800w max controller...
I kept thinking the extra watts would overheat something..
So it just "rejects it" instead?
Is that correct??
