MPP PIP 7248-MAX: solar input (8000W) vs charger (4860W) question

Hi

Looking at the MPP PIP 7248-MAX specs, they both offer 8000W solar input and max bulk/float charge of 62V at max 80A = 4960W

I'm struggling here. Does it mean this inverter wouldn't be able to use the full potential solar gain (8000W) for charging the battery when no load is present ?

Background is; I'm planning my system and have 20x 335Wp 40.7Voc 10A Panels available. Battery is planned as LiFePo4 48V 280 or 560 Ah. First I was looking into 5048GK or MGX but those would only allow me to connect 10 panels as their PV input is only 1 MPPT with 450Voc max and 18A max. that's why I started looking at the MAX series and the numbers above don't make sense to me.

8000W max is 4000W * 2 - one 4000W array on each of the two 80A MPPT controllers.
