Input vs Output question

Input vs Output question; I am connecting my Victron’s 100/50 MPPT onto 4x 200W 24V solar panels (panels are rated max 37.6V & 5.36A). Panels will be connected in parallel, therefore max MPPT input would be 21.4A under perfect conditions.

Q; I am worried the MPPT’s output current may be in excess of 50A. eg. if input current ever reaches 21A, at 37V, does it mean the output current at 12.5 volts would be 62A ? (WAV rule, watts=amps x volts)

The controller will limit the output to 50A.
At 14.8V battery Voltage then you will be harvesting 740W from your panels. Your system is quite well dimensioned.
