RS450/200 MPPT Tracker current limit of 16A or 30A? Manual states operational input of 16A and an absolute maximum of 30A, which do I work to?

Question

Trying to configure my series strings for worst case scenarios on my ground mount using Sharp NBJD-585W Bifacial panels. I have calculated separately for above grass, white gravel and snow (Although very rare in the UK, it happens). I have added a 10% variance tolerance as stated in the panel manufacturers datasheet, +6% for grass, +20% for white gravel & +40% for snow for potential bifacial gain.

My panel values according to the datasheet:

14.09A ISC @ STC - Grass =16.5A - Gravel = 18.7A - Snow = 21.8A

15.59A ISC @ BNPI - Grass = 18.2A - Gravel = 20.6A - Snow = 24A

17.47A ISC @ BSI - Grass = 20.4A - Gravel = 23.1A - Snow = 26.9A

Obviously the worst case scenario doesn't come close to the 30A absolute maximum, but does exceed the 16A maximum operational input current. Any advice here? Is this tracker suitable for these panels?
