Those panels would work pretty well on your system assuming it is a 12V battery system?
If it is 12V, then that controller can charge with about 280W maximum and you have 345W of PV maximum which is a good amount of PV for that system.
Your PV short circuit current is just below the MPPT maximum, so I can't see anything wrong with your setup from what I can tell.
