I'd buy that second 8s BMS and make two 24v batteries.
Redundancy is nice. If one of the batteries in parallel goes down for some inexplicable reason you still have one to rely on.
Also any load would be shared by the 2 batteries. A single "parallel pair" battery using one BMS is limited in the amps it can deliver. If I remember right the BMS you bought is a 100a discharge. If you pull the inverter's max 2400w you would actually be drawing over 100a due to the inverter's efficiency. (2400w / .9 (90% efficiency) = 2667w / 24v = 111a
That's more than the rated discharge of the single BMS
with 2 batteries/ 2 BMS you would only be drawing 55a or so.
