Can one parallel a 100/20 and a 75/15 if each has own PV panels but share 24V batteries?

I read an earlier post of someone here having three 75/15 MPPT chargers in parallel on the same battery bank, not synchronising well with charging duties. I have a compact 1200/24 Inverter with three 150W PV panels (450W) in series running through my existing 75/15 to a battery bank of 24V 200A and I wish to generate a bit more energy to utilize the 1200W inverter better. Thought of just adding another 75/15 or going a bit biggere with say 2 x 300W panels through a 100/20 - but have some concerns of compatibility? Any advice guys? thanks

It should work.

If there are issues, it's because of defective products, software bugs, wrong wiring, wrong settings.
