>You can connect any amount of any type of charge controllers to the same battery pack, provided they have the same voltage ratings and they all support the given battery chemistry. If you mix different brands, it can cause some mild inefficiency issues with different charge curves, but as long as it's the same brand, you can put 10 of them on the same battery for all they care. Of course this doesn't apply to the PV strings, each charge controller should have its own string. Ideally choose a type that has adjustable voltage thresholds for CC/CV/equalizing, the one I linked has that.
OK, this is very helpful. To summarize.
PV Array 1 to charge controller 1 and inverter to battery bank.
PV Array 2 to charge controller 2 to battery bank
Thank you.
