Wiring solar panels and battery bank
Yes. You can connect the 4 batteries in series. Each pair connected to a 24 V charge controller. But just to make it sure, you also need to check if you have to connect two solar panels in series if you want to use the charge controller in 24 V mode.
Word of caution: You need both the charge controllers connected to different panels. You CANNOT connect a single panel to two charge controllers and then connect the output of the charge controllers in series. It will create a short circuit and risk of fire. I hope you already know this, just writing for the worst case.
