The switch to 24V will definitely help with reducing the number of charge controllers since you only need half the charging current (amperage) you would need for 12V.
If you are considering installing Victron Multiplus or Quattro inverter/chargers, depending on the model, each one has a charging capacity of between 50A-120A (models 2000VA-5000VA). Rather than let that charger go unused unless you're running the generator, you could AC-Couple the Multiplus/Quattro with a PV inverter.
Here is a quick diagram I modified from Victron to represent your 24V system. You'll several other things (possibly auto-transformer unless you use 2x inverters etc) but it will give you an idea.
That's just one configuration and again it's missing several things. Another would be to use the AC-Out 2 on the Multiplus/Quattro for the PV inverter and that's likely what I would recommend. I didn't get to review the entire thread to make a complete layout but there is a chance this will be cheaper for you than running several charge controllers. Many PV inverters have multiple MPPT trackers so you can vary your strings size or types of panels per string. If you're using SolarEdge with optimizers, that will help with varied light per panel and mixing panel types. Will be much less wiring to deal with as well, since your string voltage(s) can be just shy of 600V.
The wired AC sensor is to prevent power from pushing back to the generator but there are other ways to do that as well that might be easier to setup.
