Growatt compatibility with Victron MultiPlus inverter?

I'm new here and looking for some advice on a system upgrade. I've been running a Growatt SPF6000ES with two additional MPPT controllers and three solar strings, but I'm looking to increase my system's power capacity to handle a larger electric load. I'm considering upgrading to a Victron MultiPlus II 48/10000 inverter. My current setup uses a busbar, so my initial thought is to simply disconnect the AC output from the Growatt, install the Victron inverter, and connect it to the busbar.

My main question is can I keep the Growatt and just use it as an MPPT controller?? I'm hoping to avoid the cost of buying more controllers. Is there any issue with doing this, since the Victron will be handling the AC conversion? Any insights or potential problems with this plan would be greatly appreciated before I make the purchase. TIA!!
 
To prevent conflicts with the Victron, just cut off the Growatt's AC output. Either unplug it or flip the AC breaker to turn off its inverter.
