Is it possible to use the feed from another inverter using 24V batteries as input to the Aux on Sunsynk

It should be possible as you will not be sending 24v directly to the aux but the second inverter that's connected to the aux will invert the 24v DC to 220v AC and this will then go to the sunsynk via the Aux.

Correct, before I acquired the sunsynk 48v I installed an axpert 24 volt at the moment I am splitting the loads between the two

It would make more sense to use the axpert as aux and  manage all the loads via the sunsynk

It may not be so straightforward. Remember the axpert is an off grid inverter.  To use the sunsynk aux as an input, it requires a grid tie inverter. With a grid tie the frequency / phase is matched to the host. The axpert may not be able to match its frequency to the sunsynk which may create issues. 
 

I still don’t understand why you want to use both inverters or if your loads are on the axpert, why do you want to use the aux an input 

As I now have investment in two setups, Axpert and 6 panels with a 24 v lithium battery and of late a sunsynk with a 48v lithium battery, I want to use both at the best efficiency possible. One way is to see the axpert as a turbine serving the sunsynk.

Does this make any sense  🤔
