Integrating a secondary inverter on a system

I’m running an easysolar 24/3000 with a smartshunt and a lynk power in fused bus bar.
I have the need to run a small inverter direct from the batteries and for now I have connected a cheap one ain between smart shunt and the fused breaker to the easysolar.
My soc is working but I don’t like that the multi has no idea the other inverte is there.
If I buy a 24V 800VA Phoenix Inverter to replace the cheapo I have, can I make it talk to the multi/shunt so it knows what’s going in and out there and integrates it in the GX info?
If so, is this done via the v.e. connection or via bluetooth?
If bluetooth is that integrated or I need an adapter of sorts?
Thank you
