DC bus configuration recommendations for running two inverters parallelly

Hello Experts,

Is it possible to run 2 inverters with a common DC bus parallelly?
I have made a rough block diagram of what I had in mind:1672378675225.png

With the above configuration the ripple generated from Inverter 1 would not effect Inverter 2 or vice versa?
Let me know your thoughts...

I am sure you can do that, though there might be some interaction if your DC supply sags, such as when one or both motors start up or stall.

Victron inverters can be run with as many as 6 in parallel.
How much power are you going to dissipate in the diode?

Hello, its not a dedicated diode, will use a switch for this. planning to use a inrush controller, something like the LTM9100 ,
Q2 in the below circuit
