You picture did not load.

Star delta start up is not a problem if the system is sized correctly.

Delta loads are not a problem.

Apologies, the picture says the following " Motor starts running for 25 seconds, with start and switches to delta after 10 seconds"

"Wye-Start" & "Delta-Run" is very common in 3 Phase.
A similar effect to a soft-starter.
Compressors are always an "issue", for any inverter.
The WYE connected inverters must be rated to handle the starting amps, for a short period.
