It sounds like your inverter is at fault. You will need an inverter tester ( most good service techs will have one ) to prove that the output to the compressor is correct. If the inverter is okay then it will be the compressor at fault with a location error or it is simply seized. A common fault that caused this was the eev remained closed (coil failure ) and caused the compressor to over heat.

Your split system is an inverter model. In it the compressor is powered not simply from the mains thru a relay but from a special and very complex set of converters: a rectifier to convert the incoming AC current to DC and then uses pulse-width modulation of the DC current within an inverter to produce AC current of a desired frequency to power the compressor.
In your case the unit that provided the final AC current to the compressor has failed. The fact this happened a few days after you have started using it is a clear indication of manufacturing defect - some of the electronic components used in that inverter were of a low quality and they haven't been able to cope with the stresses so they failed.
This is something that only the dealer (and its repair crew) can solve and it's covered by the warranty - time to call them. And in the mean time disconnect the unit from the mains.

Your AC unit should be still covered by warranty, get the installer to check you AC unit.
