To do what you want, you would have to go into the inner control of the A/C and intercept the feed to the compressor motor, and insert a soft start circuit at that point. Whilst I am sure it is not impossible, it would be very difficult.

The other method is to bleed off the high pressure side of the compressor back to the low pressure side so when the compressor started again it wasn't a virtually locked rotor start due to the pressure still on top of the piston. This bleed off solenoid could even remain open until the compressor reached full speed, this would reduce the high start current as well as quieten the restart because the compressor would be unloaded until it reached operating speed.

I would think that you would have to go to Dometic or other company and look at the specs for their soft start systems and see if it could be adapted to use with your Ibis.
This is a link to the Harrier Dometic soft start inverter system. What a conversion would cost would have to asked of an Aircon specialist if you could use the electronics for the Ibis.
Our three year old Ibis does not start up badly its preety smooth go figure? But theres been a lot of people complaining about it so thay definitely have a problem,cant figure out why ours is ok...

MMMMM what would happen when you suddenly drop the load on compressor running flat out?????

As in? It is an electric motor, the max speed is governed by the voltage and frequency, but why would you dump the load while the compressor was still being driven, simply open the bleed back valve the same time as the power is cut to the compressor. As long as there was a non return valve the other side of the bleed back valve the high pressure refrigerant would still be there knocking on the door of the TX valve if the system uses one.
I had often wondered about the value of an accumulator like those used in hydraulics and water systems to store high pressure so the pump off time was extended and a softer start up period when the pump restarted while the pressure built up again. Inverter technology made such a system redundant so I never bothered to follow it up.

The newer Ibis 3 spin up the motor first for a few seconds before engaging the compressor clutch.
This is designed to reduce the start-up power load on generators, but makes the clutch clunk louder that the older design.
