For your soft start, are you looking at zero-crossing switching? Over what time period do you plan to accomplish this soft start--how many steps? Are you able to diagram what it would look like? I'm looking at the possibility of a soft start of a water pump from 120V AC from an inverter and 12V battery. (Not quite the scale of what you are doing.)
