I have heard that adding a soft start system can decrease current draw, but have not seen a cost saving to cost of soft start comparison.
Soft start systems have nothing to do with reducing the kwh consumed.
When you start an electric motor (like the compressor motor), it will draw 2-4 times the wattage but only for a second or so. Once it gets turning, the draw almost immediately tails off.
If you are using a small generator, it may not be able to meet that peak load before going into overload and cutting out. A soft start is intended to reduce that peak load, so a small generator can get the compressor started.
