Some perhaps relevant info from Emerson/Copeland: Side note: on a 7 year old building they had a soft start on the 250 HP fire pump. The reason is that it offers you plenty of benefits like: No, a soft start air conditioner is not more effective than VFDs. It is the charging of that capacitor that you are seeing as that 10x spike in current and after that, the motor will pull approximately 6x current until it gets to around 80-90% speed. In case of under voltage the compressor is switched off. It helps you efficiently use the power and save money & thats why VFDs are considered more effective than soft starter devices. Also with a soft start it is reducing the voltage for a very short time so that the motor can build up to speed, and then a set of contacts close to bypass the voltage reduction part of the circuit. If your AC will start conventionally, it will be vulnerable to so many problems. Variable frequency drives (VFDs) are more energy-effective than soft starters. The hard start kit is designed to give the compressor added starting current, that could be the reason that your generator is feeling the inrush surge.
