Perhaps this is something manufacturers are starting to do, so check your model before installing.

All A/C compressors have a start capacitor. Home or RV. A hard start cap is for an aging compressor or a low voltage condition. You don't add a hard start. You change out the original cap and install the hard start. it's just a start cap with a bigger kick. No such thing as a soft start capacitor. That is another Made up phrase in the RV world started by newbies. Soft Start is a trade mark unit made to help with low voltage conditions and/or borderline amperage availability.
It has lots of electronic parts inside. No need to add one just for a properly designed RV generator system.
