From some ‘dogged experience’ ($$), I can now surmise little practical justification in attempting to run an air conditioner-generator combination through a fussy ‘pass-thru’ type inverter - Though I can well appreciate the Holy Grail of load sharing (e.g. more fuel efficient generator), this supposed benefit can become somewhat theoretical when it comes to managing (or transitioning to and from) a highly inductive-reactive compressor type load (a virtual ‘push-back’ on the power source), most likely an iffy ‘not one size fits all’ software situational issue that might vary per scenario (considering a variety of variables) ….Short of some on-site, dicey over-writing of the inverter’s fussy programming sensitivities, adding a stand alone ATS Switch (a bypass affair) begins to make sense, and can readily overcome this malady while providing some additional benefits (aforementioned) as well…JMHO,
