Your first mistake. :W

I understand that what works for 1 person might not work for another.

Apparently not, as wishful thinking overcame your "understanding" ... what made you think you'd be the exception? :R

It worked perfectly for almost 2 hours then went into overload.

Of course it did but that doesn't mean the genset still wasn't running right at the edge of it's capability. What Mr Wizard refers to as "heat creep" is an increase in compressor head pressure - the longer it runs, the greater the heat load it has to deal with, so the more head pressure will increase. The compressor increasingly wants to draw even more power from a generator that can't supply it so what happens? - the only thing it can, it goes into overload and if properly designed shuts off power to it's output receptacles, thereby protecting the genset's inverter. You should be happy this happened, not discouraged. :R

Bottom line - while your genset may initially successfully start and run your A/C under some conditions there's no guarantee it will continue to successfully cycle the compressor as temperatures rise or as operating elevation increases. If that's your expectation then you need a genset with greater capacity.

And yes, I've been there with two different Honda EU2000i gensets, three different A/C units all equipped with a SUPCO SPP6 hard start cap. ;)
