To me, generators and alternators are like wolves and dogs. Related but different.

You are correct, sir - I misspoke. I've been shopping for inverters recently, so I guess I had "modified sine" on my mind. What I should have said was that the cost difference hinged on pure sine inverter-type generators v. traditional alternator-type generators. You are correct in stating that the traditional alternator-type generators produce a true sine wave, but the waveform is dependent upon the speed at which the alternator is run, and is susceptible to hiccups from misfires, etc. So, the inverter style DOES provide a cleaner waveform in comparison. BUT, my comment implying that "traditional" generators were not suitable for reactive loads was NOT correct. That applies to modified-sine inverters, not traditional generators. Thank you for pointing out my error! 73, Ravi Jonathan Guthrie via BVARC wrote: On 10/16/2014 2:46 PM, Ravi Ratnala via BVARC wrote: The cost of portable generators hinges almost entirely on two things: 1) Pure sine wave v. modified sine wave, and 2) attendant noise. Pure sine wave (typically, inverter-type generators) will cost more, as will the quieter ones, all else being equal. I'm curious how you get a non-sine wave out of a generator that generates AC directly. -- Jonathan Guthrie KA8KPN _____ _______________________________________________ BVARC mailing list [email protected] <mailto:[email protected]> http://mail.bvarc.org/mailman/listinfo/bvarc_bvarc.org
