So, based upon the link Bruce Brown posted, it looks like this is a new line of small capacity inverter generators. I'm guessing they didn't have the inverter technology in generators of this capacity before this, or maybe these are just newer inverter technology. I'm not really an expert on the Onan line.
But nothing in the Cummins release says this is their FIRST series of inverter generators, and the link posted by ScottG clearly states that the QD7500's use inverter technology, and I believe that line has been out for a long time for diesel rigs.
Mike, with all due respect, I believe you're misinterpreting the information published by Cummins.
