I didn't even know they released the eco kit that provides the throttle stepper motor that is informed by load--something every portable inverter generator has! I contacted them about this eco kit and within less than a day they called be to get payment and shipped the unit. Also, I asked about getting the sound box and the guy said it came with the eco kit?
Anyway, I'm looking forward to less wear and tear on the engine, less fuel consumption, and less noise when not fully loading the generator. I've always been running a portable overnight to save fuel and not be the "guy with the loud generator" keeping everyone awake at the track all night so it will be nice to have the option to keep the NPS running if I don't feel like getting the portable unit out.
