eco switch and fuel consumption
Hi, We all know that inverter generators have an economy setting for low demand. Usually 1/4 of "full blast". As demand goes up to say 50% does the eco switch allow the engine to run at 1/2 spee...

My Honda 3000 with eco off runs at so-called full blast, but then when I turn on a good load like my PowerMax 100a charger, the Honda grunts and seems to get a bit louder. How can that be if it is already at full?
Once I get the 100a going I turn eco on and the noise drops some. After amps taper, the noise drops even more, till it is the same as with no load (not much noise)
In eco, if you add a load (and the gen does not conk out!) the noise rises up to whatever and drops off again when load is reduced.
If you do want to run a big load in eco then let the gen warm up first or it will conk out. Easier to just start with eco off and then turn eco on afterwards.
The reason it gets louder is because when not in Eco and at high speed with no load, it takes less throttle to keep the rpms.
When your AC kicks on and makes a load, the gen has to work harder and the throttle opens more, more power, louder.
Like driving 55 with your truck, no trailer, vs with trailer at same speed. The truck will need more throttle and will be louder with the load.
