should eco-throttle always be on? - Page 2

It is obvious to "Me" that Ted, has NEVER looked at the Published Spec

Either that, or you completely misunderstand what "eco-throttle" is
designed to do on a conventional generator.
"Eco-throttle" on a conventional generator is designed only to reduce
fuel consumption when there is *no* load on the generator as in a
construction site running saws and the like. This is different from how
"eco-throttle" works on an inverter generator.

On conventional generators "eco-throttle" is designed to bring the
engine back up to normal RPM as soon as a load is applied, and these
generators do not supply the normal voltage or frequency when in idle
mode. This is not a problem at all for the applications they are
designed for, a circular saw does not care at all if the voltage and
frequency are out of spec for a half second when they are first turned
on.

If you put one of these conventional generators in "eco-throttle" mode
and hooked up just a voltmeter (no load) you would no see the 120/240V
or 60Hz you expect and this is *normal*, not a fault in the generator.
There will be some minimum pickup current to trigger the normal idle, so
a very small load like a single light might not trip it. If you read the
instructions for one of these generators, they are pretty clear as to
what the "eco-throttle" mode is designed for.

 just general background but there was no heavy load when testing, only about
1kW of power was running/needed and the conventional gen was rated at 6600
watts runtime power

In my experience with these critters you rarely need to turn Eco Throttle
off, only when you have a load that is hard to start.  Of course, if it's
that hard to start then it will probably have trouble running it anyway.
With this design if the inverter is overloaded it will shut down and you
have to turn of the generator and restart it to reset it.  I agree with
Vaughn that in cases such as these you are probably better off with a
conventional generator.
