BTW your generator was"Hunting"
Up and down speed oscillation is called hunting
But I Can Not understand it for you !

Thankyou all. WA8 makes a good point as mine is the 80amp model BUT by 'surge', I mean the generator doesn't only rev up; it oscillates up and down in revs after an brief, initial high rev. It is becoming clear that the batteries are getting long in the tooth and when low in charge, the smart wizard on the converter is sending high and medium charges to the batteries which in turn causes the econo throttle to attempt to accommodate. I will install a couple of new batteries and after initial charge up, drain them half way down and test my theory. Will let you know findings.
So prove it with the microwave or 1300-1500 watt electric heater.
Batteries that are going bad, sulfating ,act like charged batteries, thus reduced load.

A 9280, in theory, can suck around 1100 watts.. if the batteries are low and it is first engaged.. And yes, this will make a Honda EU-2000i, kick into HIGH gear (Surge) as well it should. I mean its over half the rating of the generator.

If the gen is slowing due to the carb and it is under enough load it will not be able to handle the load and will trip out.
Simple as that.
(trip out? The overload light will turn on and the gen will return to idle if eco mode is on and remain wide open, and the only way to get it out of trip mode is to shut it off and restart)
If the gen is slowing because of load change it will slow normally and rev up as the load increases... Simple as that.

Thanks for the reply MM49. Why would this occur now (after 4 years)with the old generator and setup. I would be quick to agree if it was only happening with the new generator but both generators are reacting identically when I throw the switch and connect the batteries..... BUT, the problem seems to be overcome if the generator is allowed to run for about 15 or 20 minutes and then connected to the batteries.... so you may have something. It's just that they run so well otherwise, even under very heavy loads.

Try a higher octane fuel, or add some Nitromethane RC fuel from the hobby store
To the gas
But I Can Not understand it for you !

How old is the conveter?
What is the voltage at the converter AC input / DC output?
Do either vary during the RPM change of the generator, how much?
Have you got a AC clamp on amp meter?
How much current is the Converter taking?
How about a DC clamp on meter - how much are the batteries taking at the different voltages?
Over the years repaired several PD converters most with input side caps defective. Suggest you take it out and open it up look closely at the components - normally a visual inspection quickly shows the problem area.
