What is the generator voltage like when directly connected to increasing loads rather than to the inverter-charger? If it behaves sensibly then there must be some sort of feedback coming from the inverter-charger that the AVR sensor circuit is seeing and causing it to overcompensate. If this proves to be the case then maybe a filtering circuit is needed?

What is the generator voltage like when directly connected to increasing loads rather than to the inverter-charger? If it behaves sensibly then there must be some sort of feedback or harmonics coming from the inverter-charger that the AVR sensor circuit is seeing and causing it to overcompensate. If this proves to be the case then maybe a filtering circuit is needed? Or perhaps the inverter-charger is a leading power factor device and this is causing the problem - this paper offers a clue: https://www.fieldlines.com/index.php?topic=147381.0 If so then maybe power factor corrections is needed?
Have you contacted Vectron?

What
I posted an answer on this last night and then woke up thinking "Oh no! That doesn't make
sense!" so here goes again in the spirit of trying to help. . Is the AVR a separate box - one of
the clickety-click types on the market there or
is
it more sophisticated? . How does
the generator
behave when loaded by a more straightforward resistive kind of load like a heating element when
the AVR (if a separate item) is not in the loop? Put a couple of different resistive loads on it
and check the
voltage
like when directly connected to increasing loads rather than to the inverter-charger? If it
behaves sensibly then there must be some sort of feedback
and frequency. Why do you need an AVR if using a small generator
or
harmonics
do you sometimes have mains power that is unreliable? . Have you checked the voltage and
frequency
coming from the
inverter-charger
generator? (I was under what may be a false belief
that
the AVR sensor circuit is seeing and causing it to overcompensate. If this proves
these small portable generators used speed regulation to maintain voltage so if you see a
frequency rise on increasing load I would suspect the generator speed regulation
to be
the case then maybe a filtering circuit is needed? Or perhaps the inverter-charger is a leading
power factor device and this is causing the problem - this paper offers a clue:
https://www.fieldlines.com/index.php?topic=147381.0 If so then maybe power factor corrections is
needed?
Have you contacted Vectron? at fault.)
