Chances are the problem lies with the fuel supply. Your inverter is working
better, taking more power, putting more current into the batteries.
Therefore the generator, which is well within it's rating, is taking more
fuel.

You may want to check the ac voltage with a good "true RMS" meter and see what
the results are, some (most) new Freq Drives, and soft start drives may have an
issue with a high RMSJerry

ChrisA few questionsAre you drawing from both AC legs from the genny, at max of
2200 watts per leg then the genny should not have an issue but if you upsized
the batteries and as stated by Mike the fuel delivery system cant keep up
because the inverter charge load is higher, steady and for
Hi Allan,
just to add to the testimony of others, I have several customers out there
with 1990s era Trace DR inverters running SQ pumps and they seem to work fine.

Allan,
I have several customers running the Grundfos SQE series on their
modified square wave inverters.
To be clear, those most recent was about 5 years ago, so perhaps
there's been a design change since then.

You can tell the grey-beards from younger wrenches…..A square wave is generated
and modified to act like a sine wave, thus, it is a modified square wave. As I
see it, in order to deceive the consumer, the term "modified sine wave" was
created.

Allen,
I have a customer who until recently ran her SQ off of a Trace DR2412
modified sinewave inverter/charger just fine for 6 or more years. I
think some folks refer to these inverters as modified square wave.

Chris,
In theory the upgraded batteries should be able to accept a greater current
(or at least max charge current) for a greater length of time than the prior
battery bank. I once had a propane genset run rough when it was starved for
fuel, due to an undersized upright propane cylinder which coul
