I never, in 40 years of fixing everything, ever found a dead cell in a new battery.

That wasn’t my intent. I see now that the included quote could be viewed as you stating “bad cells” as a possible culprit, which you never said. My apologies, I should not have included the full quote.

Why not start the generator and see if the microwave works? That would point you to the microwave or the inverter based on the result of the test.

MICROWAVE---and everything else works (and has always worked) properly with generator or shore power.
NOW---110 volt lights and tv sets work with inverter, but microwave is not happy. This is a new issue.
BATTERIES---are wired per the Alpine diagrams and seem to be holding a charge and coping with a normal DC load as you would expect.
GFCI--- in bathroom buzzes when using inverter. That seems like another sign of low voltage.

You might be upgrading to those lithium batteries sooner than you planned
