Hmmm...these days, there are boost regulators (step up) and buck
regulators (step down) and even buck/boost regulators, that can
produce a set voltage from a source that goes from higher to lower
than the target voltage.
And this leads to high efficiencies too.
I imagine an inverter system could have similar qualities.

Brian Whatcott Altus OK

I've never heard of a buck, boost, or buck/boost regulator. There are
bucking, boosting and buck/boost transformers, but if the voltage is
boosted, it is at the expense of a corresponding same percentage loss of
available current, plus transformer loss.

Beat me to it.
