What does 4000 VA mean?
Hi all, What exactly does 4000 VA mean in an autoformer? In a generator? In an inverter? Thanks in advance.

As Roger said, volt-amps, or "apparent power". It's the RMS voltage multiplied by the RMS current.
It's not quite exactly the same as watts (actual power), but much of the time the differences are not worth worrying about as a practical matter for the sorts of things RVers deal with. When the power factor is poor (less than one), the apparent power will be greater than the actual power. It cannot ever be less than the actual power, however.
