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.

In the case of my PD 40 amp converter PF is 0.7 so 40 amps x 14.4 volts / 0.7 = 823 watts.
Is that correct?
40 amps * 14.4 volts = 576 watts DC output
576 watts DC output / 0.8 converter efficiency = 720 watts AC input needed
720 watts / 0.7 PF = 1029 VA AC input needed
Wonder how many different answers you'll get? I'm certainly not beyond making errors.
