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.

Hi RCMAN46,
Well, my kill-a-watt meter says 723 watts running hard. I never see 40 amps from it (37 max), and I never see 14.4 until amperage drops considerably lower than the 37 amps.
I was trying to calculate input watts which is why I divided the 0.7 into the watts of output.

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?Mandalay Parr wrote:
Actually VA times the power factor(pf) = Watts.
For practical purposes you can consider that watts is basically = to VAs
The correct answer is 40 X 14.4 X 0.7 = 403.2 watts.
