kVA = Watts / PF
kW = kVA x PF
VA (or volt-amps)
PF(Power Factor)
For computer power supplies and other supplies that are power factor corrected the power factor is usually over 90%. For high power motors under heavy load the power factor can be as low as 35%.
Industry standard rule-of-thumb is that you plan for a power factor of 60%, which is an industry average power factor. You can determine this exactly if you have the specs on all your gear, otherwise use the industry rule-of-thumb.
For example, if the power factor is 0.6 ...
30 kW = 50 kVA x 0.6 PF

Wattage depends on the powerfactor.Observe the name board details of the generator.

Keep it simple for this guy:
50KVA x .778 (power factor) = 38,900 watts
Round it off to 39,000 watts.
by the way, if you want to buy one, I can get you one fairly cheaper then most.
