125 kVA Generator FAQ

What can a 125 kVA generator power?

A 125 kVA generator provides about 100 kW of continuous (prime) power. It is commonly used for large jobsites, temporary power for commercial buildings, emergency backup and large events. Size it by adding the running watts of everything you will connect plus the starting surge of the largest motor.

What is the difference between kVA and kW on a generator?

kVA is apparent power and kW is real power. Mobile three-phase generators are rated at a 0.8 power factor, so kW = kVA × 0.8: a 125 kVA unit delivers about 100 kW.

How much fuel does a 125 kVA generator use?

The reference model, the Multiquip WhisperWatt DCA125SSIU4F, burns about 7.11 gallons per hour at full load and less at partial load.

How long will a 125 kVA generator run on a full tank?

With a 169-gallon tank, the Multiquip WhisperWatt DCA125SSIU4F runs about 24 hours at full load and considerably longer at typical partial loads.

How loud is a 125 kVA WhisperWatt generator?

Super-silent enclosed units like the Multiquip WhisperWatt DCA125SSIU4F are rated at about 66 dB(A) at 23 feet, quiet enough for residential and event work.
