25 kVA Generator FAQ

What can a 25 kVA generator power?

A 25 kVA generator provides about 20 kW of continuous (prime) power. It is commonly used for small jobsites, light towers, hand tools, a site office trailer, food trucks and small 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 25 kVA unit delivers about 20 kW.

How much fuel does a 25 kVA generator use?

The reference model, the Multiquip WhisperWatt DCA25SSIU4F, burns about 1.62 gallons per hour at full load and less at partial load.

How long will a 25 kVA generator run on a full tank?

With a 41.7-gallon tank, the Multiquip WhisperWatt DCA25SSIU4F runs about 25 hours at full load and considerably longer at typical partial loads.

How loud is a 25 kVA WhisperWatt generator?

Super-silent enclosed units like the Multiquip WhisperWatt DCA25SSIU4F are rated at about 65 dB(A) at 23 feet, quiet enough for residential and event work.
