Generator FAQ

400 kVA — Generator FAQ

How many kW is a 400 kVA generator?

At the standard 0.8 power factor, 400 kVA equals about 320 kW of usable output. Lighting and IT loads with a higher power factor draw closer to the full kVA; motor-heavy loads draw less.

How much fuel does a 400 kVA generator use?

Roughly 50.4 litres per hour at 75 % load, and about 76.8 litres per hour at full load, depending on the engine. A base tank of about 400 litres gives eight hours of running at 75 % load; larger day tanks and bulk tanks are available.

Should I buy 400 kVA standby or prime?

If the set backs up utility power for limited hours a year, size on the standby rating. If it is your main power source — a camp, a remote site, daily use — size on the prime rating, which is about 10 % lower, so the set runs in its 70–90 % sweet spot.

What is the price of a 400 kVA generator in Saudi Arabia?

Price depends on the engine brand, enclosure (open, silent, containerized), alternator, controller and options such as ATS and fuel tanks. Send us the specification or choose a model above and we reply with a priced offer in SAR, including VAT and delivery, within 24 hours.
