A 400 kVA generator delivers approximately 320 kW of usable power — enough to run a heavy manufacturing facility with large motors and process heat. At 75% load it consumes roughly 68 litres of diesel per hour. In South Africa a 400 kVA silent diesel generator typically costs between R620 000 and R790 000 excluding VAT and installation.

Is 400 kVA the right size?
Four hundred kVA is heavy industrial territory. Provide a full motor schedule and duty cycle — soft starters and VFDs often reduce the required set size more cheaply than oversizing.
400 kVA generator FAQs
Industrial 400 kVA sets typically cost R620,000 to R790,000 excl. VAT depending on engine and canopy.
About 68 L/h at 75% load (~R1,598/h at R23.50/L).
Around 320 kW — heavy manufacturing and large process plants.
Three-phase industrial only.
Engineered civil works, often container or power-house, bulk fuel, exhaust stack, protection relays and CoC switchgear integration.
Many sites use open skids inside acoustic plant rooms; canopied units suit outdoor pads with boundary noise limits.
