Standby vs Prime vs Continuous Power
Standby: outages only, ≤200 h/year, no overload. Prime: unlimited hours at variable load, typically 10% overload 1 h in 12. Continuous: constant load.

Fuel
How to Calculate Generator Fuel Consumption
A diesel generator burns about 0.28 L per kWh at full load: 100 kVA ≈ 22 L/h, 250 kVA ≈ 56 L/h. Part-load figures, tank runtime and monthly fuel examples.
Sizing a Generator Fuel Tank
Tank volume = L/h × target hours ÷ 0.85. Example: 500 kVA at 75% load for 24 hours needs about 2,370 litres. Base tank, day tank and main storage.
