Petrol vs Diesel vs Inverter Generator
Petrol, diesel and inverter generators all give backup power, but they suit different needs.
Updated 12 November 2026
Petrol generators
The usual home backup: easy to start, easy to service and the lowest price per kVA (Petrol Generators).
Diesel generators
Use less fuel per hour and last longer on long daily runs; best for shops, offices and long load shedding (Diesel Generators).
Inverter generators
Clean, stable power for electronics and inverter ACs, quieter and more fuel-saving at low load, but cost more per kVA (Inverter Generators).
Dual fuel (petrol and gas)
Run on petrol or LPG / natural gas; gas is usually cheaper to run where it is available.
