Diesel generators provide standby and prime power for homes, offices, stores, farms, construction sites and industrial plants. Diesel engines are suited to long running hours, which makes them a common choice for backup power during outages and for sites without grid power.
How to choose a diesel generator
- Size (kVA or kW): add up the wattage of what you need to run, including the higher starting load of motors, pumps and aircon units. Leave some spare capacity.
- Open or silent type: open-frame units are lighter and cost less for job sites. Silent (canopy) types, such as the Bravus DG15000BR and Ingco GSE10500-5P, reduce noise for homes and businesses.
- ATS: an automatic transfer switch, available on Bravus BDG and DG10000BR models, starts the generator and switches the load when grid power fails.
- Phase and voltage: most homes use single phase. Factories and large buildings may need three-phase power, so check the specifications before ordering.
- Welding generators: units such as the Powerhouse PHWMG-7500E and JR Kawasaki JRKDWG280AMP combine a generator with a welder for remote sites.

Diesel or gasoline generator?
Diesel generators cost more at first but suit long running hours and larger loads. Gasoline generators are lighter and cost less for occasional backup. For sensitive electronics, see inverter generators, and for quieter operation, see silent type generators. Have a licensed electrician connect any generator to your building wiring.
