Portable Diesel Generators

Diesel generators are a go-to for job sites, remote properties, caravans, and camping where mains power isn't an option. They run longer per tank than petrol units, handle heavy loads like compressors and power tools, and cope better with extended continuous use - which is why tradies and grey nomads alike favour them.

True Gear stocks Gentech and Macfarlane Generators diesel units. Gentech runs Yanmar engines - a proven workhorse in Australian conditions - and Macfarlane covers premium inverter and AVR options for RV and remote-site use.

For a caravan with air con, a 6-8kVA diesel unit is usually the sweet spot. If you're just running a fridge, lights, and phone chargers, a smaller unit does the job. For tools on a job site or a homestead with bigger loads, look at 8kVA and up. Check your total wattage draw before you buy.

Prices vary a fair bit depending on output and quality. The diesel generators at True Gear range from around $6,900 for a solid Gentech Yanmar 6.8kVA up to $20,999 for a premium Macfarlane 8kVA AVR unit. Diesel generators cost more upfront than petrol equivalents but the fuel efficiency and engine longevity tend to make up for it over time.

A standard (open frame) diesel generator runs at a fixed RPM and is built for raw power output - great for job sites and heavy-duty applications. An inverter generator throttles the engine to match the load, which means quieter operation, better fuel economy, and cleaner power output that's safe for sensitive electronics like laptops and medical gear. If you're running a caravan or need quiet overnight power, an inverter unit is worth the extra cost.
