Buying Guide: Key Considerations When Choosing A Diesel Generator
- Power needs: Match the generator’s continuous watts to the essential equipment you plan to run. Consider surge wattage for startup loads on motors and compressors.
- Fuel capacity and runtime: Larger tanks extend runtime, but weight and space matter. Balance fuel capacity with fuel availability and refueling needs.
- Durability and build: Look for steel frames, protective enclosures, and vibration isolation for harsh environments and long service life.
- Control options: Auto/Manual start, remote start capability, and user-friendly panels help simplify operation in emergencies or job sites.
- Emissions and compliance: CARB/EPA compliance may be important depending on your location and intended use.
- Portability vs. power: Portable inverter models excel in travel and quiet operation, while larger non-inverter models deliver higher continuous power for fixed setups.
- Noise levels: Consider enclosure design and sound attenuation if you’ll operate near homes, RVs, or quiet work zones.
- Safety features: Look for low-oil shutdown, overheating protection, fuel gauges, and circuit protection to prevent damage and injuries.
- Maintenance access: Easy access to air filters, oil, and fuel systems reduces downtime and cost over the generator’s life.
- Warranty and support: A solid warranty and accessible customer support can reduce long-term ownership risk.
