Buying Guide: Key Purchase Considerations
- Power needs: Determine peak wattage versus running watts to select a generator with adequate capacity for essential loads (refrigeration, lighting, heating/cooling, medical devices) without overloading the unit.
- Fuel type and availability: Diesel engines offer better fuel efficiency and longer life for heavy-duty use, but fuel availability and storage are important. Consider dual- or tri-fuel options if you want flexibility in fuel sources.
- Run time and fuel capacity: Look for larger tanks or low-SHDT (low harmonic distortion) units that deliver steady power for longer periods between refueling.
- Durability and portability: A sturdy frame, lifting points, and vibration isolation improve field reliability. Weight and footprint affect transport to job sites or remote locations.
- Safety features: Auto shutoff on low oil, high temperature, and CO sensors contribute to safer operation, especially for unattended backup scenarios.
- Noise levels and enclosure: Enclosures with sound attenuation are beneficial for residential use and outdoor events, reducing fatigue and disturbance.
- Maintenance and serviceability: Accessible filters, oil changes, and warranty support impact long-term cost of ownership and downtime.
- Compatibility: Parallel operation options and multiple receptacle types support scalable power for evolving projects.
