How to Choose the Right Diesel Generator

Power Output and Runtime

The most critical factor is matching the generator’s output to your power needs. Calculate the starting and running watts of the appliances you must keep on during an outage. For whole-home backup, look for models with a 50-amp outlet and high running wattage, often 9000 watts or more. Equally important is runtime; a large fuel tank combined with an eco-mode can provide over 15 hours of power, letting you sleep through the night without refueling.

Fuel Type and Flexibility

Modern generators offer impressive fuel flexibility. Dual-fuel units run on gasoline or propane, giving you options based on availability and cost. Tri-fuel models add natural gas, providing a nearly endless supply if you have a home hookup. This flexibility is a major advantage for long-term outages, as confirmed by users who value having multiple fuel sources. Explore all our diesel generator reviews on our category page.

Noise Level and Portability

Generator noise is measured in decibels (dBA). Quieter operation, often between 60-70 dBA, is essential for neighborhood harmony and your peace of mind, especially during overnight use. Inverter technology is key here, providing clean power while significantly reducing noise. Consider weight and wheel kits for portability if you plan to move the unit between a garage and a job site or for RV travel.

Safety and Convenience Features

Never compromise on safety. A carbon monoxide (CO) shutoff sensor is non-negotiable for indoor air safety. Look for low-THD (Total Harmonic Distortion) ratings, typically under 3%, to protect sensitive electronics like laptops and medical devices. Convenience features like electric remote start, a digital display for monitoring output, and GFCI-protected outlets add significant value and ease of use.
