Buying Guide: Key Purchase Considerations
Power needs and load profiles
Estimate the running watts for essential circuits, HVAC, refrigeration, and lighting. Consider peak watts for startup surges from air conditioners or motor-driven appliances. A unit with both high running watts and robust peak watts provides headroom for concurrent loads without overloading the generator.
Fuel versatility and availability
Dual-fuel or tri-fuel options offer flexibility when fuel supplies are limited. Propane and natural gas can be cleaner or more readily available in some regions, while gasoline delivers the best runtime per tank.
Safety features
CO sensors, automatic low-oil shutdown, and enhanced outlets with rubber covers improve safety. Look for transfer-switch readiness to simplify connecting to home electrical systems and avoid backfeeding.
Power quality and electronics protection
Inverter-based models with low total harmonic distortion (THD) protect sensitive devices like computers and medical equipment. If electronics safety matters, prioritize pure sine wave output and consistent voltage regulation.
Ease of use and maintenance
Remote electric start and key fob convenience save effort during outages. Digital hour meters and built-in fuel gauges streamline maintenance planning. Long runtimes reduce the frequency of refueling in critical periods.
Portability vs. stationary needs
Portable units offer flexibility for travel and job sites, while transfer switch-ready units integrate more seamlessly with home backup systems. Assess noise levels, weight, and ease of storage when selecting a model for residential use.
Warranty and support
Check manufacturer coverage, service networks, and availability of replacement parts. Reliability and long-term serviceability are vital for devices intended to run during extended outages.
