Buying Guide
Power requirements: Assess essential loads—refrigeration, sump pumps, heating, lighting, and entertainment. Choose a unit that provides more than your calculated running watts to avoid overloads during startup surges.
Fuel versatility: Dual-fuel options offer resilience by enabling gasoline or propane. This is valuable during fuel shortages or supply chain disruptions common after storms or outages.
Transfer switch compatibility: If you plan to connect to a home panel, ensure the generator supports a compatible transfer switch and that installation follows electrical codes and safety standards.
Runtime and tank size: Larger fuel tanks extend runtime between refills, particularly for long outages. For mobile use, a compact, efficient unit with longer run times is beneficial for RV or campsite scenarios.
Safety features: CO sensors, automatic shutdown, wheel kits, and proper outlet covers reduce risk. Inverter generators offer cleaner power with lower THD, ideal for sensitive electronics.
Portability vs. power: If you need frequent relocation, consider units with wheels and ergonomic handles. If your priority is maximum power for a home, a larger dual-fuel model with a transfer switch is suitable.
Noise and climate: Inverter models tend to be quieter and better suited for residential settings, while traditional generators may deliver more raw power for higher-demand scenarios. Consider climate and noise restrictions at your site.
Maintenance: Look at service intervals, accessibility of spark plugs, oil changes, and availability of replacement parts. A longer warranty can provide peace of mind for critical backup systems.
