Buying Guide For 50 Amp Inverter Generators
Wattage and Power Output
Ensure the generator provides both sufficient running watts and surge watts for your power needs. Many 50 amp generators offer running watts between 6000 and 9000+, with peak wattage up to 11000 or more. Consider your devices’ startup power requirements and continuous power draw.
Fuel Type and Efficiency
Dual or tri-fuel capability adds flexibility by allowing gasoline, propane, and sometimes natural gas use. Propane and natural gas tend to be cleaner fuels. Look for generators with an Eco Mode or fuel-saving technology to extend runtime and reduce costs.
Noise Level
Inverter generators are generally quieter than traditional models. Look for noise levels below 65 dBA to avoid disturbances, especially for camping, RV use, or residential backup.
Portability Features
Weight and mobility features like telescopic handles and wheels support portability. This can be important if you plan to move the generator frequently or use it at remote sites.
Start Options and Controls
Remote electric start adds convenience, especially when the generator is housed in difficult-to-reach locations. Multiple start options, including push-button, key fob, or recoil, offer operational flexibility.
Outlets and Connectivity
Look for 50A outlets compatible with RV or home transfer switches. Multiple household outlets, USB ports, and transfer switch readiness enhance functionality in different scenarios.
Safety Features
A built-in carbon monoxide sensor with automatic shutdown can protect against harmful gas buildup. Low oil shutoff and overload protection extend the generator’s life and improve user safety.
Power Quality
Low Total Harmonic Distortion (THD under 3%) ensures safe power for sensitive electronics such as computers, televisions, and medical devices. Pure sine wave output is ideal.
Brand Reputation and Support
Choose reputable brands known for quality and customer support. Warranty terms, availability of parts, and adaptive features like automatic transfer switch compatibility are advantageous.
