Buying Guide: How To Choose A 50 Amp Propane Generator
- Power needs: Estimate total wattage of essential circuits. If you expect both high surge loads and continuous running needs, prioritize units with higher peak and running watts on propane, since propane performance is typically lower than gasoline.
- Fuel flexibility: Decide if you want dual-fuel or tri-fuel capability. Dual-fuel units offer gasoline for peak power and propane for longer outages; tri-fuel adds natural gas as an option when propane supply is limited.
- Run time: Look at tank size and efficiency. Longer runtimes on propane mean fewer fills during emergencies, but verify the running watts at those runtimes to ensure your critical appliances stay powered.
- Safety features: Prioritize CO alarms, automatic low-oil shutdown, and weatherproof outlets with rubber covers for outdoor use. Consider remote start or electric start for convenience during outages.
- Accessibility and placement: Heavier units require sturdy storage and proper ventilation. Plan for a safe transfer-switch installation to protect utility workers during outages.
