Buying Guide for 50 Amp Portable Generators
Power Output and Load Capacity
To ensure your generator meets household or RV power needs, focus on the running watts and starting (peak) watts. Running watts indicate continuous power supply for regular operation, while starting watts handle initial surges from motors and compressors. For 50 amp usage, look for generators with at least 9000 running watts and a peak around 13000 watts to accommodate large appliances like air conditioners, water heaters, and multiple heavy devices simultaneously.
Fuel Type and Flexibility
Dual and tri-fuel generators offer more flexibility for fuel sourcing, allowing operation on gasoline, propane, and sometimes natural gas. Gasoline typically provides higher power and longer runtime per tank, but propane and natural gas offer cleaner combustion and easier storage. Tri-fuel models increase versatility significantly, useful in emergencies or areas with variable fuel availability.
Run Time and Fuel Tank Size
Longer run times reduce frequent refueling interruptions during outages. Generators with larger fuel tanks and efficient engines provide more hours at typical loads – usually between 8 to 19 hours on gasoline. Some models specify run time at 25% load for realistic duration expectations. Consider your typical energy demand to choose the appropriate tank capacity and expected runtime.
Starting Options and Ease of Use
Remote electric start systems enhance convenience, allowing generator activation without manual pull starts. Backup recoil start ensures functionality if battery or remote features fail. Look for models with key fobs or push-button starts, especially if frequent power interruptions are anticipated.
Outlets and Transfer Switch Compatibility
A 50 amp 120/240V outlet (14-50R) is critical for RVs and whole house connections via a transfer switch or interlock kit. Additionally, multiple 120V outlets (GFCI protected) support regular household appliances. Transfer switch readiness simplifies switching between utility and generator power for seamless backup during outages.
Noise Level and Emission Controls
Inverter technology reduces noise and provides cleaner power with less voltage fluctuation—a valuable trait for sensitive electronics. Also, check for compliance with emissions standards and features like carbon monoxide shutdown sensors to increase safety during operation.
Durability and Safety Features
Heavy-duty engines with cast iron sleeves improve lifespan and reduce wear. Automatic low oil shutdown and CO sensors protect the unit and users. Weather-resistant outlets with rubber covers add safety during outdoor use. Digital displays for voltage, frequency, and runtime assist in monitoring generator status for reliable operation.
