How to Choose Best Propane Generators for Home Backup
Power Output Requirements
Calculate your home’s essential power needs before choosing a generator. Add up the wattage of appliances you must keep running during outages.
Refrigerators typically need 700-1200 watts, while central AC systems require 3000-5000 watts. A 10,000-watt generator handles most medium-sized homes comfortably.
Fuel Type Flexibility
Tri-fuel generators offer the most versatility with gasoline, propane, and natural gas options. This flexibility ensures you can run your generator regardless of fuel availability.
Propane stores indefinitely without degrading, making it ideal for emergency preparedness. Natural gas connection eliminates refueling entirely if you have municipal gas service.
Runtime and Fuel Capacity
Longer runtime means fewer refueling interruptions during extended outages. Look for generators offering at least 10-12 hours on a single tank.
Larger fuel tanks provide extended runtime but increase overall weight. Consider how often you’re willing to refuel versus portability needs.
Safety Features
CO shutdown sensors automatically turn off the generator when dangerous carbon monoxide levels are detected. This critical safety feature protects your family from invisible threats.
Low oil shutdown prevents engine damage by stopping operation when oil levels drop too low. GFCI outlets protect against electrical shocks in wet conditions.
Transfer Switch Compatibility
Transfer switch ready outlets allow professional installation for whole-home backup power. The L14-30R or 50-amp outlets connect directly to your home’s electrical panel.
Professional transfer switch installation costs $500-1500 but provides seamless power switching. This setup eliminates dangerous backfeeding and simplifies generator use during outages.
Frequently Asked Questions
How long does propane last in a generator?
A 20-pound propane tank typically runs a 10,000-watt generator for 7-10 hours at 50% load. Larger 100-pound tanks provide 35-50 hours of runtime under similar conditions.
Can I run my whole house on a propane generator?
Yes, generators with 10,000+ watts can power most essential home circuits including refrigerators, lights, and some HVAC systems. Larger 13,000-watt models handle whole-home backup including central air conditioning.
Is propane cheaper than gasoline for generators?
Propane typically costs less per gallon than gasoline and burns cleaner with less maintenance. However, propane produces about 10% less power than gasoline in the same generator.
Do propane generators need special maintenance?
Propane generators require less maintenance than gasoline models because propane burns cleaner. You still need regular oil changes, spark plug replacements, and air filter cleaning according to manufacturer schedules.
Can I connect my propane generator to my home’s natural gas line?
Only tri-fuel generators designed for natural gas can connect to home gas lines. This requires professional installation with proper pressure regulation and safety shutoffs.
Final Thoughts
The Westinghouse 12500 Peak Watt Tri-Fuel offers the best overall value with three fuel options and remote start at $861.75. For maximum power, the DuroMax XP13000EH delivers 13,000 watts with all-metal construction.
