How to Choose
Size From Natural-Gas Output
It is often the lowest rating.
Verify Gas-Line Capacity
BTU delivery and pressure matter.
Plan Professional Connection
Natural-gas setup may require qualified work.
Compare Inverter vs Conventional
Power quality, noise and price differ.
Check 120/240V Outlets
Needed for many home circuits.
Do Not Assume Utility Gas Is Guaranteed
Disasters can interrupt service.
Portable Generator Safety
Frequently Asked Questions
What three fuels are supported?
Gasoline, propane and natural gas.
Which gives highest output?
Usually gasoline.
Can natural gas run indefinitely?
Only while service and maintenance remain available.
Do I need a professional?
Often for gas connection and sizing.
Are tri-fuel units portable?
They are wheeled but often extremely heavy.
Are inverter tri-fuel models worth it?
Yes when cleaner power and lower noise justify the cost.
