Overview
Homeowners who want whole-house backup get a tri-fuel generator that runs on gasoline, propane or natural gas. A heavy duty overhead valve engine drives copper windings for clean power, and a key fob starts it from a distance.
Fuel flexibility and large outlets let it power the air conditioner, fridge and sump pump through one cord to a transfer switch. Its weight means it moves on wheels only, and installation parts are extra.
Who it's for
Larger homes and job sites that need high output and fuel options in a long outage. Campers and RV travelers want a small inverter instead.
Pros and cons
- Runs on three fuels
- High running output
- Transfer switch ready outlets
- Remote electric start
- Transfer switch not included
- Natural gas hookup parts not listed
Performance notes
Output falls a step on propane and again on natural gas, so the fuel choice governs how much load it carries. Low harmonic distortion makes the power clean enough for electronics, and runtime depends on load and tank size.
