Buying Guide
What to consider when choosing a tri-fuel inverter generator:
- Power needs: Match running and peak watts to your essential loads. Home backup usually benefits from higher peak and running wattage.
- Fuel flexibility: Tri-fuel capability protects against fuel shortages but check fuel-specific peak outputs and available fuel access.
- Inverter technology: Look for stable THD (total harmonic distortion) under 3-5% for sensitive electronics.
- Run time and tank size: Larger tanks provide longer runtimes between fills; consider your outage duration and fuel storage space.
- Noise level: Quieter operation improves usability in neighborhoods and campsites; verify decibel levels at representative loads.
- Safety features: CO sensors, low-oil shutdown, and GFCI outlets reduce risk during use.
- Transfer-switch readiness: If you plan to power a home circuit, ensure the model supports a transfer switch or interlock kit.
- Portability vs. capacity: Heavier units offer more power but require more handling; consider wheel kits and lifting options.
Frequently Asked Questions
- What is a tri-fuel inverter generator?
It is a portable generator that can run on gasoline, propane, or natural gas, using inverter technology to provide clean, steady power suitable for electronics.
