Buying Guide
Key considerations when choosing a tri-fuel generator for home use:
- Fuel flexibility: Confirm the unit truly supports gasoline, propane, and natural gas with straightforward fuel switching.
- Power needs: Estimate total running watts for essential appliances (AC, sump pump, refrigerator, lights). Choose a unit with adequate surge capacity for startup loads.
- Transfer switch readiness: If you plan a transfer switch, verify compatibility and outlet configurations (50A, 30A, RV-ready).
- Starting method: Remote electric start is convenient for frequent outages; consider models with key fob or push-button start.
- Run time and tank size: Compare hours at typical loads; natural gas connections can improve run time for continuous outages.
- Safety features: Look for automatic low-oil shutdown, CO alarms, and CO sensors to protect occupants.
- Noise and footprint: Large tri-fuel units can be loud and heavy; plan for storage and ventilation.
- Maintenance: Check service intervals, oil type, and filter accessibility to sustain long-term performance.
