Buying Guide: Key Purchase Considerations
Fuel flexibility, power needs, and safety features are the core factors when choosing a 15,000-watt tri-fuel generator. Consider the following before you buy:
- Fuel availability: If natural gas is inconsistent in your area, prioritize models with propane or gasoline options as a backup.
- Transfer switch compatibility: For seamless home backup, confirm that the unit supports transfer switches (ATS) or interlock kits compatible with your electrical panel.
- Runtime and tank size: Look for larger fuel tanks if you expect long outages; this reduces refueling frequency.
- Starting options: Electric start with a robust backup (recoil or remote start) provides reliability in poor weather or cold starts.
- Safety features: CO detection or CO shutdown, low-oil shutdown, and proper enclosure design help protect occupants during operation.
- Portability vs. footprint: Tri-fuel units with high power can be heavy; plan for storage space and handling needs.
- Maintenance and parts availability: Choose brands with widely available parts and service networks for easier upkeep.
