Buying Guide: Key Purchase Considerations
- Fuel Flexibility: Tri-fuel capability is beneficial for price and fuel availability. Confirm the engine type and fuel delivery system compatibility with your home’s plumbing or storage setup.
- Power Output and Run Time: Evaluate peak and running watts for your critical appliances. Consider your expected run times on your primary fuel and the availability of extra fuel or gas lines.
- Transfer Switch Readiness: A transfer switch-ready generator simplifies seamless cycling of circuits during outages. Verify outlet types (L14-30R, 14-50R, TT-30R) and the presence of a dedicated RV outlet if needed.
- Remote Start and Convenience: Remote electric start saves time during outages. Check battery life, starter reliability, and compatibility with your generator’s fuel type.
- Safety Features: Look for CO sensors or shutdowns, rubber outlet covers, and robust hour meters to monitor maintenance intervals and oil levels.
- Noise and Fuel Efficiency: Inverter-based tri-fuel models tend to be quieter and more fuel-efficient but may come at higher upfront costs. Weigh noise thresholds (dBA) against runtime needs.
- Portability vs. Installation: Wheel kits and handles improve mobility, but consider the space required for fuel storage and ventilation in semi-permanent setups.
- Maintenance and Service: Choose brands with established support networks and easy-to-find replacement parts. A long-term warranty can vary by model and fuel type.
- Electrical Safety: Ensure proper grounding, CO monitoring, and compliance with local electrical codes when using a transfer switch and long power runs.
