Buying Guide
What should you consider when choosing a dual fuel generator?
- Fuel availability and cost: Determine which fuels are easiest to obtain in your area and how fluctuations may affect running costs.
- Power needs: List essential appliances and calculate running watts to avoid overload. Consider peak watts for surge devices like air conditioners.
- Transfer switch readiness: A transfer switch helps switch power from the grid to the generator safely. It’s critical for seamless home backup.
- Safety features: CO sensors, automatic low-oil shutdown, and remote start can enhance safety and convenience.
- Portability vs. capacity: Larger models deliver more power but are heavier and louder. Balance mobility with wattage requirements.
- Fuel-switch logic: Some models automatically switch to a preferred fuel when available, while others require manual changes. Consider your tolerance for manual steps during outages.
- Noise levels: In residential areas, quieter models reduce disturbance. Check decibel ratings if noise is a concern.
Frequently Asked Questions
- Q: What is the advantage of a tri-fuel generator?
A: It offers the most fuel flexibility, ensuring power even if one fuel type is scarce or expensive. - Q: Do these generators require professional installation?
A: Most require a transfer switch installation by a licensed electrician for safe, code-compliant operation. - Q: Can I run a dual fuel generator indoors?
A: No. Generators emit carbon monoxide; they must be used outdoors with proper ventilation. - Q: How do I know which wattage model I need?
A: List critical appliances and sum their running watts. Choose a model with a margin above that total to handle surges. - Q: Is remote start worth it?
A: For frequent outages or hard-to-reach locations, remote start adds convenience and reduces manual handling. - Q: What maintenance is required to keep dual fuel capability?
A: Regular oil changes, air filter checks, spark plug inspection, and fuel system cleaning help maintain performance.
