Buying Guide
- Fuel flexibility: Dual-fuel models offer gasoline or propane options. Consider how you typically refuel and the availability of propane in your area.
- Power needs: Match peak watts to your essential loads. For homes, aim higher than the sum of your critical circuits; for RV use, prioritize outlets and RV readiness.
- Outlets and transfer readiness: If you have a transfer switch, ensure the generator has compatible receptacles (L14-30, 14-50, etc.). Look for rubber outlet covers for weather protection.
- Runtime and fuel capacity: Bigger tanks provide longer runtimes, but also add weight and size. Consider your typical outage duration and the likelihood of refueling.
- Noise and footprint: In residential areas, quieter models (under 75 dB at distance) and compact footprints are advantageous for neighbor relations and portability.
- Safety features: CO sensors, automatic shutdown on low oil, and proper ventilation are essential for long-term safe operation.
- Maintenance: Some models include tool kits and funnels, but plan for routine oil checks, air filter cleaning, and spark plug care.
FAQ
What is the difference between peak watts and running watts?
Peak watts indicate the maximum surge the generator can handle for a short period, such as starting a motor. Running watts show the continuous power the generator can supply.
Is dual fuel safe for home use?
Yes, when operated according to the manual and in a well-ventilated area. Gasoline and propane provide alternative fueling options and can improve availability during outages.
Do I need a transfer switch?
A transfer switch safely isolates home circuits from the grid and is recommended for backup power to prevent backfeeding and ensure safe power transfer.
How loud are these generators?
Noise varies by model. Some are designed for residential use with lower decibel levels, while others may be louder but offer higher power. Check the product specs for dB ratings.
What maintenance should I perform regularly?
Regular oil checks, air filter cleaning, spark plug inspection, and battery maintenance (for electric start models) help ensure reliable operation in emergencies.
