Buying Guide: Key Purchase Considerations
- Power needs: Assess total wattage, including starting surges for essential appliances. Look for a generator with peak wattage that comfortably exceeds your highest load.
- Fuel options: Dual-fuel capability adds flexibility during outages when gasoline may be scarce. Propane tends to offer longer storage life but lower running watts compared to gasoline.
- Transfer switch readiness: A transfer switch simplifies connecting the generator to your home’s electrical system for safe, automatic power redirection during outages.
- Run time and fuel tank size: Larger tanks and efficient engines extend runtime. Consider your outages’ typical duration and availability of refueling.
- Safety features: CO sensors, automatic shutdown for low oil, and rubber outlet covers improve safe operation in home environments.
- Start method: Remote or electric start enhances convenience, especially in cold or rainy conditions.
- Portability vs. stationary needs: Consider the weight, wheel kits, and handle design if you must move the unit or store it compactly.
Frequently Asked Questions
- What does dual-fuel mean for a home generator?
Dual-fuel generators can run on gasoline or propane, giving you flexibility during outages or supply limits.
- Is a larger peak wattage always better?
A higher peak wattage allows handling startup surges but may consume more fuel; match it to your critical load requirements.
- Do I need a transfer switch?
A transfer switch safely connects a generator to your home circuits and prevents backfeeding, reducing risk to utility workers.
- Should I prefer gasoline or propane for run time?
Gasoline typically provides higher running watts, while propane can offer longer storage life and cleaner emissions.
- What safety features matter most?
CO detection, low-oil shutdown, and grounded outlets protect occupants and equipment during outages.
- How do I determine the right size for my home?
List essential circuits (refrigerator, furnace, lights, modem, some outlets) and sum their wattage; choose a unit with adequate peak and continuous power.
