Buying Guide: Key Considerations For Auto Start Home Generators
What power level do you need?
Estimate your essential loads (fridge, furnace, lights, modem, outlets) and choose a unit with higher running watts than your total load for reliable operation during outages. Consider peak watts for short surges from appliances.
Which fuels are important to you?
Gasoline provides immediate power and strong peak values. Propane offers cleaner burning and longer shelf life. Natural gas offers a continuous fuel source when plumbed to a home line, but may limit peak output. Dual or tri-fuel models give the most flexibility during emergencies.
Start method and convenience
Electric push-button start with a remote key fob is the easiest to activate during bad weather. Auto choke assists starting when conditions are not ideal. Remote or automatic transfer switch compatibility is essential for seamless integration with home circuits.
Safety features to consider
CO sensors and automatic shutdown offer added protection in enclosed spaces. Look for rubber outlet covers, low-oil shutdown, and hour meters for maintenance reminders. Carbon monoxide risk makes placement and ventilation critical.
Runtime and fuel capacity
Long runtimes are important for extended outages. Larger tanks extend operation between fill-ups, but also increase unit size. If you rely on propane for fuel, ensure supply continuity or storage strategy.
Installation and portability
Size and weight affect where you can place the unit. Consider wheeled kits, handles, and transport options for easier movement during storms or outages. If you plan to connect to a transfer switch, verify compatibility and professional installation requirements.
FAQ
- What does “auto start” mean on a generator? It means the unit can start automatically when commanded by a transfer switch or a monitoring system, often via remote or smart controls, without manual pulling.
- Is it better to choose dual-fuel or tri-fuel? Dual-fuel units offer two fuel sources; tri-fuel adds a third option (often natural gas). Tri-fuel provides more flexibility but can be heavier and more expensive.
- Do these generators support home transfer switches? Yes, most listed models are transfer switch ready or compatible with transfer switches for seamless home power transfer.
- What safety features should I expect? Look for CO sensors, automatic shutdown, and safe outlet covers to reduce risk of fumes or electrical hazards.
- How long can these run on a full tank? Runtime depends on watt load and fuel; higher watt draw reduces runtime. Always consult the specific run-time figures for the load profile you expect.
- Where should I place a backup generator? Place outdoors, away from doors and windows, with good ventilation to minimize CO exposure and heat buildup.
