Buying Guide
- Power needs and peak vs running watts: Determine your essential appliances and choose a model with enough running watts plus sufficient peak watts for startup surges.
- Fuel options and availability: Decide between gasoline, propane, natural gas, or dual-fuel. Propane stores well and is cleaner, but availability matters during outages.
- Noise and portability: If you camp or live near neighbors, consider low-THD and quieter models. Weight and size affect transport and storage at home.
- Safety features: Look for CO shutoff, low-oil and overload protection, and data displays to monitor runtime and load.
- Home backup compatibility: For real home backup, check transfer switch readiness and whether the unit can be connected to a home electrical system or parallel kits.
- Budget and expandability: Plan for future needs; some units support additional parallel units to increase total output.
Frequently asked questions
- What makes an inverter generator more reliable? Inverter generators with solid build, consistent power output, and safety features tend to be more reliable for sensitive electronics and long runtimes.
- Do tri-fuel generators offer real benefits? Yes, tri-fuel units provide flexibility to use different fuel sources based on availability and cost, which can improve reliability during outages.
- Is higher wattage always better for reliability? Not always. Choose wattage that matches your typical load plus startup surges; excess power can increase fuel usage and noise without added reliability.
- Should I choose dual fuel or single fuel? Dual-fuel offers versatility, but ensure you have easy access to both fuel types and understand any maintenance implications.
- How important is CO safety in a generator? Very important. Generators should have CO sensors or shutoffs to prevent carbon monoxide buildup during operation.
- Can I run a generator indoors or in a garage? No. Always operate outdoors in a well-ventilated area to avoid dangerous gas buildup.
