Buying Guide: How To Choose The Right Inverter Generator
- Power needs: Match surge and running watts to the appliances you plan to run. Higher surge watts benefit air conditioners and power tools at startup.
- Fuel type and efficiency: Gasoline provides quick refueling options; dual-fuel units offer flexibility. ECO or smart modes increase runtime efficiency.
- Portability vs. output: Balance weight, size, and handles with the wattage you require. Open-frame designs may need extra protection from the elements.
- RV readiness and outlets: If you plan to feed RV plugs or Level 2 charging, ensure the correct outlets (RV 30A, 120V, or 240V) are available.
- Safety features: Look for CO shutoff sensors, low-oil shutoffs, and proper grounding or bonded neutrals for sensitive electronics.
- Runtime and fuel capacity: Larger tanks extend runtime but add weight. Consider expected outage duration and refueling options.
FAQs
- What does inverter wattage mean for my appliances? Inverter watts indicate the sustained power available to operate devices; surge watts handle startup spikes.
- Is dual-fuel worth it for home backup? Dual-fuel units offer flexibility with different fuel sources and can be useful when fuel supplies are limited.
- Should I choose a larger inverter than I think I need? If you plan to use heavy appliances, a model with higher running watts reduces risk of overload.
- What noise level is typical for inverter generators? Many portable inverters operate around 50-60 dB at close range; quiet models target the lower end of this range.
- Do I need CO sensors on my generator? CO sensors enhance safety, especially for indoor or poorly ventilated areas.
- How important is run time? Longer runtimes reduce refueling interruptions, important for camping and outage scenarios.
