Buying Guide: How To Choose Your Inverter Generator
What size do you need?
Determine your essential load in watts. Create a list of devices you’ll power, including starting wattage for motors. Choose a generator with a surge watt rating comfortably above your total startup needs.
Fuel type matters
Gasoline is common and quick to refuel, but propane and dual-fuel options can extend runtimes when gasoline isn’t available. Consider fuel availability and storage in your typical use area.
Power quality and electronics safety
Look for inverter technology that produces a clean sine wave with less than 3% total harmonic distortion (THD). This protects sensitive electronics like laptops, CPAP machines, and cameras.
Noise and portability
Noise levels are important for camping and quiet neighborhoods. Check dB ratings at a standard distance (often 7–23 feet). Also weigh weight and wheel options if you’ll move the unit frequently.
Run time and fuel efficiency
Runtime depends on load and fuel tank size. Inverter units with Eco or Smart modes adjust engine speed to save fuel, extending runtimes for typical loads.
Safety features
CO shutdown sensors, proper grounding, and a bonded-neutral configuration (where applicable) are important for safety and compatibility with charging and vehicle systems.
FAQ
- What is an inverter generator? A: An inverter generator converts AC to DC, then back to a clean AC waveform, delivering stable, high-quality power ideal for sensitive electronics.
- Do I need dual-fuel capability? A: Dual-fuel provides flexibility when one fuel source is scarce or expensive, which can be advantageous for long outages or remote camping.
- Is 50% load or 25% load better for efficiency? A: Running closer to but not at full load with Eco mode typically yields better fuel efficiency and quieter operation.
- How loud are inverter generators? A: Noise varies by model; many portable units range from 52 dB to 70 dB at typical distances. Check the spec for your preferred use environment.
- Can these generators run appliances like air conditioners? A: Some high-watt units can start and run A/C units, but you should verify surge watts and continuous running watts to prevent overload.
- What maintenance is required? A: Regular oil changes, spark plug checks, and air filter cleaning are typical. Always follow the manufacturer’s maintenance schedule.
