Buying Guide
Key considerations when choosing a dual fuel inverter generator:
- Power needs: Estimate starting and running watts for devices and appliances you plan to run. Higher surge watts help with motor startup loads.
- Fuel flexibility: Dual-fuel models offer gasoline or propane, which can extend run times during an outage or when gas stations are scarce.
- Portability: Weigh and size matter for transport and storage. Lighter units are easier to carry but may offer less power.
- Noise level: Inverter generators are generally quieter. Consider campground and neighborhood rules when selecting decibel ratings.
- Electronics safety: Look for clean power with low total harmonic distortion (THD) to protect sensitive devices.
- Safety features: CO detectors, auto shutoff, and proper ventilation are important for indoor or shelter use.
- RV and EV readiness: If you need to support RV systems or Level 2 charging, check voltage configuration and plug compatibility.
- Maintenance and warranties: Consider ease of start, oil changes, and any included warranty or service plan.
Frequently Asked Questions
- What does surge watts mean? Surge watts handle brief power spikes when appliances start, like air conditioners and motors.
- Do dual-fuel generators run on propane? Yes, most can switch between gasoline and propane, offering flexible fuel options.
- Is inverter power safer for electronics? Yes, inverters provide cleaner power with low THD, reducing risk to sensitive devices.
- How quiet should my generator be? Quiet operation is typically in the 60–65 dBA range at a standard distance; check local regulations.
- Can I parallel two generators? Some models support parallel kits to increase total available power; verify compatibility with your unit.
- Is CO safety important indoors? Yes, CO sensors and auto shutoff reduce risk in enclosed or semi-enclosed spaces.
