Buying Guide: Key Considerations When Choosing a Diesel Generator for RV Use
Selecting the right diesel (or dual fuel) generator for your RV requires evaluating a variety of factors to ensure reliable and safe power delivery tailored to your travel needs.
Fuel Type and Efficiency
- Diesel vs. Dual Fuel vs. Gasoline: Diesel generators offer high fuel efficiency and durability but can be heavier. Dual fuel models provide versatility by allowing both propane and gasoline, extending runtime options while offering cleaner fuel alternatives.
- Run Time: Consider the fuel tank size and load efficiency to maximize operating hours during extended trips without frequent refueling.
Power Output and Capacity
- Starting and Running Watts: Verify the surge (starting) watts needed to power heavy RV appliances like air conditioners or microwaves, plus the continuous running watts required for sustained use.
- Scalability: Parallel capability allows connection of two units to increase maximum power, beneficial for larger RVs or additional devices.
Noise Level and Portability
- Quiet Operation: Generators rated around 60-65 dBA provide a comfortable experience at campsites and reduce disturbance to neighbors.
- Weight and Size: Lightweight inverter models (under 50 pounds) improve portability, especially important if you plan to move or store your generator frequently.
Safety Features
- CO Shutdown Sensors: Carbon monoxide detectors automatically turn off the generator to prevent harmful emissions, an essential safety feature for enclosed or semi-enclosed areas.
- Fuel Shutoff and Transfer Switches: These allow safer handling and integration with your RV’s electrical system, aiding in smooth transitions between power sources.
Additional Functionalities
- Electric and Remote Start: Enhances convenience by enabling easy generator startup without manual effort.
- Clean Power Output: Inverter technology provides stable electricity safe for sensitive electronics commonly used in RVs.
- Multiple Outlets: Access to various plug types including dedicated RV outlets simplifies connecting a wide range of devices.
