Buying Guide: How to Choose the Best Inverter Generator

Selecting the right inverter generator requires careful consideration of several factors beyond just wattage output. The most important consideration is determining your actual power needs by calculating the starting and running watts of all appliances you plan to operate simultaneously. Starting watts (also called surge watts) represent the extra power needed to start electric motors in appliances like air conditioners and refrigerators, while running watts represent the continuous power draw during normal operation. Always add a 20% buffer to your total calculated wattage to ensure the generator isn’t operating at maximum capacity continuously.

Noise level is another critical factor, especially if you plan to use the generator for camping or in residential areas. Inverter generators typically range from 50-75 dBA, with lower numbers indicating quieter operation. For comparison, normal conversation is about 60 dBA. Consider where you’ll be using the generator and how noise restrictions might affect your choice. The fuel type preference is also important – gasoline offers the most availability but propane burns cleaner and stores indefinitely, while dual fuel models provide the flexibility of both options.

Portability features deserve careful consideration based on how you plan to transport and store the generator. Look for wheel kits, especially on heavier models over 80 pounds, and consider whether you need electric start for easier ignition. For RV use, ensure the generator has an RV-ready TT-30R outlet or consider models with transfer switch capability for home backup installation. Safety features like carbon monoxide detection and automatic shutoff are essential, especially for overnight use or operation near living spaces.

The warranty length and customer service availability should factor into your decision, as generators are significant investments that may require service over their lifetime. Established brands typically offer 2-3 year warranties with nationwide service networks, while budget models may have shorter warranty periods and limited service options. Finally, consider the total cost of ownership including fuel consumption rates, maintenance requirements, and the availability of replacement parts and accessories.
