Buying Guide: How to Choose the Best Inverter Generator for Home Backup

After testing dozens of generators over the years, I have learned that choosing the right unit requires understanding your specific needs rather than simply buying the most powerful or expensive option.

Calculate Your Wattage Requirements

Start by listing essential appliances you need during an outage. A typical refrigerator draws 600-800 running watts but requires 1200-1500 starting watts when the compressor kicks on. Add up running watts for all items you will run simultaneously, then add the highest starting wattage requirement.

Most homes need 3000-5000 watts for essentials including refrigeration, lights, internet, and phone charging. Whole-house backup with air conditioning requires 7000-13000 watts depending on home size and climate.

Choose Your Fuel Type

Gasoline offers convenience and availability but degrades within 12 months without stabilizer. Propane stores indefinitely and burns cleaner but provides slightly less power. Dual fuel generators offer the best of both worlds for emergency preparedness.

Tri-fuel options adding natural gas exist for stationary installations but are overkill for portable needs. Consider propane if you already use it for grilling or heating.

Understand Noise Levels

Inverter generators typically operate between 50-65 dBA, roughly equivalent to conversation levels. Conventional generators often exceed 75 dBA, comparable to vacuum cleaners. If you have close neighbors or noise ordinances, prioritize quieter models.

Economy modes reduce noise during light loads by slowing engine speed. This feature also improves fuel efficiency significantly.

Prioritize Safety Features

Carbon monoxide poisoning kills generator users every year. Modern units include CO sensors that shut down the engine if dangerous levels accumulate. Never operate generators inside homes, garages, or enclosed spaces even with these protections.

Ground fault protection and overload circuits prevent electrical hazards. Low oil shutdown protects engines from damage during extended operation.

Consider Portability vs. Power

Higher wattage generators weigh more. The DuroMax XP13000EH at 234 pounds requires a permanent location with a cart for movement. The Pulsar PG2200BiS at 44 pounds travels anywhere but provides limited output.

Wheel kits and telescoping handles help manage heavier units. Consider who will move the generator and how far when making your selection.
