How to Choose Your Tri-Fuel Generator
- Wattage Requirements: Calculate your essential and desired appliance wattage. Add up the starting (surge) watts for your largest motor-driven appliances (fridge, AC, well pump) and the running watts for all other items you want to power simultaneously. Always get a generator with more capacity than your estimated need.
- Fuel Type Versatility: While all the listed generators (except one dual-fuel) offer tri-fuel, consider which fuel sources are most accessible and cost-effective in your area. Natural gas offers continuous supply if connected, propane stores well, and gasoline is universally available but has a shorter shelf life.
- Conventional vs. Inverter: Conventional generators are generally more affordable per watt but are louder and produce “dirtier” power (higher Total Harmonic Distortion, THD). Inverter generators are quieter, produce clean power safe for sensitive electronics (laptops, TVs), but are typically more expensive per watt and have lower maximum outputs.
- Noise Level: If operating near neighbors, an RV,
