Buying Guide
What is your total wattage need? List essential appliances and HVAC to estimate running watts. Consider peak watts for startup loads. Choose tri-fuel if fuel flexibility is a priority, or dual fuel if you primarily rely on gasoline and propane. Check transfer-switch compatibility to simplify connecting to your home’s electrical panel. Evaluate noise levels, especially for neighborhood settings. Consider runtime on your preferred fuel source and the size of the fuel tank. Remote start and CO detection add safety and convenience—prioritize models with these features if you’ll operate during emergencies. Vibration, portability, and engine size impact setup and storage.
FAQ
- What does tri-fuel mean for a generator?
Tri-fuel generators can run on gasoline, propane, or natural gas, offering flexibility during fuel shortages or outages.
- Is CO detection important on a generator?
Yes. CO sensors shut down the engine if carbon monoxide levels become dangerous, protecting occupants.
- Should I choose a transfer-switch-ready generator?
If you want seamless connection to your home’s electrical panel, a transfer-switch-ready model simplifies power restoration after outages.
- What is runtime and why does it vary by fuel?
Run time depends on fuel type, load, and tank size; propane and natural gas often provide longer runtimes with steady pressures but different energy densities than gasoline.
- How do I know which wattage to pick?
Calculate running watts for essential circuits and add peak watts to account for startup surges. Choose a unit with a buffer above your calculated needs.
- Are inverter generators safer for electronics?
Inverters provide stable, clean power with low total harmonic distortion, making them safer for sensitive electronics.
