- Portability vs. Power: Larger wattage generators are typically heavier and bulkier. Decide if you need to move the generator frequently or if it will remain in a fixed location.
- Noise Level: Inverter generators are generally quieter than traditional ones. Consider your neighbors and local noise ordinances.
- Inverter vs. Conventional: If you plan to power sensitive electronics (computers, TVs, medical equipment), an inverter generator is essential for clean, stable power.
- Starting Mechanism: Electric start and remote start offer convenience, especially in bad weather or when you need power quickly.
Frequently Asked Questions
Q: What is the main advantage of a tri-fuel generator?
A: The primary advantage of a tri-fuel generator is its incredible versatility. You can switch between gasoline, propane, and natural gas based on availability, cost, and your specific needs during an outage. This ensures you’re never without a fuel option.
Q: Are tri-fuel generators safe for sensitive electronics?
A: Not all tri-fuel generators produce clean power. Inverter generators, like the Westinghouse 8200 and 12000 Peak Watt models reviewed, are specifically designed to produce low Total Harmonic Distortion (THD) power, making them safe for sensitive electronics. Conventional generators may not offer this level of power purity.
Q: How long can I run a tri-fuel generator on a tank of gasoline?
A: Run times vary significantly based on the generator’s fuel tank size, engine efficiency, and the load it’s powering. Larger generators running at a lower percentage of their capacity will generally run longer. Always check the manufacturer’s specifications for estimated run times at 50% load.
Q: Is natural gas a good fuel option for a home backup generator?
A: Yes, natural gas is an excellent fuel option if you have a permanent connection to a natural gas line. It offers virtually unlimited runtime as long as the gas supply is uninterrupted, meaning you don’t have to worry about refueling or storing large quantities of fuel.
