Buying Guide: Key Purchase Considerations
- Power needs: Estimate essential circuits and total wattage. Choose a model with a comfortable margin above your calculated load to prevent overloading.
- Fuel flexibility: Dual Fuel or Tri-Fuel units offer options during outages when one fuel source runs short.
- Run time vs. tank size: Compare gallons or liters to estimated runtime at typical loads to avoid frequent refueling.
- Transfer switch compatibility: Ensure the generator is transfer-switch ready and compatible with your home panel.
- Safety features: Look for automatic low-oil shutdown, CO sensors, and idle control to protect both equipment and occupants.
- Noise and footprint: Consider decibel levels and space requirements for placement near living areas.
- Maintenance access: Favor models with accessible air filters, spark plugs, and oil checks for easier upkeep.
Frequently Asked Questions
- Q: What does “peak watts” mean for a generator?
A: Peak watts indicate the maximum power the generator can supply for a short period, typically during startup of appliances. Running watts represent continuous output under steady load. - Q: Do tri-fuel generators run on natural gas?
A: Yes. Tri-fuel models support gasoline, propane, and natural gas, offering flexibility when power is essential. - Q: Are these generators safe for electronics?
A: Models with low THD (total harmonic distortion) below 5% are generally safer for sensitive electronics like computers and TVs. - Q: What maintenance is required for backup generators?
A: Regular oil changes, air filter checks, spark plug inspections, and battery testing (for electric start) are typical maintenance tasks. - Q: How far should I place a generator from my home?
A: Follow manufacturer guidelines and local codes, typically placing units outdoors with adequate ventilation and away from doors, windows, and populated areas. - Q: Can I install a transfer switch myself?
A: Installation usually requires a licensed electrician to ensure safety and code compliance, especially for 240V circuits.
