Buying Guide for Whole House Electric Generators
Choosing the right whole house generator depends on several key factors:
- Power Output: Calculate the wattage needed for critical appliances and systems to determine the minimum wattage capacity. Generators ranging from 10,000 watts to over 20,000 watts will power typical homes, but more extensive homes may require larger units.
- Fuel Type: Consider fuel availability—gasoline, propane, natural gas, or tri-fuel options offer varying convenience and cost. Propane and natural gas generally provide cleaner emissions and longer storage life.
- Start Mechanism: Electric or remote electric start provides ease and safety, especially during emergencies.
- Transfer Switch Compatibility: A compatible transfer switch is essential for safe home connection and operation, ensuring power routes correctly from the generator to household circuits.
- Run Time and Fuel Tank Capacity: Longer run times with larger tanks reduce the need for frequent refueling, important during extended outages.
- Safety Features: Look for CO detectors, low oil shutdown, and GFCI outlets to protect users and equipment.
- Portability vs. Standby: Portable generators offer flexibility to move them, while standby units provide automatic power restoration and are permanently installed.
- Noise Level: Consider noise output for residential use; inverter generators tend to be quieter but may not meet whole house power requirements.
- Warranty and Support: Choose reputable brands with solid warranties and accessible customer service for peace of mind and long-term reliability.
