Buying Guide: Key Purchase Considerations
What size generator do I need? Start with your essential loads, such as refrigeration, heating, and lighting. A 5–8 kW unit covers basic essentials, while 10–20 kW models support more circuits. For whole-home coverage, consider standby generators with automatic transfer switches and weather-resistant enclosures.
Portable vs. standby. Portable models (like most dual-fuel units listed) offer flexibility and lower upfront costs but require manual setup and fuel management. Standby generators provide automatic operation and continuous protection but involve higher installation costs and permanent installation requirements.
Fuel options. Dual-fuel and tri-fuel generators increase flexibility during fuel shortages but can be heavier and more complex. Gasoline offers quick power, propane provides cleaner emissions, and natural gas can enable long-term operation with a fixed supply.
Safety features. Look for automatic low-oil shutdown, CO detection, and weather-rated enclosures. Remote start is convenient but consider battery reliability and maintenance needs.
Monitoring and maintenance. Cellular or WiFi monitoring helps you stay informed on performance and maintenance needs. Routine oil changes, air filter checks, and carburetor upkeep are essential for reliability during emergencies.
Frequently Asked Questions
- Do I need a transfer switch for a generator? A transfer switch isolates circuits from the main panel, preventing backfeeding and enabling safe power transfer during outages.
- What size generator is best for a small home? For essential circuits (refrigeration, lights, some outlets), a 5–8 kW unit often suffices. For broader coverage, 10–20 kW is typical.
- Is dual-fuel worth it? Dual-fuel adds flexibility and longer runtime, especially when one fuel source is scarce; it can be heavier and more complex to service.
- Should I choose portable or standby? Portable units are affordable and flexible; standby units offer automatic operation and seamless power during outages but require installation.
- How important is CO safety? CO detectors and automatic shutdowns reduce risk from dangerous fumes, particularly indoors or in enclosed spaces.
- What maintenance is required? Regular oil changes, spark plug checks, air filter cleaning, and battery tests for electric-start units are common maintenance tasks.
