Buying Guide
- Fuel availability and fuel type: Consider whether you have reliable access to propane, natural gas, or gasoline. Tri-fuel options maximize flexibility during shortages.
- Power needs and run time: Calculate essential circuits you must power and desired runtime at a typical outage. Larger homes need higher running watts and bigger tanks.
- Transfer switch compatibility: Verify that the generator is transfer switch ready for seamless connection to your home’s electrical system.
- Safety features: Look for CO detectors, automatic shutdowns, and weatherproof outlets to protect your family and equipment.
- Portability vs. standby-style setups: Portable units offer flexibility, while higher-watt units need robust storage and ventilation.
- Maintenance and service: Consider engines with durable components, electronic start options, and hour meters for easy maintenance tracking.
FAQ
- What is the difference between running watts and peak watts? Running watts indicate continuous power available; peak watts are the surge available for startup loads.
- Is propane a good fuel for home backup? Propane offers clean burn and longer storage without degradation, making it a solid backup option when gas supply is stable.
- Do I need a transfer switch for home backup? For safe and code-compliant operation, a transfer switch or an interlock kit is recommended to connect a generator to your home wiring.
- Can I run a full home on a portable generator? Most homes require multiple units or very high-watt models; plan around essential circuits to avoid overloading.
- What safety features should I prioritize? CO detection, automatic shutdown, proper outlet covers, and weather protection improve safety during outages.
- How should I choose between dual fuel and tri-fuel? Dual fuel offers flexibility between two fuels; tri-fuel adds natural gas compatibility, increasing fuel options during emergencies.
