Buying Guide: Choosing Your Standby Generator
Power Output and Fuel Type
The generator’s wattage must match your home’s needs. Calculate the combined starting and running watts of the appliances you need to back up. Models like the Champion 12.5-kW Home Standby Generator offer robust power for essentials and major systems.
Consider whether you prefer a system that runs on natural gas or liquid propane (LP). Natural gas offers a continuous supply, while LP requires a tank. Our review of the best Champion dual-fuel generators provides insight into flexible fuel options for portable units.
Automatic Transfer Switch (ATS) Capacity
The ATS is the brain of the system. Its amperage rating and number of circuits determine how much of your home it can power. A 100-amp switch is common for whole-house coverage, allowing you to select critical circuits for backup.
Look for an outdoor-rated enclosure for durability. The transfer should be seamless, with minimal delay before your home’s power is restored. This is a critical component for true automatic operation.
Noise Level and Installation
Standby generators run for extended periods. A quiet model, operating around 63 dBA like the Champion unit we reviewed, is considerate of your family and neighbors. Sound-dampening technology makes a significant difference.
Professional installation by a licensed electrician is mandatory for safety and compliance with local codes. Factor this into your planning. The installation process involves connecting the generator to your fuel line and electrical panel via the ATS.
Warranty and Smart Features
A strong warranty reflects the manufacturer’s confidence. Champion offers a notable 10-year limited warranty with lifetime support. Generac provides a 5-year warranty. This long-term assurance protects your investment.
Modern generators offer smart monitoring. Features like Generac’s Mobile Link allow remote status checks. Honeywell’s Sync Controller provides maintenance tracking. These features add convenience and proactive maintenance capability. For powerful alternatives, see our list of top Champion 12,000-watt generators.
Final Thoughts
Selecting the right standby generator is about balancing power, reliability, and smart features for your specific home. For those prioritizing robust automatic whole-home backup, the Champion 12.5-kW Home Standby Generator with its excellent warranty is a compelling choice. If remote monitoring and premium engineering are your top criteria, the Generac Guardian 10kW Home Generator offers proven performance and connectivity. Either system will provide the automatic security and comfort your household deserves when the grid fails.
Frequently Asked Questions
What is the main advantage of a standby generator over a portable one?
A standby generator provides automatic, hands-free backup power. It is permanently installed and connected to your home’s fuel and electrical systems. When utility power fails, it starts automatically within seconds and powers pre-selected circuits without any action required from you, even if you are not home.
How do I know what size standby generator I need?
You need to calculate the total wattage of the appliances and systems you want to power during an outage. Focus on essentials like refrigerators, furnaces, sump pumps, and medical equipment. A licensed electrician can perform a professional load calculation. Many homeowners find systems in the 10kW to 14kW range suitable for powering essential circuits. Our guide to Champion 10,000-watt generators explores one common capacity.
Can I install a standby generator with an ATS myself?
No, installation must be handled by a qualified, licensed electrician. The process involves working with natural gas or propane lines and connecting directly to your home’s electrical panel. Improper installation can be extremely dangerous, violate codes, and void the manufacturer’s warranty. Always hire a professional for this critical task.
How often does a standby generator need maintenance?
Modern standby generators perform weekly self-diagnostic tests to ensure they are ready. Annual maintenance by a qualified technician is recommended. This typically includes an oil and filter change, spark plug inspection, battery check, and a general system verification. Following the manufacturer’s maintenance schedule is crucial for long-term reliability.
