Buying Guide: How To Choose The Right Home Backup Generator
How much power do you really need?
Estimate your essential circuits and appliances. For most homes, 5,000–8,000 starting watts covers lighting, refrigeration, and a few outlets during outages. Larger homes may require 10,000–15,000 watts or more, especially for HVAC and electric water heating.
Fuel type and availability
Gasoline generators are common and easy to refuel. Propane offers cleaner burns and easier storage, while natural gas provides constant supply if connected to a fuel line. Tri-fuel or dual-fuel options add flexibility during prolonged outages.
Start method and automation
Remote or electric start adds convenience, especially in bad weather. Automatic transfer switches enable hands-off power delivery to the home during outages. Consider whether you want manual or automatic backup with remote monitoring options.
Runtime and fuel capacity
Long runtimes reduce refueling frequency. Larger fuel tanks increase runtime but also the unit’s footprint and weight. Check fuel efficiency ratings and tank size to match your outage expectations.
Portability vs. standby-style use
Portable generators offer flexibility for job sites or camping. Standby-style units are fixed in place, designed to power a larger load with automatic operation. Your space, noise tolerance, and garage or deck setup influence the choice.
Safety and regulatory considerations
Outlets with rubber covers, CO sensors, and automatic shutoffs improve safety. Proper ventilation and clearance from doors, windows, and structures are essential. Verify local permits or installation requirements for transfer switches and gas connections.
Frequently Asked Questions
- What is the difference between portable and standby generators? Portable generators move where needed and require manual startup and often manual transfer to the home. Standby generators are installed to power the home automatically during outages and typically use an automatic transfer switch.
- How many watts do I need for essential home power? It depends on loads; refrigerators and lights require less, while HVAC and water heaters require more. A typical essential-load calculation ranges from 5,000 to 10,000 watts for comfort during outages.
- Is dual-fuel worth it? Dual-fuel or tri-fuel options offer fuel flexibility, reducing downtime if one fuel source is unavailable, which is valuable in prolonged outages.
- Do these generators require professional installation? Some units and transfer switches require professional installation to ensure safety and proper operation, especially for whole-house setups.
- Can I run a generator indoors to power the house? No. Generators must be operated outdoors with proper venting and clearances to avoid carbon monoxide hazards.
- How long do Generac or Westinghouse standby units last? Longevity depends on maintenance, usage, and environment. Follow manufacturer maintenance schedules for optimal performance.
