Buying Guide
Power needs: Assess your home’s essential circuits and total running watts. A larger standby unit (10–22kW) suits whole-house protection, while portable tri-fuel or dual-fuel models fit smaller homes or higher mobility needs.
Fuel type and availability: Decide between natural gas, propane, or dual-fuel. Gas and propane have different peak outputs and fuel costs, while propane storage is independent of utility outages but requires more frequent refueling depending on usage.
Installation and integration: Standby generators require professional installation, transfer switches, and electrical permits. Ensure the transfer switch matches your panel size and that your outdoor enclosure is weather-rated for your climate.
Monitoring and remote management: Cellular or WiFi monitoring helps track performance and maintenance. Consider subscriptions or app accessibility when evaluating long-term use and peace of mind.
Portability vs. permanence: Portable units are flexible for RV use or short outages, but standby generators offer automatic startup and uninterrupted service for multi-room comfort and critical loads during extended outages.
FAQ
- What size standby generator do I need for a typical home? A 10–22 kW standby unit is common for mid- to large homes with several high-demand appliances. Size depends on essential circuits and climate.
- Can I install a standby generator myself? No. Standby systems require professional installation to ensure safety, proper wiring, and code compliance.
- Is dual-fuel performance as good as gasoline-only power? Dual-fuel options offer flexibility, but peak output can vary between fuel types. Check the manufacturer’s specifications for exact numbers.
- Do I need a transfer switch? Yes. A transfer switch automatically routes power from the generator to house circuits during outages and is essential for safe operation.
- Will a portable generator power my whole home? Typically not. Portable models are best for essential circuits or smaller living spaces; standby units are designed for whole-house coverage.
- What maintenance is required for standby generators? Regular oil changes, filter checks, and battery maintenance are common, along with periodic run tests to ensure readiness.
