Buying Guide: Key Purchase Considerations
- Power needs: Match generator size to your home’s total electrical load and essential circuits. For larger homes, consider 22kW or 26kW units; smaller homes may do well with 10kW–14kW models.
- Transfer switch capacity: A higher amp transfer switch (100 Amp, 200 Amp) allows more circuits to switch over automatically. Choose one that aligns with your panel and anticipated load.
- Fuel type and availability: Most home standby generators run on natural gas or propane. Confirm your fuel source and local gas supply capacity for your peak loads.
- Connectivity and monitoring: Cellular or Wi‑Fi monitoring helps track performance and maintenance. Some features may require a paid subscription for full benefits.
- Installation considerations: Outdoor placement, weather resistance (NEMA 3R or similar), ventilation, and proximity to living spaces influence choice. A professional install is recommended.
- Noise and vibration: Some models offer quieter operation and test modes. If noise is a concern, compare decibel ratings and test procedures.
- Warranty and long-term support: Look for reputable brands with strong service networks and multi-year warranties to ensure dependable operation during outages.
