Buying Guide
- Capacity and load requirements: Assess your home’s essential loads (HVAC, refrigeration, sump pump, lighting, and small electronics). Generators in the 14kW–26kW range often cover typical mid- to large-sized homes, but exact sizing matters for seamless operation during outages.
- Transfer switch size and compatibility: A 100 Amp or 200 Amp transfer switch determines how many circuits are automatically powered. Ensure compatibility with your electrical panel and outdoor installation space.
- Remote monitoring and connectivity: WiFi or cellular monitoring helps you stay informed when you’re away. Consider subscription requirements for full Mobile Link or similar services and any associated costs.
- Reliability and warranty: Look for models with solid warranties and reputable brands. A longer warranty can add peace of mind for long-term investments in home protection.
- Fuel type and availability: Natural gas and propane are common. Confirm fuel supply in your area and the installer’s recommendations for your home’s fuel setup.
- Noise and footprint: Consider the generator’s noise levels and required outdoor clearances. Some models feature quieter operation modes or more compact footprints for limited spaces.
- Installation considerations: Professional installation ensures proper venting, exhaust routing, and electrical integration. Verify local codes and permit requirements before purchase.
