Buying Guide: Key Considerations For Choosing A Whole House Generator
- Power needs: Calculate your essential circuits and total continuous load to determine kW requirements. Higher kW units cover more appliances and systems but come with higher upfront and installation costs.
- Fuel type and availability: Natural gas and propane offer different fuel reliability and costs. Dual-fuel options add flexibility but can introduce complexity.
- Transfer switch capacity: A larger transfer switch supports more circuits; ensure it aligns with your home’s electrical panel and expected loads.
- Remote monitoring and connectivity: Cellular or Wi-Fi monitoring helps with proactive maintenance. Subscriptions may be required for premium features.
- Installation considerations: Site preparation, permits, gas line or propane connections, and professional installation impact total costs and timelines.
- Warranty and service: Look for a solid warranty and local service availability to minimize long-term ownership costs.
- Future-proofing: If you anticipate expanding electrical loads (new HVAC, electric vehicle charging), choose a unit that can handle growth or match an upgrade plan.
