Buying Guide: Key Purchase Considerations And Comparisons
- Power needs and headroom: For full-home backup, a 22kW to 24kW generator with a 200 Amp transfer switch is common. Assess essential loads (HVAC, water heater, ovens, sump pumps) and add a safety margin for startup surges.
- Transfer switch type: Automatic transfer switches (ATS) provide seamless, hands-off switching during outages, while manual switches are cost-effective but require operator intervention. Outdoor-rated enclosures with aluminum housings improve durability in harsh weather.
- Fuel type compatibility: Generators often support natural gas or propane. Ensure your home’s fuel supply meets the generator’s requirements and consider dual-fuel configurations if available.
- Remote monitoring and maintenance: WiFi-enabled models offer real-time status, alerts, and maintenance reminders. This can reduce downtime by enabling proactive servicing.
- Noise and efficiency: Look for models with quieter self-test modes and efficient fuel consumption. Self-diagnostic features help with quick troubleshooting.
- Warranty and service: A standard 5-Year Limited Warranty is common for standby systems. Verify what is covered (generator vs. transfer switch) and ensure local service support.
- Installation considerations: Outdoor installations require weatherproof enclosures, proper clearances, and potentially a licensed electrician for code-compliant wiring and gas connections.
- Cost and total value: While a higher-wower system or a WiFi-enabled model may carry a higher upfront cost, consider long-term energy reliability, potential insurance considerations, and resale value.
