Buying Guide: Key Purchase Considerations
What size generator do I need? Determine required power by listing essential circuits and their running watts. Larger homes with HVAC and multiple appliances may need 20 kW or more, while smaller homes can manage with 10 kW to 16 kW units. Transfer switches—ranging from 100 to 200 Amp—determine how many circuits can be automatically powered.
What fuel option is best? Standby generators typically run on natural gas or propane, offering continuous fuel supply for longer outages. Portable units may use gasoline or propane and are better suited for smaller outages or temporary power needs. Consider fuel availability and storage costs in your area.
What about monitoring and maintenance? Built-in cellular connectivity and Mobile Link provide real-time alerts and status updates, aiding proactive maintenance. Some models require a premium subscription for full features, so factor ongoing costs into the total ownership view.
Is installation included or required? Standby generators require professional installation, venting, and a transfer switch. Budget for installation, permit fees, and potential site prep. Portable backups may be easier to install but require manual setup and fuel handling during outages.
Warranty and service considerations? Look for multi-year warranties with clear terms for parts and labor. Local service availability can influence long-term maintenance costs and downtime.
