Buying Guide: Key Purchase Considerations
Power needs and load management: Assess your essential circuits and total wattage to determine whether you need a unit in the 10 kW range or a larger 13 kW range. Consider future expansions like additional circuits or new appliances.
Fuel options and availability: Gasoline-powered systems are common, but dual-fuel or tri-fuel units offer flexibility when one fuel source is scarce. Propane and natural gas may affect running costs and emission levels.
Transfer switch compatibility: For seamless whole-house backup, pair a generator with a compatible automatic transfer switch (ATS) that matches your service panel. Confirm the switch amperage (e.g., 100 Amp) and the number of circuits supported.
Safety features: Look for CO alarms, auto shutoff, and weather-resistant enclosures. CO shields and proper ventilation are essential for delivering safe, reliable power during outages.
Remote monitoring and maintenance: Wi-Fi or mobile-link capabilities let you monitor status and maintenance alerts remotely. This is valuable for long outages or vacation homes where you can’t check in physically.
Portability vs. permanent installation: Standby generators with concrete pad or permanent placement offer seamless operation during outages but require installation. Portable dual-fuel units offer flexibility but require manual setup and connection to transfer switches or power distribution systems.
Reliability and warranties: A solid warranty (such as 5-year terms) provides long-term protection for your investment. Check service support networks and expected maintenance schedules to minimize downtime.
Noise and emissions: Consider the noise level (dBA) and emission standards for your neighborhood or HOA. Engines with modern quiet technology typically deliver more acceptable noise profiles for residential areas.
