Buying Guide: Key Purchase Considerations and Comparisons
Fuel availability and efficiency are critical for propane standby systems. Evaluate propane versus natural gas availability in your area, expected fuel costs, and the ease of refueling during extended outages. Look for manufacturers that offer under-5% harmonic distortion to protect sensitive electronics, such as refrigerators, computers, and home automation systems.
Consider generator size in relation to your home’s peak load. A unit rated around 20–26 kW is suitable for many larger homes with essential circuits and HVAC, while smaller homes may manage on 14–22 kW. Pay attention to self-test features (Quiet-Test) that minimize noise and fuel use without sacrificing readiness.
Remote monitoring is increasingly valuable for peace of mind. Generac’s Mobile Link and similar connectivity options let you track status, maintenance alerts, and performance from anywhere. Ensure the model includes a robust warranty (ideally 5 years) to protect against long-term failures and address installation concerns.
Installation considerations include transfer switch compatibility, installation complexity, and local permitting. Models with Power Line Carrier or simpler wiring options reduce installation time and cost. When choosing a propane-capable standby system, confirm that the unit will support both propane and natural gas if your fuel source may change over time.
Performance and noise are practical factors for residential use. Look for quiet-test modes, mufflers, and engine design that minimize noise during operation and self-testing. A reliable, well-maintained engine reduces maintenance downtime and helps ensure consistent backup power when needed most.
