Buying Guide: Key Purchase Considerations
- Power needs: Assess your home’s essential circuits and HVAC load to determine required kilowatts. Smaller homes can often run on 10–14kW, while larger houses may need 22–24kW.
- Transfer switch compatibility: Ensure the unit matches your service panel and transfer switch configuration (e.g., 100, 150, or 200 amp).
- Fuel type and availability: Most home standby units use natural gas or propane. Confirm fuel supply is reliable for your location and fuel prices.
- Remote monitoring: Built-in cellular connectivity with a Mobile Link or equivalent app helps track performance and schedule maintenance remotely.
- Installation footprint: Larger kilowatts require more installation space and a concrete pad. Check local codes and clearance requirements.
- Maintenance and warranties: Review service intervals, parts availability, and subscription needs for remote monitoring features.
- Noise and vibration: Consider decibel levels and mounting options if the generator will be near living areas or bedrooms.
Frequently Asked Questions
- What size standby generator do I need for a small home?
A 10–14kW unit typically covers essential loads for small homes, including refrigeration and lighting, with automatic transfer during outages. - Do these generators require a cellular monitoring plan?
Many models include built-in cellular connectivity, but some features may require a premium subscription for full monitoring and alerts. - Can I install a standby generator myself?
Standby generators involve electrical and fuel connections and require professional installation to meet safety codes and warranty terms. - Will a 200-amp transfer switch work with a 22kW or 24kW unit?
Yes, with the appropriate transfer switch and electrical design, but verify panel compatibility and local code requirements. - What maintenance is needed for standby generators?
Routine services typically include oil changes, filter replacements, and battery checks; remote alerts help schedule preventive maintenance. - Is a quieter model better for an urban setting?
Quieter models reduce ambient noise, which is beneficial near bedrooms or neighbors, though they may trade some peak output for noise performance.
