Buying Guide: Standby Generators For Homes
What size generator do I need?
Estimate your essential loads first—refrigeration, heating or cooling, lights, and sump pumps. Add up the wattage and choose a unit that can handle these peak loads with some margin for surges. Larger homes or electric-heated spaces may require 16-26kW models or higher.
What is a transfer switch, and why does it matter?
A transfer switch safely connects the generator to your home’s electrical system and prevents backfeeding. Automatic transfer switches turn on the generator within seconds of a power outage. Choose a switch that matches your service panel capacity (100 Amp, 200 Amp, etc.) and circuit count to cover essential or whole-house loads.
How important is remote monitoring?
Remote monitoring helps you stay informed about generator status, fuel levels, and maintenance needs. Models with cellular or Wi-Fi connectivity can send alerts to your phone, but premium subscriptions may be required for full control and diagnostics.
Fuel type and efficiency
Most standby gens run on natural gas or propane. Electronic fuel and ignition controls improve efficiency and reduce emissions. Consider your fuel availability and family energy patterns when selecting a model for long outages.
Noise and footprint considerations
Look for generators with low decibel ratings and quiet-test features if your home is near neighbors or in a quiet neighborhood. Check the unit’s footprint and ensure proper outdoor clearance and venting as required by local codes.
Warranty and service expectations
Verify what the warranty covers and for how long. Regular maintenance is essential for reliability; confirm service options, technician availability, and recommended service intervals in your area.
Safety and installation tips
- Have a licensed electrician plan and install the transfer switch and wiring.
- Ensure proper ventilation, clearances, and weatherproof mounting.
- Register the system with your utility if required by your region.
Frequently Asked Questions
