Power outages can disrupt daily life, damage appliances, and even pose safety risks. A standby generator is a reliable solution to keep your home running during emergencies. Unlike portable generators, standby units automatically turn on when the power goes out, providing seamless backup electricity.
In this guide, we’ll explore the best standby generators for homes, key features to consider, and essential electrical knowledge to help you make an informed decision.
How Standby Generators Work
Standby generators are permanently installed outside your home and connected to your electrical system. They run on natural gas, propane, or diesel and activate within seconds of a power outage. Here’s how they work:
Automatic Transfer Switch (ATS) : Detects a power loss and signals the generator to start.
Engine Ignition : The generator’s engine powers up, producing electricity.
Power Distribution : Electricity flows through the ATS to your home’s circuits.
Automatic Shutoff : When utility power returns, the generator shuts down and resets.
This process ensures uninterrupted power without manual intervention.
Key Factors to Consider When Choosing a Standby Generator
Power Output (Wattage)
Generators are rated in watts (W) or kilowatts (kW). To determine the right size:
- Calculate your home’s essential load (fridge, lights, HVAC, sump pump, etc.).
- Add a 20-30% buffer for startup surges (motors need extra power at startup).
Fuel Type
Natural Gas : Convenient if you have a gas line; runs continuously.
Propane : Stored in tanks; good for areas without natural gas.
Diesel : More efficient but requires regular maintenance.
Noise Levels
Standby generators operate between 60-70 decibels (similar to a dishwasher). Look for models with sound-dampening enclosures.
Transfer Switch Type
Automatic Transfer Switch (ATS) : Best for seamless power transition.
Manual Transfer Switch : Requires user intervention; less expensive.
Brand Reputation & Warranty
Top brands like Generac, Kohler, and Cummins offer reliable models with 5-10 year warranties.
