Choosing Your Home Standby Generator
Power Output and Whole-House Coverage
Selecting the correct power capacity is your first critical decision. You must calculate the total wattage of the essential circuits you need to run simultaneously during an outage. This includes major appliances like refrigerators, HVAC systems, well pumps, and lighting.
Models like the Generac 28kW Whole Home Generator or the Kohler 26RCAL-200SELS Air-Cooled Standby Generator are engineered for extensive whole-house coverage. They can handle heavy loads, ensuring your home operates normally. For a broader perspective on backup solutions, explore our category page for Home Backup Generators.
Fuel Type and Automatic Transfer Switch
Most standby generators in this category connect to your existing natural gas or liquid propane (LP) supply. This provides a nearly endless fuel source, a significant advantage over portable units. The inclusion of an automatic transfer switch is non-negotiable for true standby operation.
This device constantly monitors utility power. The moment an outage is confirmed, it safely disconnects your home from the grid and commands the generator to start, all within seconds. Systems like the Kohler 20RESCL-200SELS 20 include this switch, ensuring a seamless and automatic transition to backup power.
Smart Features and Remote Monitoring
Modern generators offer sophisticated connectivity for peace of mind. Features like built-in cellular capability, as found on several Generac models, allow you to monitor status, receive maintenance alerts, and even start or stop tests from your smartphone via an app.
This remote access is invaluable when you are away from home, letting you verify your property remains protected. The Anker SOLIX E10 system represents a different, tech-forward approach with its modular, battery-based design and rapid switchover, appealing to those interested in solar compatibility.
Durability, Warranty, and Professional Installation
These are permanent outdoor appliances. Look for corrosion-resistant, weatherproof enclosures rated for your climate. A comprehensive warranty reflects the manufacturer’s confidence in their product. All Generac models come with a strong five-year limited warranty and support.
Professional installation by a certified electrician is mandatory for safety, compliance with local codes, and proper integration with your home’s electrical panel and fuel line. This ensures optimal performance and preserves your warranty. Learn more about different applications on our parent page, Generators by Use Case.

Frequently Asked Questions
How quickly does a standby generator turn on after a power outage?
True standby generators activate automatically. They typically sense the outage and transfer power to your home within 10 to 30 seconds. This rapid response keeps essential appliances running and prevents data loss or household disruption.
Can a standby generator power my entire house?
Yes, the models reviewed here are designed for whole-house coverage. The key is selecting a unit with sufficient wattage (kW output) for your home’s total electrical load. A professional installer can perform a load calculation to confirm the correct size for your specific needs in 2026.
What is the main difference between a Generac model with and without an included transfer switch?
The primary difference is convenience and potential cost. A bundle that includes the transfer switch, like the Generac 28kW Whole Home Generator with Transfer Switch, means you purchase all major components together. If the switch is not included, you must source it separately, which requires ensuring compatibility.
How often does a standby generator require maintenance?
Like a car, standby generators need periodic maintenance for reliable operation. This typically includes oil and filter changes, spark plug replacement, and battery checks. Most systems have an exercise mode that runs automatically weekly to keep components lubricated and ready. Always follow the manufacturer’s maintenance schedule outlined in the manual.
