Safety note: Fuel-burning generators produce carbon monoxide (CO), an odorless, colorless gas that the U.S. Consumer Product Safety Commission (CPSC) warns can kill in minutes. Never run a generator indoors or in a garage, basement, crawl space, or shed, even with doors or windows open. Operate it outdoors, far from doors, windows, and vents, and install battery-operated CO alarms in your home. To power household circuits, use a transfer switch installed by a licensed electrician instead of back-feeding through an outlet.

Buying Guide: What to Look For in a Standby Generator
Power Output and Wattage
The first thing to consider is how much power you need. Standby generators range from 18kW to 26kW, and the right size depends on your home’s square footage and the appliances you want to keep running. A 22kW model can typically handle a medium-sized home with central air conditioning, while a 26kW unit is better for larger homes with multiple high-demand systems.
Think about what’s essential during an outage: lights, refrigerator, sump pump, and maybe a well pump. If you have electric heating or a large AC unit, you’ll need more wattage. Our list includes options from 18kW to 26kW, so you can match the power to your needs without overspending.
Fuel Type: Natural Gas or Propane
Most standby generators run on natural gas or liquid propane. Natural gas is convenient because it’s piped directly to your home, so you never have to worry about refueling. Propane, on the other hand, is stored in tanks and can be more portable if you move. Both options are reliable, but your choice may depend on what’s available in your area.
Many models, like the Generac Guardian series, come with dual-fuel capability, allowing you to switch between natural gas and propane. This flexibility is a huge plus, especially if fuel availability varies. For more on maintaining your property, check out our zero-turn mower buying guide for tips on keeping your outdoor equipment in top shape.
Transfer Switch and Installation
A transfer switch is essential for safely connecting your generator to your home’s electrical system. It automatically detects an outage and switches your circuits to generator power, then switches back when utility power returns. Look for models that include a 200-amp transfer switch, which is standard for whole-home coverage.
Installation should always be done by a licensed electrician, but the generator’s design can affect the complexity. Some units come with pre-wired transfer switches, making the process smoother. If you’re handy, you might consider a DIY approach, but professional installation ensures safety and compliance with local codes.
Monitoring and Smart Features
Modern standby generators often include WiFi or cellular monitoring, letting you check the system’s status from your smartphone. You can receive alerts about outages, maintenance reminders, and even start the generator remotely if needed. These features add convenience, but they also increase the price, so weigh the benefits against your budget.
Some models, like the Generac Guardian with WiFi monitoring, allow you to track power usage and schedule exercise cycles. This keeps your generator ready when you need it. If you’re tech-savvy, these smart features are worth the extra investment. For more on choosing between different types of equipment, see our comparison of zero-turn mowers vs. robot mowers.
Final Thoughts
Choosing the best standby generator under $10,000 comes down to your home’s size, fuel availability, and desired features. For a robust 26kW option with a 200-amp transfer switch, the Kohler 26RCAL-200SELS Air-Cooled Standby Generator stands out for its reliability and power. If you prefer a Generac with WiFi monitoring and a slightly lower wattage, the Whole House Backup Power, Natural Gas Or Propane (22kW) offers excellent performance and value. Both are proven performers that will keep your home powered through any outage.
Frequently Asked Questions
What size standby generator do I need for a 2,000 square foot home?
For a 2,000 square foot home, a 20kW to 22kW generator is usually sufficient, especially if you have natural gas. It can power essential circuits like lighting, refrigerator, and a central AC unit. If you have electric heat or a well pump, consider a 24kW or 26kW model for extra capacity.
Can I install a standby generator myself?
While it’s possible to install a standby generator yourself, it’s not recommended unless you have electrical and plumbing experience. A professional installation ensures proper connection to your gas line and electrical panel, and it’s often required for warranty coverage. Always check local codes and hire a licensed electrician.
How long do standby generators last?
With regular maintenance, a standby generator can last 20 to 30 years. The engine is designed for occasional use, but it needs periodic oil changes, filter replacements, and battery checks. Running the generator monthly for a few minutes helps keep it in good condition.
Do standby generators run on natural gas or propane?
Most standby generators are dual-fuel, meaning they can run on either natural gas or propane. Natural gas is ideal for homes with a gas line, while propane offers flexibility for remote locations. Check the specifications of the model you’re interested in to confirm its fuel options.
