If you’re at all on the fence about whether or not you need a standby generator, consider its benefits. Here are some of the most important pros to owning a whole-house generator.
- Standby generators connect to the home with an automatic transfer switch that instantly kicks the generator on when the power goes out.
- They are sized to the home, meaning they can usually handle all of the home’s needs during a power outage, not just the refrigerator and a few outlets.
- Since they are connected to a home’s integrated natural gas or liquid propane supply, standby generators can run for days or longer without needing to refuel.
- They can prevent serious damage caused by frozen pipes by allowing the user to keep the heat on in the home.
- They can save money by ensuring food in your refrigerator and freezer stays cold, eliminating food spoilage.
- They can help you stay safe during lengthy storms and their aftermath while also allowing you to charge devices, stay up-to-date on news, and even entertain yourself to pass the time.
Having lived through a few power outages myself, I can tell you there’s nothing like the peace of mind a whole-house generator brings. Beyond the obvious perks, like keeping your fridge running, these systems can be a lifesaver in extreme weather. For instance, during a brutal winter storm a few years back, my neighbor’s generator kept their heat on, preventing costly pipe repairs. Data from the U.S. Energy Information Administration shows that power outages affect millions of households annually, with some lasting days. A standby generator ensures you’re not left scrambling for candles or worrying about spoiled food. Plus, with the ability to power entertainment systems, you can keep the kids distracted with movies instead of complaints. Another practical tip: if you work from home, a generator can keep your internet and computers running, saving you from missed deadlines.
Assessing Your Backup Power Needs
To ensure the backup generator can keep up with all of the home’s needs, it’s important to size it properly. This can be a complicated process that involves collecting past energy bills, determining the maximum wattage that each device in the home will draw on start-up, and more math equations. Many generator companies have generator size calculators on their websites to help give customers a preliminary estimate. However, a professional should be consulted to help determine how large a residential generator should be. While it might seem like just opting for the largest standby generator available is the safest option, oversize generators can be loud and inefficient. However, choosing an undersized generator is usually not a smart investment. What’s the happy medium? The KOHLER 26 kW Home Generator. This generator produces up to 26 kilowatts of power while operating at just 56 to 67 decibels. That means it can power all major systems, appliances, and electronics within a large home at a noise level equivalent to an HVAC unit. It’s the gold standard of whole-house generators on the market.
Sizing a generator isn’t something you want to guess at. I learned this the hard way when a friend bought a cheap, undersized unit that couldn’t handle their AC during a summer blackout—talk about frustration! To get it right, you’ll want to tally up the wattage of everything you need to run. For example, a typical refrigerator might need 600-800 watts, but an air conditioner can demand 3,000 watts or more at startup. A pro tip: don’t forget to account for “surge” power—appliances like AC units or pumps pull extra juice when they kick on. According to the National Electrical Manufacturers Association, most homes need 20-30 kW for full coverage, which is why the KOHLER 26 kW model is such a sweet spot. If you’re unsure, many electricians offer free consultations to analyze your energy bills and recommend the right size. This step can save you from overspending on a noisy, gas-guzzling giant or skimping on a unit that leaves you in the dark.
Fuel Type Considerations
Whole-home generators have internal combustion engines at their core. They intake fuel, compress it, ignite it, and then exhaust it, forcing the cylinders to operate and generate power. The fuel they take in may vary, though. Natural gas generators can run off the home’s piped natural-gas supply, ensuring that there is always fuel available. Liquid propane generators can be tied to large propane storage tanks. Natural-gas and propane generators are both great choices. They’re quiet, clean, and efficient. And fortunately, the KOHLER 26 kW Home Generator offers homeowners the option of either.
Choosing between natural gas and propane can feel like picking between two good options, but it’s worth thinking through. I’ve seen folks lean toward natural gas because it’s piped directly to the home—no need to worry about refilling tanks. But if you live in a rural area without a gas line, propane’s the way to go. Propane also has a slight edge in colder climates since it burns cleaner and doesn’t gel like diesel might. According to the Propane Education & Research Council, propane generators can store enough fuel to run for weeks, which is a game-changer during extended outages. A practical tip: if you go with propane, make sure your tank is at least 250 gallons to avoid frequent refills. Also, consider maintenance—natural gas lines need less upkeep, but propane tanks require periodic inspections. Either way, the KOHLER 26 kW’s flexibility means you can choose what fits your home’s setup without sacrificing performance.
Permits and Approvals
Homeowners can’t just call an electrician and ask them to install a generator. There are certain permits and approvals that need to be taken care of before a whole-house generator can be connected to the home. Building codes can vary greatly between states, counties, and even cities, which is why it’s helpful that Kohler dealers pull all necessary permits and hire reliable contractors for the homeowner, eliminating this often confusing and stressful step in the process of installing a standby generator.
Navigating permits can be a headache, but it’s non-negotiable. When my cousin had a generator installed, they were surprised by how many hoops they had to jump through—electrical, plumbing, and even a zoning permit in their town. Building codes are strict because generators tie into your home’s critical systems, and a bad setup could be dangerous. For example, the International Code Council notes that improper installations can lead to electrical fires or gas leaks, which is why municipalities enforce permits. A good dealer, like those working with Kohler, will handle this for you, but it’s smart to double-check what’s required in your area. Some cities demand noise level compliance, especially if you’re near neighbors. A quick call to your local building department can clarify things and save you from costly fines or delays.
Electrical
Standby generators should be tied into the home by licensed, experienced electrical contractors only. To ensure this, your municipality may require an electrical permit. This permit ensures that the generator, its wiring, and the transfer switch are all installed correctly and safely. The building department will likely inspect the connections after their installation.
Electrical work for generators is no joke—it’s not like swapping out a light switch. The automatic transfer switch, which flips your home to generator power during an outage, is the heart of the system. If it’s not wired right, you could end up with power surges that fry your appliances. I saw this happen to a friend who hired a sketchy contractor to save a few bucks—ended up costing them thousands in repairs. The National Fire Protection Association reports that faulty electrical work is a leading cause of home fires, so sticking with a licensed electrician is a must. A pro tip: ask your contractor to walk you through the transfer switch setup so you understand how it works. Also, make sure they test the system after installation to confirm it kicks on smoothly when the power goes out.
Plumbing
Before natural gas or propane can be piped out to the generator’s location, you may need to obtain a plumbing permit. The permit serves as permission but also somewhat verifies that the contractor knows what they’re doing when it comes to pipe fitting. The building department will probably check all of the fittings and pressure test the pipe to ensure everything is operating properly and safely.
Plumbing for a generator isn’t just about hooking up a pipe—it’s about safety. A leaky gas line is a disaster waiting to happen, which is why permits and inspections are so critical. When I visited a friend during their generator install, the plumber spent hours pressure-testing the lines to ensure no leaks. According to the U.S. Department of Energy, improperly installed gas lines can lead to carbon monoxide risks, so don’t skimp on this step. If you’re using propane, make sure the tank’s placement complies with local codes—some areas require it to be a certain distance from your home. A practical tip: have your plumber check for corrosion-resistant piping to extend the life of your setup, especially if you live in a humid or coastal area.
HOA
Homeowners who live in residential communities might have to get approval for their generator from their HOA, or homeowners association. The HOA may have regulations about how large a generator can be, how loud it can be, and even what it looks like.
HOAs can be a real stickler when it comes to generators. I know someone who had to repaint their unit to match their home’s exterior because the HOA deemed the original color “too industrial.” Some HOAs cap noise levels at 60 decibels, which is another reason the KOHLER 26 kW’s quiet operation is a big win. Before you buy, check your HOA’s bylaws—many require a detailed plan showing the generator’s size, placement, and even landscaping to hide it. A tip: bring your HOA board photos of the generator and its specs early on to avoid surprises. If you’re in a tight-knit community, it might also help to chat with neighbors to get their buy-in before the approval meeting.
Why You Shouldn’t DIY This Project
DIYers shouldn’t hook up a generator to a house; whole-home generators need to be installed by licensed contractors. These devices create a lot of power and have to tie into the home’s fuel source and electrical panel to be operational. It’s a potentially dangerous project that takes trained professionals. When installing the KOHLER 26 kW Home Generator, the dealer will hire a plumber to safely connect the natural gas or liquid propane to the generator. But there’s more than a fuel line at play, there’s also an automatic transfer switch. Only a licensed electrician should install the automatic transfer switch, as it’s critical that the steps are performed correctly.
I’m all for DIY projects, but this isn’t one to mess with. A buddy of mine thought he could save money by wiring his own generator—ended up with a shorted-out panel and a hefty electrician bill to fix it. Whole-house generators involve high-voltage wiring and gas lines, which can be deadly if mishandled. The Consumer Product Safety Commission warns that improper generator setups can cause electrocution or carbon monoxide poisoning. Hiring pros isn’t just about following codes; it’s about keeping your family safe. A practical tip: when choosing a contractor, ask for references from past generator installs and verify their licenses. It’s worth the extra time to ensure the job’s done right.
Timing the Installation
Regardless of where you live, the best time to buy a home generator and have it installed is before you need it. You definitely don’t want to wait until the eve of a major storm because, typically, dealers aren’t able to pull permits and coordinate contractors on such short notice.
Timing is everything with generator installation. I remember a neighbor scrambling to get a unit installed during hurricane season—dealers were booked solid, and they were stuck without power for days. The Federal Emergency Management Agency notes that demand for generators spikes during storm seasons, often leading to delays. Plan ahead, ideally in the off-season like spring or early fall, when contractors aren’t swamped. A pro tip: once your generator’s installed, test it monthly to ensure it’s ready when you need it. Also, consider scheduling maintenance checks with your dealer to keep it in top shape, especially if you live in an area prone to outages.
Site Selection
Another point to consider is where the generator will sit. It should be relatively close to the gas and electrical meters, as this makes tying the generator into the home’s utilities easier. However, it must also be at least 5 feet away from windows, doors, and even soffit vents. Also, generators need a stable base. In many cases, the best option is to install the generator on a concrete slab specifically for the generator. The dealer will help you choose the right location for your generator, and coordinate installation.
Choosing the right spot for your generator is trickier than it sounds. I helped a friend pick a location, and we had to balance keeping it close to the gas meter while avoiding their kids’ play area. The 5-foot rule isn’t just a suggestion—it’s to prevent exhaust fumes from entering your home, which can be a carbon monoxide risk. According to the Occupational Safety and Health Administration, generators should also be placed in well-ventilated areas to avoid heat buildup. A concrete slab is ideal because it keeps the unit stable and prevents sinking in soft soil. A practical tip: if your yard is prone to flooding, elevate the slab slightly to protect the generator. Your dealer can also suggest landscaping tricks, like low shrubs, to make the unit blend into your yard.
