When the grid fails, there’s no time for guesswork. Your power system either steps up or it doesn’t. And if you’ve ever lost electricity during a storm, you already know the difference between a generator that runs on reputation versus one that actually runs.
That’s why at Hatton Power & Propulsion, we recommend brands that don’t just promise reliability—they prove it. KOHLER standby generators and ONAN backup power systems have long been trusted by hospitals, military installations, and homeowners who demand more than just backup—they want assurance.
Let’s take a closer look at what makes these two brands the industry benchmark when it comes to dependable standby power.
Why Reliability Starts with the Right Brand
There’s a reason you hear the names KOHLER and ONAN more than others when talking about dependable power solutions. These aren’t off-the-shelf generators built to impress on paper—they’re engineered for real-world chaos. From high winds to ice storms, brownouts to complete blackouts, both KOHLER and ONAN are built to respond instantly, run steadily, and last for years under pressure.
When you’re powering a medical clinic, an RV miles from anywhere, or your own home while the streetlights are dark, KOHLER standby generators and ONAN backup power units aren’t just a luxury. They’re peace of mind in engine form.
Inside KOHLER Standby Generators: Engineered to Perform
If you’ve spent any time researching generators, you’ve likely seen KOHLER’s name pop up again and again. And that’s not by accident. These systems are designed to go toe-to-toe with commercial-grade demands, even in a residential setting.
One of KOHLER’s standout features is its PowerBoost™ technology. Translation? It handles large starting loads like central air conditioners without blinking. That means you won’t have to strategically power down appliances or worry about circuit overload.
And while most generators promise a “quick response,” KOHLER systems consistently deliver one of the fastest start-up times in the industry. Within seconds of detecting a utility outage, it’s generating power with little to no disruption.
The design itself is a thing of beauty. KOHLER enclosures are built from corrosion-resistant materials and designed to withstand brutal weather conditions. Pair that with their intuitive remote monitoring capabilities, and you’ve got a generator that doesn’t just perform; it communicates, self-checks, and stays ready without constant babysitting.
Whether it’s a brutal Nor’easter or a surprise summer storm, KOHLER standby generators are the kind of quiet guardians that never miss a shift.
The Rugged Muscle Behind ONAN Backup Power
Here’s where things get gritty. ONAN backup power is the Cummins brand you’ve seen parked behind mobile medical units, humming under RVs, and supporting off-grid operations that can’t afford to miss a beat.
Known for their engine durability and voltage consistency, ONAN units are built from the same DNA that powers long-haul trucks and military vehicles. These machines are made to keep running when lesser models would tap out. Think extreme temperatures, bumpy terrain, extended runtime; ONAN was practically born for it.
One of their more underrated strengths? Quiet operation. Their sound-attenuated enclosures help keep the volume down without sacrificing performance, making them ideal for residential installs, RV parks, or businesses where low noise matters.
But it’s not all about muscle. ONAN generators come loaded with smart diagnostics and onboard monitoring, so they’re as user-friendly as they are tough. Whether you’re remote camping or riding out a storm at home, ONAN backup power gives you confidence that lasts long after the utility crews have packed up for the night.
KOHLER vs. ONAN: Different Strengths, Same Standard
Now, you might be wondering, if both KOHLER and ONAN are so great, which one should I pick?
It depends. If you want a high-performance, integrated system with sleek monitoring, fast startup, and low-maintenance needs, KOHLER standby generators are a natural choice. They’re often the go-to for homes, small businesses, and anyone looking for a seamless, set-it-and-forget-it solution.
On the flip side, if you need serious ruggedness, field-tested engineering, and a unit that can take a beating without missing a beat, ONAN backup power systems check all the boxes. Especially in mobile setups or extreme environments, ONAN feels like overkill in the best possible way.
Either way, you’re not picking a gamble; you’re picking a guarantee.
