Best power quality in class — THD below 3%, quietest enclosures, the healthcare and mission-critical default
10–4000 kW111 modelsdiesel, natural-gas, lpg
Why buyers choose Kohler
Best power quality — total harmonic distortion below 3% (industry typical is 5-8%), critical for sensitive electronics
Quietest enclosures — industry-leading noise attenuation across the standby lineup
Healthcare default — specified by more hospital systems than any other brand for NFPA 110 compliance
Decision-Maker 6000 controller — advanced paralleling and load management built in
34% better 10-year TCO than sticker price suggests when factoring maintenance and reliability
Who Kohler is for
Hospitals, data centers, noise-sensitive commercial sites, facilities with sensitive electronics, and buyers who prioritize power quality and total cost of ownership over purchase price.
What to consider before specifying Kohler
*10-15% price premium over comparable Generac units
*Rehlko rebrand (Platinum Equity acquisition, Sept 2024) causing buyer confusion and parts catalog transition
*Mobile monitoring capabilities lag behind Generac Mobile Link
Kohler generators are the power quality benchmark in the standby generator market. With total harmonic distortion consistently below 3% — against an industry norm of 5-8% — Kohler is the default specification for hospitals, surgical centers, and data centers where clean power is not optional. The company's enclosures are also the quietest in the industry at comparable power ratings, which matters for installations near occupied spaces, residential property lines, or noise-sensitive commercial tenants.
The honest limitation is cost and ecosystem lock-in. Kohler units price similarly to Caterpillar and above Cummins and Generac by 10-15%. The Decision-Maker 6000 controller, while powerful, is proprietary — replacement modules, programming, and integration work must go through Kohler-certified channels. Buyers who prefer open-architecture controls (like the Basler DGC-2020 found in Blue Star units) should weigh that dependency carefully. Kohler's dealer network, while strong, is also smaller than CAT's roughly 200 US locations or Generac's 10,000-plus installer base.
The September 2024 acquisition by Platinum Equity and subsequent rebrand to Rehlko has created some market uncertainty, but the engineering and manufacturing operations are unchanged. Generators branded Kohler and those emerging under the Rehlko name are mechanically identical products from the same facilities with the same warranty backing. For specifiers, the rebrand is a corporate event, not a technical one — the sub-3% THD and quiet enclosures that earned Kohler its healthcare-default status remain intact.
Frequently asked questions
What is THD and why does Kohler's sub-3% rating matter?
Total harmonic distortion (THD) measures how much the generator's output deviates from a pure sine wave. Kohler's alternators consistently produce THD below 3%, while most competitors fall in the 5-8% range. Lower THD means cleaner power for MRI machines, UPS systems, and precision electronics — equipment that can malfunction or sustain damage from distorted waveforms.
What is the Rehlko rebrand?
In September 2024, Platinum Equity acquired Kohler's power division and announced a rebrand to Rehlko. The product engineering, manufacturing, and dealer network remain unchanged. Generators sold under the Kohler name and those sold under Rehlko are mechanically identical — the rebrand is corporate, not technical.
What is the Decision-Maker 6000 controller?
The Decision-Maker 6000 is Kohler's proprietary generator controller, offering automatic transfer switching, paralleling, and remote monitoring in a single integrated platform. It simplifies multi-unit installations but locks facilities into the Kohler ecosystem for replacement parts and programming — a consideration for buyers who prefer open-architecture controls.
