Brand guide
Kohler / Rehlko standby generators
Kohler's home-energy generator business is now branded Rehlko. The residential lineup includes air-cooled and liquid-cooled systems with published warranty and cold-weather accessory information.
What stands out
- Published 5-year / 2,000-hour standard warranty information is comparatively clear in our source set.
- Official cold-weather package pages identify exact accessory kits for specific kW models.
- Kohler Energy Management monitoring is integrated across current residential product families.
What to verify
- • Legacy Kohler naming and current Rehlko branding can both appear in manuals and search results.
- • Battery group sizes remain incomplete across several residential models in our current research.
- • Air-cooled and liquid-cooled maintenance schedules should not be merged into one generic interval.
