The KOHLER RCA 20,000-Watt Dual Fuel Home Standby Generator is engineered to provide dependable backup power for homes with substantial electrical demand. Capable of operating on either liquid propane or natural gas, this generator offers fuel flexibility and consistent standby performance during utility outages.
Model 20RCA-QS6 is part of Kohler’s Quiet-Series lineup, incorporating acoustic-reducing design elements to minimize operating sound levels compared with standard standby generators. When paired with an appropriately sized automatic transfer switch (sold separately unless bundled), the system detects utility power loss, starts the generator, and transfers load automatically — returning to utility service once power is restored.
This unit supports HVAC equipment, appliances, lighting, and other critical household systems, making it a strong choice for residential whole-home backup power where fuel flexibility and reduced noise are priorities.
