Champion 201566 18kW fleX™ Home Standby Generator with 200 Amp Transfer Switch
The Champion 201566 18kW fleX™ Home Standby Generator with 200 Amp Service Entrance Transfer Switch is a complete residential backup power system engineered to provide automatic whole-home protection during utility outages. Combining Champion's high-capacity 18kW fleX™ standby generator with a 200-amp service entrance automatic transfer switch, this package delivers reliable backup power for larger homes while eliminating the need for manual operation or portable generators.
Producing 18kW on liquid propane and 16.2kW on natural gas, this system provides the power needed to operate multiple HVAC systems, refrigerators, freezers, lighting, well pumps, sump pumps, home offices, and many other essential household loads. The included 200A service entrance transfer switch continuously monitors utility power and automatically transfers your home's electrical system to generator power during an outage before safely returning to utility service once power has been restored.
What makes the Champion fleX™ platform unique is its intelligent and expandable design. The programmable fleX™ load management system allows homeowners to assign appliances to priority levels, helping maximize available generator capacity while preventing overloads. Champion's Power Line Carrier technology eliminates dedicated communication wiring between the generator and transfer switch by utilizing your home's existing electrical wiring, simplifying installation and reducing labor costs. The integrated Wi-Fi Direct capability allows installers to commission and configure the system directly from a smartphone or tablet.
Built for dependable operation in demanding conditions, the generator features a 999cc Champion V-Twin engine, a 24-volt electric starting system capable of starting in temperatures as low as -22°F, and a rugged all-aluminum weather-resistant enclosure. Advanced airflow engineering helps reduce operating temperatures for longer component life, while less than 5% total harmonic distortion (THD) delivers clean, stable electricity for today's sensitive electronics and smart home technology.
