The Champion Power Equipment 100835 Home Standby Generator System includes 14kW aXis HSB Generator and 100A aXis ATS Whole House Automatic Transfer Switch. This generator never needs refueling operating on your home’s Natural Gas or LP fuel supply, starts automatically when utility power goes out, and turns off automatically when utility power is restored. The Champion aXis platform is a programmable, upgradable home standby system. The digital aXis Controller™ is equipped to provide continuous protection for the HSB. Power Line Carrier technology allows the system to communicate using your home’s existing wiring so your generator can talk to the automatic transfer switch and other components without needing to run separate wires, saving you money and time. With aXis Wi-Fi Direct your installer can use a tablet or phone to program your generator meaning faster setup and lower cost. This automatic Whole House transfer switch backs up your home’s 100-amp distribution panel and has the ability to manage your high-demand appliances by using our aXis Load Management Modules model 100868 (sold separately). Choose from four priority levels for each appliance from “must haves” to “nice to haves.” Multiple devices can share the same priority allowing for an unlimited number of loads that can be managed. If your generator nears capacity, high-demand appliances are automatically turned off according to their priority level to avoid overload. Load Management Modules also use Power Line Carrier technology simplifying installation. Featuring a NEMA 3R Service Entry rated enclosure, this switch may be installed indoors or outdoors and is ETL listed to comply with UL standards for the US. Buy with confidence - Champion Support and our nationwide network of service centers will back your purchase up with FREE lifetime technical support, a 10-year limited warranty on the generator and a 2-year limited warranty on the ATS.
