The Champion Power Equipment 12.5-kW Home Standby Generator with an Automatic Transfer Switch is The Simple Solution™ to a power outage. Enjoy peace of mind while ensuring security and convenience for your family during an emergency.
The generator starts automatically when the power goes out and returns to standby when power is restored. The 24-volt starting system operates in temperatures ranging from -22 F to 104 F with no warming kit necessary.
You’ll have the starting power you need during an emergency since the onboard battery charger maintains the charge at all times, plus, since the generator is connected to your propane or natural gas system, it never needs refueling. This unit also performs weekly self-diagnostic tests.
An all-weather, composite mounting pad is included for easy installation, plus the steel enclosure protects your generator from the elements.
There are two types of switches available that operate with this generator. The 100A automatic transfer switch is installed as a sub-panel with a fixed number of branch circuits connected. It is ideal for homeowners who want to power emergency essentials during a power outage as opposed to the whole house. It is housed in a NEMA 1 rated enclosure for indoor or NEMA 3R for outdoor use.
Or use our Whole House with Demand Control intelligent load management technology, your home’s power requirements are monitored continuously. This ATS can back up your home’s entire 200 Amp distribution panel with the ability to manage up to 8 high demand appliances for your Whole House power needs. Your home’s circuits are divided into prioritized zones – from vital to managed. If your generator nears maximum capacity, pre-designated, high demand appliances are managed to avoid overload. As soon as demand lowers, the generator will automatically reacquire the appliances that are managed. Appliances are managed and reacquired sequentially. The managed loads are grouped in two switched blocks of up to four loads each.
Our innovative gull-wing design provides easy access to the engine and control panel and allows a full view of the onboard control system.
The Champion OHV engine provides continuous power on propane or natural gas. The generator is shipped from the factory ready to run on natural gas. To convert to propane fuel an orifice in the Master Mixer Assembly (carburetor system) must be changed.
The sound-dampening lining and low-tone muffler reduce noise through a unique baffle system and make this unit the quietest in its class. The noise level is residential-friendly.
The alternator produces less than 5% total harmonic distortion (THD) to ensure safe use with even the most sensitive electronics.
This generator is available for all 50 states, and the automatic transfer switch is UL and cUL listed in the US and Canada. Buy with confidence - Champion Support and our nationwide network of service centers will back your purchase up with a 10-year/2,000 hour limited warranty and FREE lifetime technical support.

* Champion recommends using their dealers to perform maintenance and repairs but that is not always required. It is a case by case situation. If it is an easy repair and the customer is mechanically inclined Champion can send him the part and talk him through the repair without harming his warranty. Champion is pretty easy to work with in regards to warranty cases.
