Briggs and Stratton Generators 40628 Details and Specifications

Briggs and Stratton 12kW Standby Generator

Never worry about losing power to your home again with an Automatic Briggs and Stratton 12kW Standby Generator System. The 40628 home backup generator and 150-Amp automatic transfer switch starts automatically within seconds after an outage hits and supplies power to your entire home. Amplify Power Management controls power for large appliances including air conditioners, electric water heaters, well pumps, and much more.

The Briggs and Stratton 12kW 40628 Generator keeps your family and home safe and comfortable while it prevents the hazards of an outage. Refrigerators and freezers stay cold. Sump pumps keep the basement dry. Heating and Air Conditioning keep your home cool in the summer and warm in the winter.

12kW Standby Generator + 150-Amp ATS

A new, more efficient alternator on the 40628 delivers exceptional voltage control and more power for starting motors including 5-ton air conditioners. Tighter voltage control for less than 5% total harmonic distortion (THD) means cleaner power for sensitive electronics and heavy-duty motors.

The New Briggs and Stratton Amplify Power Management System changes the way standby generators and automatic transfer switches manage generator power. An Amplify Power Management Transfer Switch determines which high voltage (240-Volt) appliances receive power and which wait their turn. The Amplify Smart Phone App gives homeowners control over the power management system. Older systems were limited to eight priority settings fixed at installation. Amplify provides up to 32 priorities controlled by the smart phone app. Now the Homeowner can give the electric dryer priority over the water heater or make both appliances wait until after dinner is cooked on the electric range. The 150-Amp Amplify Transfer Switch included with the Briggs and Stratton 12kW Standby Generator isolates the home and generator from the utility and supplies power during an outage.

An air-cooled 627cc OHV twin cylinder Commercial Vanguard Engine powers the 12kW Standby Generator. The engine runs on natural gas (NG) or propane (LPG) as selected by the installer. Built with Dura Bore Cast Iron Cylinder Sleeves, Low Oil detection and shutdown, and a fully pressurized lubrication system.

The user programmable weekly test mode run operates at a lower RPM for less noise, reduced wear, and lower fuel consumption.
