20kW Briggs & Stratton 40637 Features:

  • The all-new 20kW Briggs & Stratton 40637 has improved controls and automatic voltage regulation. It features a robust commercial-grade Vanguard® 993cc V-Twin engine with a maximum of 3600-RPM.
  • The free 200-amp automatic transfer switch can be installed both indoors and outdoors. It manages the power supply to all home circuits.
  • The 60Hz model is offered in a 120/240v single-phase configuration. Engine noise and vibration are reduced by the dynamically balanced crankshaft. The engine has OHV cylinders with cast iron sleeve and OHV valves with hardened seats.
  • Briggs & Stratton Synthetic Oil makes this generator low maintenance. It shields the engine from sludge buildup and deposits. Advanced debris management keeps the engine clean and cool so the generator can give optimal performance for long hours.

  • Symphony® II Power Management System is customizable to your needs. It balances the load between low wattage (can opener, DVD player) and high wattage items (air conditioners, electric ovens).
  • The 2-line backlit LCD can be used to check the oil level, battery status, runtime and so forth. InfoHub Wireless Monitoring System allows you to check real-time generator status updates from remote locations using smartphones, tablets, laptops, and PCs.

Within seconds it senses the outage and automatically begins to supply power to the two 5-ton air conditioners, major appliances, and electronics.

It produces ample power to run heating, cooling, electric ovens, sump pump, washers and dryers, computers, and more. The smart load management system manages the additional load efficiently.
