Briggs & Stratton 40638 20kW Generator with Aluminum Enclosure & Dual 200A SE Transfer Switch Features:

In the event of a power failure, 20kW Briggs & Stratton 40638 whole house generator automatically begins to supply power to your two-5-ton air conditioners, security system, and other home appliances. It keeps the family, house, and workplace safe during a blackout. This dual fuel air-cooled gas generator requires no refueling. It will continue to supply clean power with a good sine wave till grid power supply resumes. Sensitive electronics have microcircuits that get damaged with voltage spikes. This 60Hz 120/240v single-phase model delivers outstanding digital voltage and frequency so you can use all your sensitive electronics with total peace of mind.

When you add additional load to the generator the Symphony® II Power Management System ensures it manages the load without dropping power to other appliances, which can damage the product. During emergencies, the dual 200-amp automatic transfer switch offers the comfort and convenience of generator power without the call for manual operation. This whole house generator can be used at home or work as a backup source of power. It gives total coverage to large-sized houses and small businesses. With less than 5% total harmonic distortion it is perfect for use with modern computers, laptops, cell phones, and tablets that we use daily.
