The Briggs & Stratton 040753 bundle includes the PowerProtect 18kW PP18 generator, 200 Amp automatic transfer switch, and Symphony Choice Power Management. The 18kW PP18 emergency generator keeps you, your family and your business safe during a power outage. It generates ample power to run two five-ton air conditioners, computers, refrigerators, ovens and all other home appliances. Storms and other events may disrupt the power grid for several hours and even sometimes for days. This 18kW model is easy to use and maintain and is perfect for small or medium-sized homes. It needs no refueling and will continue to keep the family safe and the day running until the grid power supply is restored. Connect it to the kitchen gas line for an unlimited supply of fuel if the LP cylinder runs out. It is quieter, more cost-efficient, compact and powerful than other generators of its class. The Symphony® Choice Kit offers simplified prioritized whole-house power. It manages additional loads well, and you can specify your needs via cell phone. The automatic transfer switch lets you enjoy the comfort and convenience of generator power without the need for manual operation. Along with emergency use, this generator is certified for non-emergency use.
