Generac 18 / 20 Kilowatt Guardian Series Standby Generator with 200-Amp, Service Entrance Rated, NEMA 3R Automatic Transfer Switch supplies your entire home during an outage.
The 70391 is a permanently connected standby generator with automatic transfer switch that operates your home’s existing natural gas (18kW) or LP Gas (20kW) supply. It monitors utility power 24/7, then starts and runs automatically upon detecting a power outage and continues to run until the utility restores power.
The RXSW200A3 Automatic Transfer Switch is NEMA 3R rated for indoor or outdoor use. It automatically isolates the main service panel from the electric utility and connects it to the generator to supply the entire home with utility grade power. ATS includes the Smart A/C Module to manage up to four prioritized air conditioner units without overloading the generator. Accepts Generac Smart Management Modules to prioritize and manage other high-voltage loads.
True Power Technology delivers best-in-class power quality (utility grade power) with less than 5 percent total harmonic distortion for electrical power that operates all your appliances and the most sensitive electronics. The generator regulates voltage to ± 1 percent while the controller maintains a constant 60 hertz frequency.
