Generac 18 kW Home Standby Generator 200A Transfer Switch
The Generac 18 kW Home Standby Generator is a dual-fuel backup power system that runs on either liquid propane or natural gas and connects to an existing fuel supply. It monitors utility power and starts automatically within seconds of an outage, then transfers the home's electrical load back to the utility and shuts down once service returns.
Included with the unit is a 200-amp automatic transfer switch, and the Power Zone 200 controller offers an LCD interface, system diagnostics, a multilingual display, and Wi-Fi and Bluetooth connectivity for remote monitoring. True Power Technology delivers power with less than 5% total harmonic distortion, while the weather-resistant aluminum enclosure and Quiet-Test Mode support dependable, low-noise outdoor operation.
