Description
Generac 24 kW Guardian with 200 Amp Transfer Switch (72101) Overview
The Generac 72101 pairs a 24 kW Guardian air-cooled home standby generator with a 200 amp automatic transfer switch. It runs on natural gas or liquid propane and starts automatically within seconds of a power outage, then switches back when utility power returns.
The generator uses Generac’s G-Force engine, built specifically for generator use, and True Power technology for power quality with less than 5% total harmonic distortion. A weekly Quiet-Test self-test runs at reduced engine speed, the LCD controller tracks maintenance intervals, and Mobile Link Wi-Fi monitoring lets you check status from your phone. The all-aluminum enclosure has a RhinoCoat powder-coated finish for corrosion resistance.
