Guardian standby units are assembled in Wisconsin
Generac's FAQ answers the question directly: "Our home standby generators are assembled Wisconsin, USA, using both foreign and domestic parts." The company was founded in 1959 and is headquartered in Waukesha, Wisconsin. It says it built a new facility in South Carolina to meet standby demand, and local business press reports it also acquired a facility in Belvidere, Illinois.
That covers the Guardian 10kW, 18kW and 22kW units, sold with WiFi monitoring or with a 100 or 200 amp transfer switch.
Portables depend on the engine
Generac's portable FAQ says it designs and manufactures its G-FORCE and OHVI engines at its Wisconsin facilities, and that "Generac OHV engines are not engineered or manufactured in the U.S." The iQ3500 inverter lists a Generac OHV engine.
The GP2500i and iQ3500 inverters and the HomeLink 30 amp manual transfer switch kit carry no stated origin. For a US-assembled Generac, the Guardian standby line is the clear choice. For a portable, check the engine type and the label.
