ATS usage with portable generators

No, Generac Automatic Transfer Switches are designed to be used with a Generac-manufactured home standby generator. On a home standby system, utility sensing is done in the generator's controller, and portable units do not have controllers. For more information about how an automatic transfer switch is used to transfer power, see the How Does an Automatic Transfer Switch Work? article.

Some compatible portable generators will work with a manual transfer switch: What is the HomeLink manual transfer switch?

Generac does not recommend attempting to connect a manually-started portable unit with an automatic transfer switch. This connection may result in damage to both the transfer switch and the generator, which could potentially affect both units' warranties.
