Are Generac portable generators internally or externally regulated?

Generac portable generators are externally regulated by utilizing either an automatic voltage regulator or a capacitor.

Internal vs. Externally Regulated Generators

An externally regulated generator is a generator where the voltage output is regulated by an external device, such as a voltage regulator or stabilizer. This device is connected to the generator through electrical wiring and monitors the voltage output to ensure it remains within a certain range. If the voltage output exceeds or falls below the preset range, the voltage regulator adjusts the voltage output accordingly.

An internally regulated generator is a generator where the voltage regulation is built into the generator itself. The voltage regulation is controlled by the generator's internal accessories and components, such as its voltage regulator or automatic voltage controller. Unlike an externally regulated generator, an internally regulated generator does not require an external voltage regulator or stabilizer to maintain a stable voltage output.
