Generac generators are among the most sought-after in the residential market for their innovative, durable engine technology. They provide stable power for extended periods without maintenance concerns. The PowerPact® and Guardian® models are air-cooled whereas the Protector® QS series models have liquid-cooled engines. All Guardian® and Protector® QS models come with a 5 year limited warranty (base). The PowerPact® model comes with a standard 3 year warranty.
The table below shows each model’s power output and environmental factors of operation. Other specifications are available here.

For demanding commercial applications, Generac offers its liquid-cooled Protector® and Protector® QS series. The QS models feature the same powerful engine as the standard Protector® series but include noise-reducing enclosures, making them ideal for quieter operation in populated areas. These generators deliver utility-grade, stable power for long periods with minimal maintenance. For lighter commercial needs, larger models from the Guardian® series are a reliable choice. All Guardian® and Protector® models include a 5-year limited base warranty.
The table below shows the power output and environmental factors of operation for one model of many in each series. For information on all models, see the specifications available here.
