GENERAC GUARDIAN SERIES 20KW GENERATOR FEATURES AND BENEFITS
This generator provides essential circuit power protection for your home during a power outage, ensuring that essential appliances maintain power. This standby generator is automatic and offers protection year-round, for less than the cost of central air conditioning.
Every Guardian Series home standby generator comes with Mobile Link™ Remote Monitoring. Remote Monitoring is FREE, and allows you to monitor the status of your generator from anywhere in the world. Use a smartphone, PC, or tablet to access generator information, such as the current operating status and maintenance alerts. By connecting your account you have access to authorized service dealers for fast, friendly, and proactive service.
Generac generators are ideal for weathering storms and power outages. Their automatic backup power gives you piece of mind that your home and appliances are protected.
Generac generators and engines are designed, engineered and assembled in the USA using domestic and foreign parts.
The Generac G-Force Engine is built to handle the stressors of generator use. This results in power that’s more reliable and requires less routine maintenance than competitor engines. Generac’s new G-Force engine is purpose built and pressure-lubricated. It features hydraulic lifters, which improve engine performance and extending the life of the product. (Hydraulic lifters only available on the 13 & 16 kW.)
