Guardian Elite models 16kW and 18kW are the quietest and most powerful air-cooled models of their size on the market today. You can protect selected circuits or all circuits, depending on your requirements. With OHVI® industrial engines these Elites are quiet, long lasting and maintain themselves with up to 2 years between oil changes.

BREAKTHROUGH DESIGN... GUARDIAN QuietSource™ generators are the most powerful, yet most economical air-cooled generators available today! Now with GUARDIAN's exclusive Whisper-Test™ feature, these 16 kW powerhouses run 50% quieter than central air during their weekly self-test. Available in either steel or our corrosion resistant aluminum enclosures, the GUARDIAN QuietSource™ 16 kW is just one more reason why...

America prefers GUARDIAN 5 to 1.

Whisper-Test™
Reduces noise to a whisper by lowering engine speed during the generator's weekly self-test. Models with Whisper-Test are as quiet as a car idling in the driveway during exercise, making them the quietest standby generators on the market.

OHVI® Industrial Engine
Generac's OHVI® (Overhead Valve Industrial) engines have been specifically designed for generator demands. The use of advanced technologies results in engines that are broken in right out of the box, feature service intervals of 2 years or 200 hours and have the longest life in the industry.

Superior Electrical Protection
The 10, 13, 16 and 18 kW air-cooled models feature an electronic governor, which maintains steady speed and eliminates voltage drop when loads are applied. This, as well as the automatic voltage regulator, provides a smooth rate of electricity, which is especially important for sensitive electronic devices such as computers.

Automatic Exerciser
An automatic seven (7) day test of your system allows you to verify that your generator is in peak operating condition at all times.

Automatic Transfer Switch
The automatic transfer switch automatically switches the source of power from the utility to the generator within seconds of a power outage. Because it’s automatic, you never have to flip a switch.

Convenient Fuel Supply
GUARDIAN and GUARDIAN QuietSource™ generators operate on natural gas or LP gas service. This provides you with unlimited run time during extended utility power failures.

Maintenance Friendly
Air-cooled models feature a hinged top and removable front panel. Liquid-cooled models feature large, removable doors. This provides easy and quick access for maintenance and servicing.
