16 kW Air-Cooled Generator     

16 kW Air-Cooled Standby Generators

Big Generator Protection… Half the Price
More power, more features and an exceptional price make the GUARDIAN QuietSource™ 16 kW the best value in automatic standby generators.  With GUARDIAN’s new breakthrough technology, the 16 kW provides the circuit protection of a much larger generator at a truly remarkable price. If you need to run more than one air conditioner, the GUARDIAN QuietSource 16 kW is the affordable solution. With 33% more circuit coverage than our 13 kW, this powerhouse can start a 5-ton AND a 3-ton, or two 4-ton air conditioners with plenty of power to spare.

Whisper Quiet Operation GUARDIAN’s exclusive patent-pending Whisper-Test™ low speed exercise feature makes the GUARDIAN QuietSource 16 kW the quietest air-cooled generator on the market. Whisper-Test reduces noise to less than 59 dBA during the weekly automatic self-test. That’s quieter than your central air conditioner.

With our pre-packaged, 16-circuit pre-wired system, installation is fast, easy and inexpensive, making the 16 kW an even better value.
