safer power for sensitive electronics
Unlike competitive products that can damage and degrade sensitive home
electronics with unstable power quality or high levels of total harmonic
distortion (THD), Lennox™ generators deliver cleaner, more stable power
that meets strict utility requirements and electrical standards for THD.
reliable performance
Lennox’ commercial-grade digital controller provides increased peak motor-
starting capability and the highest-tested surge capacity for large start-up
loads such as air conditioning. Voltage regulation varies only +/- 1.5%, even
under a full-house load. Quality extends to the outside, too, where the salt-
spray-tested paint used on exterior surfaces provides lasting durability and
rust prevention.
Quieter operation
Sleek, weather-resistant sound enclosures keep operating noise levels the
lowest among all competitive units tested—10 times quieter than the leading
competitor.* You and your neighbors won’t be bothered when the unit
performs self-diagnostic test runs, or when it’s running at full operation speed.
Quicker response time
When an outage occurs, Lennox generators restore power in as little as
10 seconds—three times faster than competitive models.
automatic diagnostic testing
Lennox generators perform a ꢀ0-minute, full-speed, self-diagnostic test each
week to ensure peak running condition.
simple installation and maintenance
Fast, flexible installation is accomplished through a simple wiring connection
with the automatic transfer switch and an integrated polymer pad on the
air-cooled RGEN1ꢀ and RGEN17. No break-in time is needed once the unit is
installed—all Lennox generators are tested and ready to use prior to shipping.

sound facility qualified in accordance with ANSI standard S1ꢀ.3ꢀ-1990.

The automatic transfer switch is the key component of your backup power system. When
an outage occurs, it automatically transfers power from the utility to your generator.
When utility power is restored, the transfer switch signals the generator to shut down,
and puts your home back on the utility power.
