Features and benefits
Robust Design – The generator is designed
to operate in cold weather with performance
down to 0 °F (-18 °C) out of the box. Cold
Weather accessories allow for even colder. It
is tested and certified per the latest EPA, UL,
and CSA standards. The generator meets
NFPA 37 which allows it to be installed 18
inches from a building. It has powerful motor
starting ability and can easily start and run a 5
ton A/C¹ under full pre-load.
Flexible Exercise Modes - Exercise modes
can be set for time, date, and frequency that
suits the owner. Our patented ‘Crank only’
exercise mode allows the generator to crank
the engine and run diagnostics without
starting the engine. This reduces wear and
tear on the engine, fuel costs, and further
reduces the sound of an already quiet
generator.
Intelligent Load Management - The
generator can control up to 4 loads and
continuously monitors how much power is
required independently for each load. It then
controls each load for maximum utilization of
generator power by only restoring loads the
generator has capacity to run.
Remote Monitoring - Remote monitoring is
built into every generator. Using a computer,
tablet, or smart phone, an operator can
monitor, change exercise modes, and
manually run the generator remotely.
Generator and ATS packaged sets
– The
RS20AC comes with a 20 kW generator and
200A service entrance rated ATS in one box
to make ordering more convenient.
